Fire rated sealant in Kensal Green, done properly
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for new service routes left unsealed after building work and gaps filled with a product that isn’t fire-rated, across linear gaps, plasterboard & masonry and flats & HMOs.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Kensal Green can’t close.
Our work is backed for twelve months.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Photograph sealed gaps before they’re covered up
- Plan fire stopping into any work that goes through walls or floors
- File the fire-stopping record where your assessor can find it
- Ask which product was used before you paint
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Kensal Green questions
Can parking be tricky for a visit in Kensal Green?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Can you help a landlord with a rental near Kensal Green station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door, its seals and closer are for a door specialist.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Quotes for fire rated sealant in Kensal Green
There’s no set price list, because no two jobs are the same. The quote depends on:
- The product the joint needs
- How easy the joints are to reach
- Any mould that needs treating
- The amount of work
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- The address or postcode of the job
- Whether it’s a home or a business
- Pictures of the joints, sent by email
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
- Construction that does not provide fire resistance on its own
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

What we’re called out for in Kensal Green
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
The problems people usually mention when they call include:
- Sealant items on a fire risk assessment action list
- Damaged fire sealant left by other trades
- Ordinary sealant used where a fire-rated product was needed
- Fire seals that have cracked with movement
For landlords with property near Kensal Green station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

- How the joint is cleaned and prepared
- How long the guarantee is
