How we handle fire stopping in Coombe Hill
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. Site teams most often ask us about fire stopping installed outside its tested range and openings found when ceilings come down for a refit, on joints between fire-resisting walls and floors, linear gaps at wall heads and service gaps in risers. One point of contact handles commercial sealant work in Coombe Hill from the first photos to the final walk-round, for single jobs and planned programmes alike.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Joint width, depth and condition
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Access details, including height
- The postcode of the building
- When you need the work done
- The asbestos register, for older buildings
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Aftercare for building managers
For the best life from the joints:
- File the specified details where the next contractor can find them
- Flag new cables with no seal around them
- Brief every trade that openings they make must be sealed
- Foam or ordinary sealant is never a fire-seal repair
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Reviewing a building’s overall fire safety
- Large openings beyond what any sealant detail covers
- Approving the work on behalf of building control
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Cable penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints

What we’re called out for in Coombe Hill
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.
If one of these sounds familiar, it’s time for a closer look:
- Unsealed penetrations discovered above suspended ceilings
- Fire stopping installed outside its tested range
- Fire sealant pulled out of the opening
- Non-fire-rated filler around services
For an estates team at a campus like Kingston University (Kingston Hill Campus) (under half a mile south of Coombe Hill), summer M&E works are normally followed by a round of penetration sealing.
What your quote should include
- What site paperwork they can supply
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
Different surfaces, different methods
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail.
Fire-rated sealing for Coombe Hill buildings
Coombe Hill has three care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified. Plenty of hotels sit less than 2 miles from Coombe Hill. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Shop fits in centres such as Bentall Centre, 2.2 miles to the south-west of Coombe Hill, can bring new services through fire-resisting walls between units, which then need the specified seal. Industrial units on estates such as St. George's Industrial Estate (1.8 miles west of Coombe Hill) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Your questions answered
Can you work at a site such as St. George's Industrial Estate, by Coombe Hill?
Yes. Estates, retail parks and business parks around Coombe Hill, St. George's Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
What do BS EN 1366-3 and BS EN 13501-2 mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. That rating only holds when the product is installed to its tested detail.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
