Fire rated sealant in Chalk Farm
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on linear gaps, pipe & cable gaps and service penetrations, and the jobs we see most are unsealed gaps around fire door frames and fire stopping disturbed by later work.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Chalk Farm, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Other services in Chalk Farm
Different surfaces, different methods
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.
The process
The work is kept neat and contained to the area we are working on. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- 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.
- We hand over a list of locations and products for your records.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Advice
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
If you manage several properties in or around Chalk Farm, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Workplaces and buildings in Chalk Farm
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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Community buildings like St Silas Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Kentish Town West station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Haverstock School? Then fire-stopping around service openings should be restored whenever new services go in.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Photograph sealed gaps before they’re covered up
- Plan fire stopping into any work that goes through walls or floors
- Make resealing part of every contractor’s brief
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
- Issuing a fire rating or certificate for a building

Chalk Farm questions
Do you work for hotels and guest houses in Chalk Farm?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you help a landlord with a rental near Kentish Town West station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you come to Chalk Farm?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Chalk Farm.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.
How much does fire rated sealant cost in Chalk Farm?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Do you provide details of the products used?
Yes. We note each location and the product that went in, so you have it on file.
