Fire rated sealant in Midanbury
Deciding which gaps need fire stopping isn’t our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for linear gaps at the head of walls and unsealed gaps around fire door frames, across flats & HMOs, service penetrations and linear gaps.
Community buildings, schools and small businesses around places like Midanbury have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Will you come out to Midanbury?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Doors that are not fire doors in the first place
- Large holes that need a different fire-stopping system
- Construction that doesn’t provide fire resistance on its own
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
What we seal
- Flats & HMOs
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Door frames
- Plasterboard & masonry
Different surfaces, different methods
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach and we’ll flag it.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Make resealing part of every contractor’s brief
- Report cracked or damaged seals as soon as you notice them
- Ask which product was used before you paint
- Take photos of fire stopping before ceilings or boxing go back
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Fire rated sealant in Midanbury: local notes
If you run a hotel, guest house or holiday let in a coastal place like Midanbury, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Ascension, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Bitterne Park School, gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Bitterne station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Related advice
Leave it or put it right?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. Around Midanbury, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email.
