Fire rated sealant in Sewardstone, done properly
We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. Typical jobs include unsealed gaps where pipes and cables go through a wall and fire seals that have cracked with movement, on door frames, service penetrations and linear gaps.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, 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 Sewardstone can’t close.
There’s a 12-month guarantee on every job, large or small.

Honest limits
A few problems are outside what sealant work can do:
- A wall that isn’t a fire-resisting element to begin with
- Certifying a building or signing off its fire safety
- Deciding what fire stopping a building needs

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why act early in Sewardstone
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Can parking be tricky for a visit in Sewardstone?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

How much does fire rated sealant cost in Sewardstone?

Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
How long does the job take?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before work begins. The work usually takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Sewardstone. A visitor permit or a nearby bay makes the visit run more smoothly.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on

How the job changes by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the seal has something sound to bond to.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Workplaces and buildings in Sewardstone
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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.
Letting a property close to Enfield Lock station? Then any gap left by new services in shared walls should be closed with a fire-rated product. As a London address, Sewardstone can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Common reasons people contact us include:
- Gaps filled with a product that is not fire-rated
- Cracked or shrunken fire-rated sealant
- Unsealed gaps where pipes and cables go through a wall
- Gaps where walls meet ceilings or slabs
Schools such as Prince of Wales Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
