A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, gap by gap. We work on service penetrations, flats & HMOs and pipe & cable gaps, and people most often call us about holes left by a change of layout and joints picked up in a fire-stopping survey.
Work in a small place like Kingston Stert is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you certify the fire stopping?
Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Why it’s worth doing now in Kingston Stert
Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Older cottages and farmhouses around Kingston Stert can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Surface by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
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.

The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. For a village or hamlet like Kingston Stert, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Advice
When it isn’t the sealant
Before you book, it’s worth knowing the limits:
- Walls or floors that weren’t built to resist fire
- Assessing a building’s fire safety
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
- Do not paint over fire sealant until it has cured
- Keep general-purpose foam and caulk away from fire-stopping gaps
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Fire rated sealant in Kingston Stert: local notes
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, 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.
Schools such as Aston Rowant Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Princes Risborough station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of St Mary are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
