A building facade is constantly exposed to the weather, so it's no surprise that defects can develop over time. Small issues like cracked brickwork, damaged sealants or blocked gutters are easy to miss, but they can quickly lead to more costly repairs if they're left unchecked.

That's why regular facade inspections are so important. By spotting problems early, you can plan maintenance before defects become safety risks or cause significant damage to the building.

This facade inspection checklist is designed to help property managers, facilities managers and building owners carry out a simple visual inspection of their building's exterior. Follow it as part of your planned maintenance programme to identify common issues, keep accurate records and decide when professional repairs or a more detailed survey may be needed.

How to Use This Facade Inspection Checklist

Use this checklist to support routine visual inspections as part of your planned maintenance programme. It's intended to help you identify common signs of deterioration and keep a clear record of any issues you find.

Before you begin, review any previous inspection reports or known defects, then use the checklist to guide your inspection as you move around the building. Take photographs as you go and note the location of any cracks, damage or areas that need further attention.

Not every section will apply to every building. For example, some properties won't have cladding or balconies, while others may include several different facade materials. Simply complete the sections that are relevant to your building.

If you identify significant damage, loose materials or areas that can't be safely inspected from the ground, arrange a more detailed inspection using the appropriate access method. Specialist surveys, including rope access inspections, can investigate high-level or concealed defects that aren't visible during a routine visual check.

Building Facade Inspection Checklist

The checklist below covers the key areas to consider during a routine facade inspection. Use it as a guide to help you carry out a thorough visual assessment, recording any defects or maintenance issues you identify along the way.

Set Up Your Inspection Record

A little preparation before you start will make your inspection much more organised and easier to repeat in future. The aim is to create a consistent record that helps you monitor changes over time, communicate defects clearly and plan any maintenance that may be needed.

Before heading outside, take a few minutes to:

• Review any previous inspection reports, repair records or known defects so you know which areas may need closer attention.

• Identify the main facade materials used on the building, such as brick, render, cladding or concrete. Different materials can develop different types of defects.

• Decide how you'll identify each part of the building. For example, use the front, rear, left and right elevations, or north, south, east and west. For larger buildings, it can also help to split each elevation into floors or sections.

• Prepare a simple inspection record. Include the building name, inspection date, weather conditions, the location of each defect, photographs, recommended actions and a priority level for any repairs.

• Make sure you have a camera or mobile phone for photographs, along with a way to record your findings as you move around the building.

Your inspection record doesn’t need to be complicated. What matters is that each issue is recorded clearly enough for someone to understand where it is, what was found and what needs to happen next.

A simple record could look like:

Priority categories can be flexible, but their purpose is simple: they help you decide how quickly each issue needs attention, for example:

• Immediate: Make safe or arrange urgent professional advice now.

• Urgent: Arrange repair or investigation as soon as practical.

• Planned: Add to your upcoming maintenance programme.

• Monitor: Photograph, record and review at the next inspection.

Once you're ready, begin your inspection from ground level and work systematically around the building, updating your inspection record as you go.

Complete a Ground-Level Visual Inspection

For most routine facade checks, the main inspection will be a visual assessment from ground level. This allows you to review the overall condition of the building, identify visible defects and decide whether any areas need closer inspection.

Choose a logical route around the building and inspect one elevation at a time. The exact order matters less than using a consistent approach that makes your notes easy to follow and your findings easy to compare at future inspections.

For each elevation:

• Stand far enough back to view as much of the facade as possible, where it is safe and practical to do so.

• Take an overview photograph before recording individual defects.

• Scan from high level to low level, checking the roofline, upper facade, windows, main wall areas and ground-level details.

• Pay close attention to areas where defects commonly develop, such as entrances, exposed corners, areas below gutters, window openings, parapets, balconies and projecting features.

• Look for patterns, not just isolated defects. Repeated staining below windows, cracking around several openings or algae growth across one elevation may point to a wider issue.

• Check lower-level areas for impact damage, damp staining, vegetation growth or signs of poor drainage.

• Use binoculars, a zoom lens, your phone’s zoom or even drone photography (where available with the correct permissions) to help review high-level areas from the ground.

• Record any areas that are hidden, too high or not safe to inspect properly.

Where something is unclear, record what you can see and note whether closer inspection is needed. High-level staining, repeated cracking or loose materials may all point to wider issues, even if the exact cause cannot be confirmed from the ground. The important thing is to flag these issues early so they can be reviewed properly, whether using roof access, rope access, a MEWP or another suitable access method.

