Leave it or put it right?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around Nettlebed, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before we start.

Fire rated sealant for homes and businesses in Nettlebed
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. Those are the gaps we close, using a tested fire-rated product. Typical jobs include open joints along the top of partitions and gaps around pipes and cables through fire-resisting walls, on plasterboard & masonry, flats & HMOs and linear gaps.
In a village or hamlet like Nettlebed, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Nettlebed: your questions answered
Is Nettlebed within the area you cover?
Yes. Nettlebed is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you take on hotel work around Nettlebed?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building
- Problems with the door itself rather than the gap around the frame
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

What happens on the day
The work is kept neat and contained to the joints we are treating. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Nettlebed, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Landlords, agents and businesses in Nettlebed
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How to look after the new joints
To keep the joints looking good and working properly:
- Include fire stopping when you schedule refits
- Flag any open gap you spot round a pipe or cable
- Check whether a sealant can be painted before decorating over it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
What affects the quote in Nettlebed
Call for a quick quote. What matters most is:
- The type of sealant required
- The size of the job
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or send us an email.
Workplaces and buildings in Nettlebed
Nettlebed has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Church of St Bartholomew, older buildings that have had new heating or wiring often have service gaps worth checking.

It’s worth asking for a quote if you see:
- Linear gaps at the head of walls
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
- Gaps filled with a product that is not fire-rated
Schools such as Nettlebed Community School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
