Northolt Fire Rated Sealant
Fire-stopping gaps in Northolt need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Gaps filled with a product that isn’t fire-rated
- Gaps around pipes and cables through fire-resisting walls
- Linear gaps at the head of walls
Fire rated sealant for homes and businesses in Northolt
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you have standard silicone or caulk in a fire-stopping gap and unsealed gaps where pipes and cables go through a wall, we can put it right, whatever the surface.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Northolt.
All our work comes with our one-year guarantee.

Fire rated sealant around Northolt
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged 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.
Managing a site like Willow Tree Primary School? Then fire-stopping around service openings should be restored whenever new services go in. As a London address, Northolt can be tricky for parking: let us know about parking bays, permits or a driveway.

Well-known places in the area include Heath Robinson Museum (3.1 miles north) and Clementine Churchill Hospital (2 miles north-east). Not far away are Islip Manor Meadows and Northala Fields.
Keeping the joints in good condition
So the new joints stay in good condition:
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
- File the fire-stopping record where your assessor can find it
- Keep photos of seals that will be hidden
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Northolt: your questions answered
Can you do fire rated sealant in Northolt?
Yes. We work across London and the South East, and Northolt is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Can you help a landlord with a rental near Northolt Park station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What should I tell you?
A short description and the location. If we need more, we will ask.
Will you assess my building’s fire safety?
No. We follow the requirements from your assessor, designer or building control.
Why it’s worth doing now in Northolt
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. In a flat in Northolt, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- Rated 4.9 stars on Google
- 20+ years of sealant experience
- Experience in homes, commercial sites and hotels

What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Northolt. A visitor permit or a nearby bay makes the visit run more smoothly.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Before we arrive
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Signs you need fire rated sealant in Northolt
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Most people get in touch when they notice one of these:
- New service routes left unsealed after building work
- Open joints along the top of partitions
- Cracked or shrunken fire-rated sealant
- Gaps flagged on a fire risk assessment
Community buildings like St Richard's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before booking
- When the joint can take water or movement
- What happens if the job turns out different
- Is VAT in the price?
- Which colour the sealant will be
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’ll flag it.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.