The aim is to build a clear overview of the facade while identifying the areas that need closer attention. By inspecting each elevation in a consistent way, you’ll be less likely to miss important defects and more likely to create a record that can be reviewed, repeated and acted on.

The following sections will help you focus on the main features and materials to check as you carry out this visual inspection.

Check Rooflines and Water Management

The roofline may not be the first thing you think of during a facade inspection, but it has a major impact on the condition of the walls below. Blocked gutters, leaking downpipes, failed flashings or displaced copings can all direct water onto the facade, leading to staining, damp, biological growth and gradual deterioration.

As part of your ground-level visual inspection, check:

• Gutters for visible blockages, plant growth, sagging or overflow staining.

• Downpipes for leaks, damaged joints, missing sections or water discharging onto the wall.

• Hoppers and outlets for signs of blockage or overflow.

• Flashings around roof edges, upstands and wall junctions for visible gaps or deterioration.

• Copings, cappings and parapet edges for cracking, displacement or open joints.

• Staining below gutters, parapets, balconies or roof edges.

• Areas where water appears to run down the facade rather than being directed away from it.

• Ground-level drainage where water collects near the base of the wall.

You may not be able to confirm the condition of roofline details from ground level, especially on taller buildings. However, visible staining, repeated overflow marks or vegetation in gutters are all useful warning signs. Record these areas clearly and arrange closer inspection or maintenance where needed.

Inspect Windows, Doors, Joints and Common Failure Points

Many facade problems begin at junctions rather than across the main wall surface. Windows, doors, joints, vents and other openings all interrupt the facade, creating places where water can get in or materials can start to fail.

As you inspect each elevation, pay close attention to:

• Window and door surrounds: Look for cracked sealant, open gaps, staining below frames, damaged sills or signs that water is tracking around the opening.

• Sills, heads and lintels: Check for cracking, movement, staining or damaged masonry around the top and bottom of openings.

• Movement and expansion joints: Look for split, missing or hardened sealant, widened gaps, staining or signs that the joint is no longer allowing movement properly.

• Vents, pipes and service penetrations: Check that any penetrations through the facade are sealed neatly and have not left gaps where water can enter.

• Lights, signs, brackets and fixings: Look for loose fixings, rust staining, redundant holes or damage around attachment points.

• Changes in material: Pay close attention where brick meets render, cladding meets masonry, or glazing meets the main wall. These transitions often rely on sealants, flashings or trims to keep water out.

• Shopfronts, shutters and access doors: On commercial buildings, check for damaged frames, corroded shutters, loose trims and gaps around thresholds or side channels.

These areas are easy to overlook because they often appear small compared with the rest of the facade. However, a failed sealant joint or poorly sealed fixing can allow water to enter long before there is any obvious damage to the main wall surface.

If you notice staining, repeated sealant failure or damage around several openings, treat this as a pattern rather than a one-off defect. Record the affected areas clearly and consider whether a wider repair programme may be needed instead of isolated patch repairs.

Check the Main Facade Materials

As you inspect each elevation, pay attention to the specific materials used on that part of the building. Brickwork, render, cladding, concrete and metal elements all have different maintenance needs, so the warning signs will vary depending on the material and facade construction.

The sections below highlight common defects to look for across typical facade materials. Pay particular attention to junctions between materials, as these areas are often more vulnerable to movement, staining and water entry.

Brick, Stone and Masonry

Brick, stone and masonry facades are durable, but they still need regular checks. Pay close attention to the condition of the masonry units themselves, the mortar joints between them and any signs that water is being trapped or drawn into the wall.

Look for:

• Cracked bricks, stone or blockwork: Note whether cracks are isolated or repeated across the elevation, especially around windows, corners and changes in level.

• Spalling or flaking surfaces: This can appear as brick faces breaking away, stone surfaces scaling, or masonry becoming soft and crumbly.

• Open or deteriorating mortar joints: Look for missing, loose, deeply recessed or crumbling mortar, particularly in exposed areas and below gutters or downpipes.

• Bulging or uneven sections: Any visible bowing, displacement or movement in the wall should be recorded and reviewed by a suitable professional.

• Efflorescence or white staining: White salt deposits can indicate moisture moving through the masonry. Record where it appears and whether it is recurring.

