Fire stopping in Kensal Rise
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you are dealing with openings found when ceilings come down for a refit and expanding foam used as fire stopping, we can put it right, whatever the surface. A single leaking joint is often how a building in Kensal Rise first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Kensal Rise clients
Do you work on fire-rated sealing in hotels in Kensal Rise?
Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Kensal Rise?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap
If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.
What we seal
- Joints between fire-resisting walls and floors
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep general-purpose fillers away from compartment walls
- Treat an open penetration as a priority repair
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask which product is in place before decorating
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For a job in Kensal Rise, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Have the specification and drawings to hand
- Move anything stored against the joints
- Flag any permit to work we’ll need

What we are called out for in Kensal Rise
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Any of the following is a good reason to get the joints checked over:
- Fire-rated sealant that has cracked or shrunk back
- Fire seals cut back for extra cables and never reinstated
- Fire-stopping items raised at inspection or handover
- Improvised or mixed-product fire seals
For a hospital such as St Charles' Hospital, 0.7 miles south of Kensal Rise, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Fire-rated sealing for Kensal Rise buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Kensal Rise holds plenty of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
For a building at a site such as The Quadrant Business Centre, 0.6 miles to the north-east of Kensal Rise, a check of penetration seals after each fit-out is good practice. For a site team at a college like Morley College London (0.8 miles south-east of Kensal Rise), fire-rated sealing is best scheduled after the summer works.
Kensal Rise is about 1 mile south-west of Kilburn, in Greater London. Looking for fire stopping in Kensal Rise? We can help. 764 places across Greater London fall within our area, including Kensal Rise. Our London page has more on work in that area, about 6 miles away.
Work on service penetrations is covered throughout W10, NW10 and NW6, for business premises of every kind. Buildings on Hazel Road, Hiley Road and Kempe Road are within our area.

Local landmarks in Kensal Rise
Recent enquiries here include premises near Paradise by Way of Kensal Green pub, Queens Park Community School and Brondesbury College and the streets around them. Kensal Rise has its own railway station: Kensal Rise station. Other landmarks nearby include Brent Museum and Archives (1.1 miles north-west) and Westfield London (1.8 miles south). Not far away are The Long Water and Campden Hill.
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
