Surface by surface
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
About our fire rated sealant in Wiston
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have seals cut through by electricians, plumbers or data installers and standard silicone or caulk in a fire-stopping gap, we can put it right.
Somewhere as small as Wiston, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Common problems we fix in Wiston
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Keep an eye out for these signs:
- Gaps where walls meet ceilings or slabs
- Seals cut through by electricians, plumbers or data installers
- Ordinary sealant used where a fire-rated product was needed
- Unsealed gaps where pipes and cables go through a wall
If you look after a church, hall or community building such as All Saints Church, gaps around pipes and cables are worth checking after any building work there.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Large holes that need a different fire-stopping system
- Walls or floors that weren’t built to resist fire
- Doors that are not fire doors in the first place
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What else we do in Wiston
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. For a village or hamlet like Wiston, 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.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky

Related advice
Why it’s worth doing now in Wiston
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Older cottages and farmhouses around Wiston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
