About our fire rated sealant in Hounslow
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, one gap at a time. Common call-outs are for fire seals that have cracked with movement and door frames with gaps between frame and wall, across flats & HMOs, linear gaps and pipe & cable gaps.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Hounslow, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
You get a 12-month guarantee, the same in Hounslow as everywhere else we work.

Commercial buildings in Hounslow
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Rented homes near Sunbury station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. As a London address, Hounslow can be tricky for parking: let us know about parking bays, permits or a driveway.

What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In Hounslow, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Advice
Different surfaces, different methods
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before we start to keep disruption down.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.
FAQs for Hounslow
Is parking an issue for fire rated sealant in Hounslow?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Sunbury station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.
How do I get a quote for fire rated sealant in Hounslow?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.

What we can’t put right
It helps to know what we cannot do:
- Fire doors that need new seals, closers or hardware
- Sign-off of the building, which sits with building control or your assessor
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
- Linear gaps
- Door frames
- Pipe & cable gaps
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Flag any open gap you spot round a pipe or cable
- Ask every contractor to reseal any fire stopping they disturb
- Plan fire stopping into any work that goes through walls or floors
- File the fire-stopping record where your assessor can find it
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.
Work for landlords, hotels and businesses
Letting agents and landlords in Hounslow can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
If you manage several properties in or around Hounslow, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When to call us in Hounslow
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
- Open gaps behind door architraves
For buildings such as Church of St Dunstan, older buildings that have had new heating or wiring often have service gaps worth checking.
