About our fire rated sealant in Eastwood
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We are often asked to deal with seals cut through by electricians, plumbers or data installers and open gaps behind door architraves, on linear gaps, flats & HMOs and door frames.
Work in a small place like Eastwood is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Report cracked or damaged seals as soon as you notice them
- Store the list of sealed gaps with your building paperwork
- Photograph sealed gaps before they’re covered up
- Ask which product was used before you paint
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
What the job involves on each surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Questions from Eastwood
Is Eastwood in your area for fire rated sealant?
Yes, Eastwood is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work for landlords with property near Harrietsham station?
Yes. We work for landlords and letting agents as well as homeowners, 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’ll give you a clear quote.
Will we have a record of what was sealed?
Yes. We record the locations we have sealed and the products used.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We will give you a better idea when we quote.
What fire rating will the seal have?
We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service and we can apply it for you.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Commercial buildings in Eastwood
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
Managing a site like Ulcombe Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Everything for the job comes with us, so a second trip is avoided where possible.

- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.

Why it’s worth doing now in Eastwood
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a small place like Eastwood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What we are called out for in Eastwood
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave does not always get resealed.
These are the problems we are asked about most:
- Fire stopping disturbed by later work
- Linear gaps at the head of walls
- Gaps around pipes and cables through fire-resisting walls
- Old fire sealant that has split or come away
Letting a property close to Harrietsham station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
