About our fire stopping in Kensal Green
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. Where there isn’t one, the designer or fire engineer needs to set one first. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are fire sealant pulled out of the opening and fire-stopping items raised at inspection or handover. One point of contact handles commercial sealant work in Kensal Green from the first photos to the final walk-round, for single jobs and planned programmes alike.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Penetration seals near Kensal Green
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
At a university such as Imperial College London, 1.1 miles south of Kensal Green, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Colleges such as St Charles Catholic Sixth Form College (to the south-east of Kensal Green) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

What affects the price in Kensal Green
The price varies from site to site. Expect it to depend on:
- Phasing around occupants
- Backing rod, priming and other preparation
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Clear photos of the problem areas
- Any dates the work must fit around
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Questions we’re asked in Kensal Green
Can work at a site such as Imperial College London fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you seal around new services in a hotel near Kensal Green?
Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Kensal Green, access comes first. Send the building rules and access times with your enquiry.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
- Move anything stored against the joints
Request a quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Advice
When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Walls or floors that aren’t fire-resisting to begin with
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.
Joints and surfaces we work on
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads

What else we do in Kensal Green
For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Kensal Green can form part of a wider programme.
Common problems we fix in Kensal Green
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Look out for the following:
- Damaged fire seals in risers and voids
- Unsealed openings around new pipes and cables
- Fire-rated sealant that has cracked or shrunk back
- Penetration schedules that need working through
On estates like Mitre Bridge Industrial Estate, 0.5 miles to the south-west of Kensal Green, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
