Wandsworth Fire Rated Sealant
Fire rated sealant across Wandsworth and nearby, with old sealant always removed completely and a 12-month guarantee.
- Open joints along the top of partitions
- Unsealed gaps where pipes and cables go through a wall
- Fire stopping disturbed by later work
What the job involves on each surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before applying the sealant.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.
About our fire rated sealant in Wandsworth
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. Typical jobs include standard silicone or caulk in a fire-stopping gap and holes left by a change of layout, on linear gaps, pipe & cable gaps and door frames.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Wandsworth, and room-by-room programmes can be planned where needed.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Wandsworth, the repair is bigger than the sealant job would have been.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Do you need fire rated sealant in Wandsworth?
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
The most common problems we see are:
- Gaps left after a refit or conversion
- Open gaps behind door architraves
- Old fire sealant that has split or come away
- Gaps around pipes and cables through fire-resisting walls
If you let a flat or house near Wandsworth Town station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Before you book anyone
- How long to leave it before use
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- Is the old sealant removed completely?
Wandsworth questions
Do you work in hotels near Wandsworth?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Will you assess my building’s fire safety?
No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used, so you have it on file.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
