Our Commercial Drainage Services

Our expert team can diagnose and resolve a broad range of commercial drainage issues, including quick-response drain unblocking and cleaning. As we understand that blocked drains can cause severe damage and disruption, we offer a 24/7 emergency drain unblocking call-out service. Our team is equipped to tackle all of your drain blockage issues and will test the entire system before leaving.

In addition to drain unblocking, we can carry out regular commercial drain maintenance. With access to ground drainage, we will clean drain runs, sub runs and gully runs. We can also tackle the base of stacks and downpipes. For a comprehensive clean, all surface drains will be cleaned, along with any gullies running through to walkways and common areas. Rainwater drains are also cleaned using a plough jet to keep silt levels low. Any further defects will also be reported and any debris removed.

Extensive Gutter Maintenance and Repairs on Entire Housing Estate

A three-day project managed by Spectrum involved repairing and cleaning the gutter systems of six residential towers in Red Hill, using innovative scaffold-free methods. By employing a van-mounted cherry picker and modular pole systems, Spectrum accomplished comprehensive gutter cleaning, leakage repairs, and roof tile replacements efficiently and without the need for expensive scaffolding. The process included pre-site assessments, efficient debris removal, and detailed camera inspections, culminating in a fully operational, tested roofing and drainage system across the estate.

Frequently asked questions

What are our core commercial drainage services?

When it comes to drains, we operate a number of core services, including:

Drain unblocking

We offer a fast response to blocked drains for both commercial and domestic clients, 24 hours a day, 365 days a year.

Drain jetting

Drain jetting is a high-pressure cleaning method for blocked drains and sewer pipes. It works by pumping water from stored tanks through a high-pressure hose fitted with a jetting nozzle.

Drain runs, sub runs and gully run cleaning

Surface drains can be cleaned, along with any gullies running through to walkways and common areas, all we need is access to the inspection chamber.

Drain repairs

If your drains show signs of being cracked or broken, we can offer no-dig drain repairs such as patches and lining, or if it is needed, full drain excavation.

Drain surveys

If you suspect an issue with your drainage system, it is better to investigate now rather than waiting for the issue to get worse. We carry out extensive drain surveys and also provide you with a full report on our findings – giving you the peace of mind you deserve.


In short, if it’s to do with drains, then we can deal with it – from cleaning to maintenance to repairs. If you would like to know more about our drain services, or to speak to one of our operatives about your drain concerns, get in touch with a member of our team.

Alternatively, if it’s an emergency, call us up and we will be with you as soon as possible to resolve your issue. We won’t let a drain blockage cause you too much trouble, and our services aim to have the least possible impact or disruption on your life.

Do you offer emergency drain unblocking?

We know that sometimes life gets in the way and you just don’t have the time to get around to drain maintenance. We also know that drainage issues can occur out of sight or underground. That’s when problems can arise quickly and you need help in a hurry.

Whether you need routine maintenance, or an emergency call-out, we can help you with your drainage issues. Here at Spectrum, we offer a 24/7 emergency call out and commercial drainage service, so no matter when your drain emergency happens, we can be there to help.

We know that drains matter, and when you have a problem with your drains it can be a real worry. That is why we are on hand to clean drains when you need us most. As always, we ensure our drain cleaning service minimises any disturbance or mess. This is why we are trusted by some of London’s biggest residential blocks to maintain and repair their drains when issues arise.

What is a CCTV drain survey?

It can often be difficult to gain access to a drain blockage. However, at Spectrum, we specialise in projects with access challenges and will be able to help, even if you can’t see, reach or find the problem’s source.

Our drainage technicians use state-of-the-art CCTV drain inspection cameras to survey the internal workings of your property's drainage system. We can locate blockages, investigate cracks and root ingress, and create diagrams for clients who need accurate documentation of their drainage system.

With an accurate understanding of your complete drainage system, we can unblock drains and make any required repairs with minimal possible disruption.

Do drains need to be cleaned?

Drains are an integral part of your property that can be easy to forget. They remove waste and water from your property, keeping it free from flooding, build-up and debris that can cause problems. However, if your drains are blocked or damaged, a build-up of matter or cracked pipes can cause serious issues – and when the worst happens, it can be very unpleasant.

That’s why scheduled drain maintenance and drain cleaning is so important. Not only will this help to keep your drains free from blockages, but it can also help professionals spot drainage issues before they become a major problem.

Giggs Demetriou

Great company, we had a leak on one facade a facade of an 18m + building in Hackney and from the point of contact with Spectrum it was a positive experience. The team came this week and couldn’t have been more helpful and did everything within their power to help identify and hopefully resolve the issue they had everything on the van to resolve the problem we identified. The cost savings were substantial and I would certainly use them again if I had a similar issue. Thanks to all involved. Steve (The Fisheries)

Steve Watkins

Spectrum recently undertook some roofing repairs to a block of flats, which included cleaning gutters, replacing slipped slates, masonry repairs and mending guttering. Although it was a small job focusing on a narrow range of skills, they were very professional and workmanlike, worked efficiently so complete the job in 3 days, had excellent communication and charged a competitive rate. Changes in scope, start date and costs were all negotiated sensibly, and after completion issued with a report showing detailed photos of the repairs, most of which were not visible from ground level. This is helpful to document the condition they left the site in, and is also helpful survey information for planning future phases. Would happily use Elijah and his team again.

M Loosley

I have been using spectrum at multiple properties we manage for a nearly 2 years now, the admin team are always quick to respond and answer all our questions efficiently. The works are carried out swiftly and to a very high standard. Will always recommend Spectrum to my clients and colleagues.

Grace Taylor

Brilliant service, we used the roof cleaning service and would highly recommend using these guys.
