Fire rated sealant for homes and businesses in Thornton
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on door frames, service penetrations and plasterboard & masonry, and common reasons people get in touch are linear gaps at the head of walls and unsealed gaps where pipes and cables go through a wall.
If you look after holiday lets, a guest house or a community building in or near Thornton, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
Each job carries a 12-month guarantee, whatever its size.

Why deal with it now?
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 Thornton, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

FAQs for Thornton
Do you work for landlords with property near Glenrothes with Thornton station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Are the rules for fire-rated sealant different in Scotland?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.
What fire rating will the seal have?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.
Do you come to Thornton?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Thornton included.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Get damaged fire seals looked at promptly
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Ask every contractor to reseal any fire stopping they disturb
- Check whether a sealant can be painted before decorating over it
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.

Advice
DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Common problems we fix in Thornton
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Most people get in touch after spotting one of these:
- Gaps filled with a product that isn’t fire-rated
- Gaps where walls meet ceilings or slabs
- Unsealed gaps where pipes and cables go through a wall
- Holes left by a change of layout
For buildings such as Old Parish Church, service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before booking
- What insurance they hold
- Whether they seal over old material or remove it
- When the joint can take water or movement
- How hidden problems are handled
