What the job involves on each 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
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.
How we handle fire rated sealant in Brentham Garden Suburb
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have open gaps behind door architraves and holes left by a change of layout, we can help.
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 Brentham Garden Suburb, and room-by-room programmes can be planned where needed.
All our work comes with a one-year guarantee, wherever you are in Greater London.

Aftercare tips
After the cure time, these simple habits help:
- Ask which product was used before you paint
- Keep photos of seals that will be hidden
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Include hidden areas like risers in routine checks
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
What we’re called out for in Brentham Garden Suburb
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
If you can see any of these, it’s time to have the joints looked at:
- Sealant items on a fire risk assessment action list
- Holes left by a change of layout
- Damaged fire sealant left by other trades
- Gaps filled with a product that is not fire-rated
As a London address, Brentham Garden Suburb can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What fire rated sealant looks like in Brentham Garden Suburb
There are hotels and other places to stay in and around Brentham Garden Suburb. Hotel work can be planned room by room, with out-of-hours working where needed. 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as St Gregory's Catholic Primary School, fire-stopping around service openings should be restored whenever new services go in. Rented homes near Ealing Broadway station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Why it’s worth doing now in Brentham Garden Suburb
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

What to tell us for a quote

- Access, such as stairs, a lift or height

- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or email us with the details.
How it works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In Brentham Garden Suburb, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints

Questions from Brentham Garden Suburb
Do you take on hotel work around Brentham Garden Suburb?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near Ealing Broadway station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you certify the fire stopping?
We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
