Fire rated sealant for homes and businesses in Hampton Hill
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Common call-outs are for standard silicone or caulk in a fire-stopping gap and linear gaps at the head of walls, on plasterboard & masonry, door frames and pipe & cable gaps.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Hampton Hill, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
All of our work is guaranteed for twelve months.

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone isn’t the tested solution
- Fire doors that need new seals, closers or hardware

Questions from Hampton Hill
Is Hampton Hill in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Hampton Hill is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is parking a problem for a job in Hampton Hill?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Is standard sealant good enough for a fire gap?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
What fire rated sealant looks like in Hampton Hill
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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.
Letting a property close to Fulwell station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Hampton Hill United Reformed Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What else we do in Hampton Hill
Why act early in Hampton Hill
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Hampton Hill, the repair is bigger than the sealant job would have been.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How it works
At the end, we look at the finished work together. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. In a London area like Hampton Hill, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

Advice
Quotes for fire rated sealant in Hampton Hill
For a quick quote, just ask. The main things that affect it are:
- When we can work, for business premises
- The number of rooms or windows
- Any mould that needs treating
- The type of sealant required
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What we need to know
To help us quote quickly, please include:
- If someone has resealed it before
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- Whether it’s a home or a business
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Looking after it afterwards
Looking after new joints is easy:
- Make resealing part of every contractor’s brief
- Keep pictures of seals that will be hidden
- Get damaged fire seals looked at promptly
- Don’t paint over fire sealant until it has cured
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
Signs you need fire rated sealant in Hampton Hill
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
These are the problems we’re asked about most:
- Unsealed gaps around fire door frames
- Seals cut through by electricians, plumbers or data installers
- Holes left by a change of layout
- Ordinary sealant used where a fire-rated product was needed
Hampton Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