• Vegetation growth: Plants, moss or weeds growing from joints can hold moisture and may indicate open joints or poor maintenance.

• Staining below rainwater goods: Dark staining, algae or repeated damp marks below gutters, hoppers and downpipes may point to leaks or overflow.

• Failed previous repairs: Watch for patch repairs, hard cement pointing, mismatched mortar or repairs that are cracking away from the surrounding masonry.

On older or historic buildings, be particularly careful when assessing mortar. Lime mortar can look softer than modern cement-based mortar while still performing well. The concern is usually mortar that is open, loose, deeply eroded or trapping moisture, rather than mortar that simply looks aged.

If you suspect widespread movement, recurring water damage or inappropriate previous repairs, record the affected areas and arrange further assessment before carrying out remedial work.

Render

Rendered facades can include traditional lime render, cement render, silicone render, acrylic render, polymer render or monocouche systems. Each type performs slightly differently, so it is useful to know what kind of render you are inspecting before deciding on the right repair or cleaning method.

Look for:

• Cracking: Record fine crazing, wider cracks, diagonal cracks from openings or repeated cracking across the same elevation. Cracks can allow water behind the render and may also point to movement, poor detailing or an unsuitable previous repair.

• Bulging or hollow areas: Render that appears swollen, bowed or detached may have lost its bond with the substrate. Where safe and accessible, hollow-sounding areas can also indicate detachment.

• Delamination or flaking: Look for areas where the render surface is peeling, breaking away or separating in layers.

• Crumbling or powdering: Friable, soft or powdery render may be deteriorating due to age, moisture, salts or incompatible materials.

• Staining and streaking: Dark streaks, water marks or discolouration below gutters, copings, windows or parapets may suggest water is running across the facade.

• Algae, moss and organic growth: Green, black or red staining can build up on shaded or damp elevations, particularly where the surface stays wet for long periods.

• Impact damage: Check lower-level areas, corners, entrances and service areas for chips, dents or broken sections.

• Failed previous repairs: Watch for patch repairs that are cracking, visibly mismatched, holding moisture or pulling away from the surrounding render.

Older lime renders need particular care. They are usually more breathable and flexible than many modern cement-based systems, so unsuitable repairs or impermeable coatings can trap moisture and accelerate deterioration. If you are unsure what type of render is present, record the issue and seek specialist advice before arranging cleaning or repair.

Render cleaning should also be approached carefully. High-pressure washing or the wrong chemical treatment can damage the surface, especially on softer or older renders. If staining or biological growth is widespread, note the affected areas and arrange professional cleaning using a method suited to the render type.

Cladding and Panel Systems

Cladding systems should be checked for both appearance and performance. The aim is to spot visible signs that panels, joints, fixings, flashings or finishes are starting to fail, as these details often determine how well the system sheds water and resists weathering.

Look for:

• Loose, displaced or damaged panels: Record any panels or boards that appear out of line, bowed, cracked, dented, warped or insecure.

• Open joints or gaps: Check for widened joints, missing trims, open board gaps or areas where water could enter or collect rather than drain as intended.

• Damaged fixings: Look for loose screws, missing caps, staining around fixings or signs that panels or boards have moved.

• Failed sealants, gaskets or trims: Check around panel joints, windows, doors and service penetrations for cracked sealant, loose gaskets or missing trims.

• Flashings and water run-off: Look for corroded, displaced or poorly draining flashings, as well as staining that suggests water is being directed across or behind the cladding.

• Coating or finish failure: Record peeling, chalking, blistering, fading, flaking or areas where protective coatings appear to be breaking down.

• Timber-specific issues: If timber cladding is present, look for warping, splitting, cupping, loose boards, coating failure or areas where moisture appears to be trapped. Some greying and colour variation may be normal on uncoated timber, but uneven staining, decay or movement should still be recorded.

• Biological growth or staining: Algae, moss, dark streaks or repeated staining may indicate that the surface is staying wet or that water is not draining as intended.

• Previous patch repairs: Note any mismatched panels, temporary repairs or areas where earlier repairs appear to be failing.

If you manage a building with cladding, it’s important not to assume that a ground-level inspection can confirm the full condition of the system. Some defects may sit behind the panels or at high-level junctions. Also, keep in mind that for certain higher-risk buildings, routine visual checks must sit alongside formal statutory external wall fire risk assessments (such as FRAEWs).

