Common call-outs are for old fire sealant that has split or come away and joints picked up in a fire-stopping survey, across linear gaps, flats & HMOs and plasterboard & masonry.

Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a smaller place like Boyatt Wood, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Do you take on fire stopping in schools and offices?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can you give us a record of the work?
Yes. You get a list of where we worked and what we used.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Boyatt Wood, along with the rest of our area.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.
What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. Parking around Boyatt Wood is usually 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.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
How to prepare
- Mention any tricky access
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

How we quote for fire rated sealant
You’ll get a clear quote before we start. It takes into account:
- Whether old sealant or filler has to be cut out

When to call us in Boyatt Wood
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
If you can see any of these, it’s time to have the joints looked at:
- Gaps around pipes and cables through fire-resisting walls
- Old fire sealant that has split or come away
- Joints picked up in a fire-stopping survey
- Door frames with gaps between frame and wall
Schools such as Crestwood Community School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
What your quote should include
- How hidden problems are handled
- Are they insured?
- Whether all the old sealant comes out first
- What the cure time is
When it is not the sealant
We’ll always be straight with you, so here’s what sealant can’t fix:
- Large holes that need a different fire-stopping system
- Certifying a building or signing off its fire safety
- Walls or floors that weren’t built to resist fire
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
- Pipe & cable gaps
- Service penetrations
- Flats & HMOs

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Plan fire stopping into any work that goes through walls or floors
- Ask which product was used before you paint
- Photograph sealed gaps before they’re covered up
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
Commercial buildings in Boyatt Wood
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 St. Peter's Church, older buildings that have had new heating or wiring often have service gaps worth checking.
