Fire rated sealant in Glassenbury
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Common call-outs are for ordinary sealant used where a fire-rated product was needed and cracked or shrunken fire-rated sealant, across flats & HMOs, service penetrations and pipe & cable gaps.
For holiday lets, converted business premises or a community building near Glassenbury, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
We stand behind the work with a 12-month guarantee.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
- Openings too large for sealant, which need batts, boards or another system
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

What else we do in Glassenbury
Common problems we fix in Glassenbury
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Fire stopping disturbed by later work
- Gaps flagged on a fire risk assessment
- Open holes round services passing through fire walls
- Door frames with gaps between frame and wall
For site and facilities teams at buildings such as High Weald Academy, service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before you book
- What guarantee comes with the work
- Is VAT in the price?
- Whether you can choose the colour
- Who turns up on the day
Leave it or put it right?
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. In a small place like Glassenbury, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Advice
Glassenbury questions
Is there a guarantee on fire rated sealant in Glassenbury?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Glassenbury within the area you cover?
Yes. Glassenbury is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take on fire stopping in schools and offices?
Yes. Occupied flats, HMOs, offices and schools are all fine. Out-of-hours work can be arranged.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How the job changes by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
