Fire rated sealant in Borough Green, done properly
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on door frames, plasterboard & masonry and linear gaps, and the jobs we see most are linear gaps at the head of walls and fire stopping disturbed by later work.
Community buildings, schools and small businesses around places like Borough Green have washrooms and kitchens that see a lot of use. Their sealant and fire-rated joints are as important as those in any bigger building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Include hidden areas like risers in routine checks
- Tell trades working in the building that fire seals must be put back
- Store the list of sealed gaps with your building paperwork
- Report cracked or damaged seals as soon as you notice them
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
When it isn’t the sealant
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
- Assessing a building’s fire safety
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. A visit to Borough Green is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Advice
Why act early in Borough Green
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Homes in smaller places like Borough Green can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Commercial buildings in Borough Green
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, 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.
For site and facilities teams at buildings such as Borough Green Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like The Church of the Good Shepherd are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What the job involves on each surface
Door frames
Frame gaps are usually hidden behind the architrave. We seal any open gap to the product’s tested details before the trim goes back.
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 and we will flag it.