If you notice movement, repeated staining, loose panels or concerns about the type of cladding installed, arrange a specialist inspection using an appropriate access method.

Concrete

Concrete facades may include exposed concrete panels, precast units, columns, balcony edges, soffits or decorative architectural features. During a routine inspection, focus on signs that water is affecting the concrete or that reinforcement may be starting to corrode.

Look for:

• Cracking: Record the location, direction and extent of any cracks. Cracks around openings, balcony edges, joints or repeated across one elevation may need closer review.

• Spalling: Look for areas where concrete has broken away, flaked off or left rough patches on the surface.

• Rust staining: Brown or orange staining can indicate corrosion of embedded steel reinforcement, especially where it appears alongside cracking or spalling.

• Exposed reinforcement: Any visible steel should be recorded and treated as a priority for professional assessment.

• Delamination or hollow areas: Concrete that sounds hollow when safely tapped, or appears to be separating from the surface, may be losing its bond.

• Surface erosion or powdering: Record areas where the surface is becoming soft, dusty, pitted or uneven.

• Water staining and efflorescence: White deposits, dark streaks or damp patches may suggest water is moving through or across the concrete.

• Defects around joints and edges: Pay close attention to panel joints, movement joints, balcony edges, soffits, parapets and corners, where water can collect or detailing can fail.

• Failed coatings or previous repairs: Look for peeling coatings, patch repairs that are cracking, mismatched repair areas or signs that earlier works are deteriorating.

Concrete defects should not be ignored, particularly where cracking, spalling or rust staining is present. These issues can be linked to reinforcement corrosion, water penetration, carbonation or salt exposure, especially on exposed, coastal or high-traffic sites.

If you identify recurring cracking, loose concrete, exposed reinforcement or widespread staining, arrange a closer inspection by a suitable professional before planning repairs.

External Timber Elements

External timber elements can include window frames, doors, sills, fascias, soffits, shopfronts, cladding, canopies, decorative features and other exposed joinery.

In our experience across hundreds of facade maintenance projects, this is one of the most common areas where support is needed, as timber can deteriorate quickly once coatings fail or water is allowed to sit in joints, end grain or lower sections.

Look for:

• Peeling, flaking or cracked paint: Some coatings protect external timber from moisture and UV exposure. Once they break down, the timber beneath can start to absorb water.

• Soft, decayed or crumbly timber: Pay particular attention to window sills, bottom rails, thresholds, lower door sections and areas close to standing water or poor drainage.

• Open joints or gaps: Check mitred corners, panel joints, glazing beads, frame joints and junctions between timber and surrounding materials.

• Splitting, checking or cracking: Some surface movement is normal, but wider cracks can allow water into the timber and accelerate decay.

• Warping or distortion: Look for bowed doors, twisted frames, sticking windows or timber elements that no longer sit squarely.

• Failed putty, sealant or glazing beads: Gaps around glass, beads and frame edges can allow water into vulnerable areas of the joinery.

• Staining, mould or algae growth: Dark staining, green growth or persistent damp marks may indicate that the timber is staying wet for too long.

• Exposed end grain: Cut ends, lower edges and projecting details are especially vulnerable if they are not properly sealed or coated.

• Loose ironmongery or fixings: Check hinges, handles, locks, brackets and screws for corrosion, looseness or damage to the surrounding timber.

• Previous patch repairs: Note filler repairs, poorly matched timber inserts, repeated painting over decay or areas where earlier repairs are opening up again.

Not every change in timber is a defect. Some uncoated timber will naturally weather to a grey or silver tone, and small seasonal movement is expected. The main concern is timber that is staying damp, losing its protective coating, becoming soft or allowing water into the building fabric.

Older timber windows, doors and decorative joinery can often be repaired rather than replaced, especially where decay is localised. Historic England and SPAB both emphasise that repair is often preferable for traditional timber windows, provided the work is carried out by a skilled joiner using suitable materials.

External Metal Elements

Metal elements on a facade can include railings, balconies, canopies, grilles, louvres, shutters, doors, window frames, brackets, fixings, trims and decorative features. These areas are often exposed to rain, pollution and repeated use, so small defects can develop into corrosion, staining or loose components if they are not maintained.

Focus especially on places where water can sit, coatings can fail or metalwork is fixed back into the building.

