Fire rated sealant in Three Bridges, done properly
We often work from an action list drawn up by a fire risk assessor on buildings across Three Bridges. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on door frames, pipe & cable gaps and plasterboard & masonry, and the jobs we see most are old fire sealant that has split or come away and gaps left after a refit or conversion.
Commercial work around a smaller place like Three Bridges generally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.

Fire rated sealant around Three Bridges
Three Bridges has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Three Bridges is part of Crawley, one of the post-war new towns. Crawley was planned with its own industrial and business areas, so workplaces sit close to the homes. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere.
Managing a site like Pound Hill Junior School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Three Bridges station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What we can’t put right

- Large holes that need a different fire-stopping system

Three Bridges questions
Will you come out to Three Bridges?
Yes. Three Bridges is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for hotels and guest houses in Three Bridges?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How much does fire rated sealant cost in Three Bridges?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email with a short description of the job.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, large or small.
Is intumescent sealant the same as 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.
Signs you need fire rated sealant in Three Bridges
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Signs it’s time to call us include:
- Sealant items on a fire risk assessment action list
- Ordinary sealant used where a fire-rated product was needed
- New service routes left unsealed after building work
- Fire seals that have cracked with movement
Community buildings like St Barnabas' are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Store the list of sealed gaps with your building paperwork
- Get damaged fire seals looked at promptly
- Photograph sealed gaps before they’re covered up
- Ask every contractor to reseal any fire stopping they disturb
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Why it’s worth doing now in Three Bridges
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. In a smaller place like Three Bridges, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- An ARBOMaster approved applicator
- Neat joints and a tidy finish
- We never seal over old sealant
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes from a few hours to a few days, depending on the number of gaps and the access. Parking around Three Bridges is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
