Commercial buildings in Highbridge
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 Mary's Church, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Colden Common Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Fire rated sealant in Highbridge, done properly
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. We work on linear gaps, pipe & cable gaps and flats & HMOs, and common reasons people get in touch are sealant items on a fire risk assessment action list and linear gaps at the head of walls.
For holiday lets, converted business premises or a community building near Highbridge, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach.
Signs you need fire rated sealant in Highbridge
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Any of these means the joints need attention:
- Open holes round services passing through fire walls
- Gaps filled with a product that isn’t fire-rated
- Seals cut through by electricians, plumbers or data installers
- Unsealed gaps around fire door frames
For landlords with property near Eastleigh station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions from Highbridge
Is Highbridge in your area for fire rated sealant?
Yes. We work across London and the South East, and Highbridge is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.

Where is Mr Mastic based?
We work from Crawley. We cover Highbridge and the rest of Hampshire, along with the rest of our area.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How much does fire rated sealant cost in Highbridge?
Size, access and the old material all affect the cost. Ask us for a quote.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What does intumescent mean?
Intumescent means it swells when heated to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ask which product was used before you paint
- Take pictures of fire stopping before ceilings or boxing go back
- File the fire-stopping record where your assessor can find it
- Tell trades working in the building that fire seals must be put back
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Highbridge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Before we arrive
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Construction that doesn’t provide fire resistance on its own
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Plasterboard & masonry
- Service penetrations
- Pipe & cable gaps
- Flats & HMOs
- Door frames
- Linear gaps
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
