Case Study:Protecting a Riverside Residential Property with Careful Metalwork Repairs

Spectrum Specialist Support has been carrying out a programme of external restoration works to protect this property, improve its appearance and extend the life of its balconies. Over the course of several months we will be carrying out a range of repair and redecoration works.

This first case study focuses on the balcony restoration phase of the project. Across the property, many balconies were showing the natural signs of age and exposure, including peeling paint, tired timber handrails and rusted metalwork. In some areas, the corrosion had moved beyond surface-level staining and into the metal durbar sheets themselves, meaning redecoration alone would not have provided a responsible long-term repair.

Working for FirstPort, a long-term property management client of ours, we developed a careful programme of metalwork restoration, sheet replacement, timber repairs and surrounding stone cleaning, all while the building remained fully occupied.

The Project

The works were originally prompted by a planned condition survey. The property is expected to undergo periodic redecoration every 8-10 years, and FirstPort appointed a surveyor to review the condition of the building.

During this inspection, it became clear that a number of balcony metal sheets were too badly corroded to be redecorated. On the original schedule, 40 balconies were listed, made up of 223 metal sheets. As the project progressed and the balconies were opened up for closer inspection, further deterioration was discovered, adding approximately eight more balconies to the replacement scope, with the possibility of further additions as the project continues.

For us, the task was not simply to repaint the balconies. The priority was to distinguish between surfaces that could be restored and protected, and those that needed replacement to preserve the long-term integrity of the structure.

The Challenge

Although the blocks looked similar, we found several differences from what had initially been expected once works began.

The site comprises several separate blocks, and appears to have been constructed by multiple building companies, each using slightly different methods. As we moved from block to block, we found changes in fixings, welding, support beams, edge details and balcony lips. These differences affected how each metal sheet could be removed, replaced and protected.

This meant the project had to remain flexible. We worked closely with the surveyor throughout, assessing each block on its own merits and agreeing the most suitable solution for each balcony.

There were also the usual challenges of working across an occupied residential property. Some balcony works required access through residents’ homes, particularly where metal sheets had to be replaced. Clear communication became an important part of the project, with residents receiving direct notices, emails and phone calls. The concierge was also given weekly progress updates, helping residents understand where the team would be working and when balconies needed to be cleared.

The Access

Rope access was used as the main access method, helping our team reach high-level balcony areas without surrounding the property with scaffolding.

The existing safety system was tested and used for the works, with deadweight trolleys available on site as a backup. This gave us the flexibility to move efficiently across the elevations while keeping disruption to the wider site low.

The project also required careful public and resident protection. We used barriers and signage to cordon off working areas, while operatives used appropriate PPE and tool lanyards when working overhead.

For a busy residential site, this access strategy made a meaningful difference. Scaffolding around the blocks would have created significant disruption for residents, restricted light and made the site more difficult to manage. By using rope access predominantly, we were able to keep the works moving while maintaining day-to-day access around the property.

Our Solution

We delivered a condition-led balcony restoration programme, combining repair, replacement and redecoration.

Where the metalwork was stable, we prepared and redecorated it. Where rust had penetrated too deeply into the metal plates, the affected durbar sheets were replaced.

For the metalwork redecoration, the process included protecting walls, glass and handrails with tape, removing flaking paint and rust by sanding, applying Hammerite Rust Remover Gel, and making sure painted surfaces were stable and properly keyed.

Any areas affected by rust were primed with Hammerite Red Oxide Primer before all metalwork was finished with two coats of Hammerite Direct to Rust Smooth metal paint. This system gave the restored metalwork a clean finish while adding a protective barrier against future corrosion.

The timber handrails were also restored as part of the balcony works. Any sections beyond repair were replaced. The remaining timber was sanded back to bare wood, filled where required using Ronseal Dark Wood Filler, and coated with at least two coats of Sadolin Wood Stain.

This combination of metal and timber care helped restore the balconies as complete features, rather than treating each material in isolation.

Wider Building Care

Although this first case study focuses on balcony restoration, the project also included surrounding stone and brickwork repairs.

Window sills, decorative stone banding and coping stones were cleaned using the DOFF system, which uses superheated steam at low pressure to remove staining and biological growth without damaging the surface beneath.

Some brickwork areas were also cleaned where specified by the surveyor, particularly where staining or moss growth had developed.

As the team progressed, coping stones were found to need more attention than first expected, particularly at Falcon House and Consort House. Some copings required re-bedding, while many needed repointing. At Consort House, we re-pointed  most of the copings because the loose joints had been allowing water into the building.

This wider package of works reflected our approach to building care. A balcony may be the visible issue, but the surrounding details often reveal where longer-term deterioration has started to develop.

Working With the Weather

We planned the programme carefully around the drying times of paints and wood fillers.

The balcony redecoration works were prioritised during the spring ad summer months, when temperatures were suitable for the specified coatings. Once winter arrived and temperatures consistently dropped below 8°C, the team shifted focus towards sheet replacement works, where the colder conditions would not affect the finish of the paint system.

This flexible plan helped maintain quality while keeping the project moving.

The Result So Far

The balcony restoration works at St David’s are ongoing, but the redecorations already completed have been well received by both residents and FirstPort.

The restored balconies now look cleaner, brighter and better protected. Rusted areas have been treated or replaced, tired timber has been repaired, and surrounding stone and brickwork has been cleaned and improved where required.

Just as importantly, the project has been delivered with careful communication. On a residential site, successful restoration is not just measured by the final finish. It is also measured by how well residents are informed, how disruption is managed, and how quickly the team can respond when new issues are uncovered.

At St David’s, we have continued to adapt as the building has revealed more about its condition. Each balcony, fixing and sheet replacement has required attention to detail, careful planning and close collaboration with the surveyor, FirstPort and the residents.

This is ongoing building care in practice: listening to the condition of the property, responding with the right repair, and protecting the building for the years ahead.

For property managers and surveyors planning balcony restoration works, this project shows the value of a flexible access strategy, clear resident communication and a repair-first approach to building maintenance.

When a building begins to show signs of age, the right response is not always a single service. Sometimes, it takes a full Spectrum of repairs.
