What the job involves on each surface
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.
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
How we handle fire rated sealant in South Wimbledon
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on flats & HMOs, service penetrations and door frames, and common reasons people get in touch are gaps where walls meet ceilings or slabs and fire stopping disturbed by later work.
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 South Wimbledon, and room-by-room programmes can be planned where needed.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Fire rated sealant around South Wimbledon
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
As a London address, South Wimbledon can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Wimbledon station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Holy Trinity are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How the visit works
We keep the work tidy and contained to the area we are working on. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. In a London area like South Wimbledon, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Before we arrive
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

South Wimbledon questions
Do you take on hotel work around South Wimbledon?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can parking be tricky for a visit in South Wimbledon?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Are you insured?
Yes, we’re fully insured for every job we do.
How much does fire rated sealant cost in South Wimbledon?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email with a short description of the job.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Why act early in South Wimbledon
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in South Wimbledon.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before work begins.

What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Assessing a building’s fire safety
- Large holes that need a different fire-stopping system
- Doors that are not fire doors in the first place
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
