About our fire rated sealant in Brompton
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on pipe & cable gaps, linear gaps and plasterboard & masonry, and the jobs we see most are sealant items on a fire risk assessment action list and unsealed gaps where pipes and cables go through a wall.
In a smaller place like Brompton, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
All of our work is guaranteed for twelve months, in Brompton and everywhere else we cover.

Commercial buildings in Brompton
If you run a hotel, guest house or holiday let in a coastal place like Brompton, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. There are hotels and other places to stay in and around Brompton. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a building such as Brompton-Westbrook Primary School, service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Chatham station? Then any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Brompton Garrison Church, service openings in its walls need the right fire-rated sealant, as in any building.

Brompton questions
Can you help a landlord with a rental near Chatham station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you take on hotel work around Brompton?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you work in Brompton?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Where do you work from?
Mr Mastic is based in Crawley. We cover Brompton and the rest of Medway, along with the rest of our area.
How much does fire rated sealant cost in Brompton?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you certify the fire stopping?
Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
Surface by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.
What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. For a job in Brompton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Keep pets and children clear of the area while we work

Advice
What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Homes in smaller places like Brompton can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.
