About our fire rated sealant in Compton
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on flats & HMOs, door frames and pipe & cable gaps, and people most often call us about unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall.
If you have holiday lets, a converted barn used for business or a community building near Compton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Each job carries a 12-month guarantee, whatever its size.

Compton: your questions answered
Do you cover smaller places like Compton?
Yes, Compton is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do fire rated sealant in Compton?
Yes. Our work covers London and the South East, and Compton is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on how many gaps there are. We will confirm how long when we quote.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Get damaged fire seals looked at promptly
- Keep photos of seals that will be hidden
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask every contractor to reseal any fire stopping they disturb
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Compton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Quotes for fire rated sealant in Compton
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- Working hours on commercial sites
- The product the joint needs
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What we need to know
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- Where the job is, and your postcode
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Why deal with it now?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Compton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
Why choose Mr Mastic in Compton
- Anti-fungal silicone where joints get wet

Different surfaces, different methods
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified room by room.
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.
What sealant work can’t fix
We won’t take on work that won’t last, so these are the limits:
- A wall that is not a fire-resisting element to begin with
- Deciding what fire stopping a building needs
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Door frames
- Service penetrations
- Flats & HMOs
- Plasterboard & masonry
- Linear gaps
- Pipe & cable gaps

Signs you need fire rated sealant in Compton
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Any of these means the joints need attention:
- Gaps left after a refit or conversion
- Fire stopping disturbed by later work
- Unsealed gaps where pipes and cables go through a wall
- Gaps where walls meet ceilings or slabs
If you look after a building such as Compton C.E. Primary School, fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before booking
- Whether they’re fully insured
- Which colour the sealant will be
- Who does the work, and how experienced they are
- How long the guarantee is
Commercial buildings in Compton
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a church, hall or community building such as Church of St Mary and St Nicholas, gaps around pipes and cables are worth checking after any building work there.
