- Dust and loose debris are cleaned from each gap.

Fire rated sealant in Sunninghill
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. We work on pipe & cable gaps, linear gaps and door frames, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and holes left by a change of layout.
Around a place like Sunninghill, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.
Every job is covered by our 12-month guarantee, wherever you are in Windsor and Maidenhead.

What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Around Sunninghill, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Anti-fungal sanitary silicone in wet areas
- We never seal over old sealant

Signs you need fire rated sealant in Sunninghill
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
These are the problems we are asked about most:
- Gaps where walls meet ceilings or slabs
- Open gaps behind door architraves
- Sealant items on a fire risk assessment action list
- Old fire sealant that has split or come away

Sunninghill: your questions answered
Do you cover smaller places like Sunninghill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Ascot station. Can you help?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you insured?
Yes. We’re fully insured.
How much does fire rated sealant cost in Sunninghill?
Size, access and the old material all affect the cost. Ask us for a quote.
Can you fill the gap behind a fire door frame?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
Commercial buildings in Sunninghill
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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Community buildings like Church of St Michael and All Angels are part of the picture too: gaps around pipes and cables are worth checking after any building work there. If you look after a building such as St Michael's CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
- Plan fire stopping into any work that goes through walls or floors
- Photograph sealed gaps before they’re covered up
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