Look for:

• Rust, corrosion or staining: Record rust patches, orange staining, bubbling paint or corrosion marks running onto nearby render, stone, brick or cladding.

• Failed protective coatings: Look for peeling, flaking, blistering, chalking or worn paint, especially on exposed edges, corners, railings, gates and window frames.

• Water traps and crevices: Check bases, footings, fixings, joints, overlaps and areas behind or below metalwork where water, dirt or debris can collect.

• Loose or missing fixings: Record loose bolts, missing screws, failed brackets, damaged caps or fixings that appear to be pulling away from the facade.

• Movement or distortion: Look for bowed railings, bent panels, misaligned gates, distorted frames or metal elements that no longer sit correctly.

• Damage around penetrations: Check where signs, lights, brackets, vents, pipes or handrails are fixed through the facade. Poor sealing around these points can allow water into the surrounding material.

• Contact between different metals: Note any areas where different metals meet, or where staining suggests a reaction between fixings, panels, flashings or rainwater goods.

• Moving parts: Check doors, shutters, gates, louvres and opening windows for seized hinges, corroded tracks, stiff operation or damage caused by repeated use.

• Debris and dirt build-up: Look for leaves, bird droppings, pollution deposits or trapped dirt on ledges, horizontal surfaces and sheltered areas that are not naturally washed by rain.

• Failed previous repairs: Record patch painting, temporary fixings, mismatched metalwork or areas where earlier repairs are already rusting or pulling away.

Not every change in metal appearance is a defect. Some metals naturally weather or develop a patina. However, active corrosion, flaking coatings, loose fixings, trapped moisture and staining onto adjacent surfaces should be recorded and reviewed.

Where corrosion is widespread, metalwork is loose, or fixings appear to be failing, arrange a closer inspection before cleaning, repainting or carrying out repairs. The right treatment will depend on the metal type, coating system, exposure level and condition of the surrounding facade.

Plan and Prioritise Repairs

Once you've completed your inspection, take a step back and review your findings as a whole. Rather than looking at each defect in isolation, consider whether there are any patterns that point to a wider maintenance issue. For example, repeated staining below rainwater goods may indicate ongoing water management issues, while recurring cracks around several openings could point to movement or deterioration that is affecting a wider area of the facade.

Next, prioritise any repairs based on the likelihood of the defect becoming worse if left unattended. The priority categories in your inspection record provide a simple way to organise your findings:

• Immediate: Make safe or arrange urgent professional advice where there is a significant risk of further damage or a potential safety concern.

• Urgent: Arrange repair or further investigation as soon as practical to prevent the defect from deteriorating.

• Planned: Include the work within your next planned maintenance programme where the issue is stable but should not be left indefinitely.

• Monitor: Continue to photograph and record the defect, reviewing it during future inspections to check whether it is changing over time.

Not every issue can be confirmed during a routine visual inspection. Where defects appear widespread, affect high-level areas or suggest concealed damage, arrange a more detailed inspection using the appropriate access method. This may include roof access, a MEWP or a rope access survey, depending on the building and the location of the defect.

Finally, update your maintenance plan to reflect the work required. By comparing each inspection against previous records, you'll be able to identify recurring problems, monitor whether defects are changing and demonstrate that the building is being managed proactively over time.

How Often Should You Inspect a Building Facade?

There is no single inspection frequency that suits every building. The right schedule will depend on factors such as the building's age, height, construction, exposure to the weather, previous defects and the level of risk associated with the facade.

As a guide, most buildings should have a routine visual facade inspection at least once a year as part of a planned preventative maintenance (PPM) programme. Additional inspections should also be carried out after severe weather, impact damage, major building works or whenever new defects are reported.

For higher-risk buildings, or where previous inspections have identified recurring issues, more frequent inspections or periodic specialist surveys may be appropriate. This is particularly important for buildings with complex facades, extensive cladding systems or areas that cannot be adequately assessed from ground level.

Industry guidance, including BS 8210 and SFG20 maintenance schedules, promotes a planned, risk-based approach to building fabric inspections rather than waiting for defects to become obvious. Keeping accurate inspection records and comparing findings over time makes it much easier to identify deterioration early and plan repairs before they become more disruptive or expensive.

If you're developing a wider maintenance strategy, our guide to creating an exterior PPM schedule explains how facade inspections fit alongside routine maintenance of roofs, rainwater goods, windows and other external building elements.
