Fire rated sealant in Foulford, done properly
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you’re dealing with damaged fire sealant left by other trades and gaps left after a refit or conversion, we can help, whatever the surface.
For holiday lets, converted business premises or a community building near Foulford, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
A one-year guarantee comes as standard.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Foulford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- 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.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

Signs it’s time to call us include:
- Open holes round services passing through fire walls
- Door frames with gaps between frame and wall
- Holes left by a change of layout
- Gaps filled with a product that isn’t fire-rated

FAQs for Foulford
Is Foulford in your area for fire rated sealant?
Yes. We work across London and the South East, and Foulford is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is fire rated sealant in Foulford guaranteed?
All our work, in Foulford and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
What information do you need?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Assessing a building’s fire safety
- Issuing a fire rating or certificate for a building
- Big openings where sealant alone is not the tested solution
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

How to look after the new joints
Looking after new joints is easy:
- Flag any open gap you spot round a pipe or cable
- Ask every contractor to reseal any fire stopping they disturb
- Do not paint over fire sealant until it has cured
- Never patch a fire seal with standard sealant
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What fire rated sealant looks like in Foulford
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 work to the specification you’re given, installing the product to its tested details.
Community buildings like St John the Baptist are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Why deal with it now?
Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again once someone inspects it. Around Foulford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
