Fire-rated sealant in Coombe, Buckinghamshire
Our applicators work in Coombe on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Joints picked up in a fire-stopping survey
- Gaps around pipes and cables through fire-resisting walls
- Linear gaps at the head of walls
What the job involves on each surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.
Fire rated sealant in Coombe, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We work on door frames, linear gaps and service penetrations, and common reasons people get in touch are door frames with gaps between frame and wall and gaps where walls meet ceilings or slabs.
Work in a small place like Coombe is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
Big or small, it’s backed by our one-year guarantee in Coombe and across Buckinghamshire.

When something else is needed
To be straight with you, some problems need a different trade:
- Large holes that need a different fire-stopping system
- Construction that doesn’t provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Keep photos of seals that will be hidden
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Include hidden areas like risers in routine checks
- File the fire-stopping record where your assessor can find it
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Fire rated sealant in Coombe: 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.
For site and facilities teams at buildings such as Great Kimble Church of England School, fire-stopping around service openings should be restored whenever new services go in. Rented homes near Little Kimble station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Peter and St Paul, service openings in its walls need the right fire-rated sealant, as in any building.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Coombe, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
