Why act early in Poyle
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. Around Poyle, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before work begins.

About our fire rated sealant in Poyle
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. If you have gaps where walls meet ceilings or slabs and gaps filled with a product that isn’t fire-rated, we can help, on flats & HMOs, pipe & cable gaps and service penetrations alike.
For holiday lets, converted business premises or a community building near Poyle, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Different surfaces, different methods
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Landlord and commercial work in Poyle
For anyone letting property in or around Poyle, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of gaps, and longer for a whole building from start to finish. In a small place like Poyle, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Advice
Do you need fire rated sealant in Poyle?
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
The problems people usually mention when they call are:
- Open gaps behind door architraves
- Fire seals that have cracked with movement
- New service routes left unsealed after building work
- Linear gaps at the head of walls
If you look after a church, hall or community building such as Church of St Thomas, gaps around pipes and cables are worth checking after any building work there.
What to look for in a quote
- Whether you can choose the colour
- How long to leave it before use
- What happens if the job turns out different
- What guarantee comes with the work
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Fire doors that need new seals, closers or hardware
- A wall that isn’t a fire-resisting element to begin with
- Sign-off of the building, which sits with building control or your assessor
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
