Fire rated sealant in Burgess Hill
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on door frames, plasterboard & masonry and linear gaps, and the jobs we see most are unsealed gaps around fire door frames and old fire sealant that has split or come away.
Shared washrooms take far more use than a home bathroom, and their sealant shows it, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Burgess Hill, timings are planned around the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why act early in Burgess Hill
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Burgess Hill they get worse with every use. Now is the easy time to put it right.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

How long does the job take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Fire rated sealant in Burgess Hill: local notes
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.
If you let a flat or house near Burgess Hill station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as St John the Evangelist's Church, service openings in its walls need the right fire-rated sealant, as in any building.

When to call us in Burgess Hill
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
These are the problems we are asked about most:
- Damaged fire sealant left by other trades
- Holes left by a change of layout
- Joints picked up in a fire-stopping survey
- Gaps around pipes and cables through fire-resisting walls
For site and facilities teams at buildings such as St Wilfrid's Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- What happens if the job turns out different
- Whether they seal over old material or remove it
- Which colour the sealant will be
- How much experience the applicator has

Door frames
Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
