Fire stopping for Kilburn sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Don’t let anyone top up a fire seal with the wrong product
- Arrange inspection before areas are covered up
- Flag new cables with no seal around them
- Include service cupboards in routine inspections
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
About our fire stopping in Kilburn
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. The enquiries we see most involve unsealed openings around new pipes and cables and fire-stopping items raised at inspection or handover, across joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows. Looking for mastic applicators who cover Kilburn? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Fire stopping around Kilburn: what changes locally
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We seal to the specification and the product’s tested detail, working within the building’s permits. Plenty of hotels sit less than 2 miles from Kilburn. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
In a retail centre such as O2 Centre, 1.2 miles north-east of Kilburn, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. For a site team at a college like City of Westminster College, 0.8 miles south-east of Kilburn, fire-rated sealing is best scheduled after the summer works. Residences at universities like Imperial College London (to the south-west of Kilburn) have compartment walls that must be resealed whenever services change.
Kilburn is about 3 miles north-west of City of Westminster, in Greater London. If you’re looking for fire stopping in Kilburn, we can help, as we do across Greater London. Kilburn is one of 764 places in Greater London on our list.

Questions about Kilburn
Can you work around term dates at a campus such as Imperial College London?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
How long does a typical visit take?
It depends on the scope, but the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What will the job cost?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
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 is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Gaps in walls that were never built as compartment walls
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire risk assessments, a job for a competent assessor
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
What affects the price in Kilburn
We price every job individually. The main factors are:
- The size and state of each joint
- Whether old sealant has to be cut out first
- Working within restricted access windows
- Site requirements such as inductions and permits
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Access details, including height
- Specification clauses that apply
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Work for main contractors and building owners
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements

Why it’s worth doing now in Kilburn
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. In Kilburn, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
