Honest limits
We check first that sealant really is the fix. It won’t put right:
- Openings that need collars, wraps, batts or boards rather than sealant
- Deciding what a wall or floor needs, which belongs to the designer
- Fire risk assessments, a job for a competent assessor
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
What we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
How we handle fire stopping in North Kensington
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you are dealing with seals that don’t match their tested detail and head-of-wall gaps with no fire seal, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in North Kensington it comes down to the same thing: the right product in a properly prepared joint.
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 our installation lets you down in that time, we return and fix it.

Compartments and services around North Kensington
The area within 2 miles of North Kensington holds a good number of hotels. 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. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
Industrial units on estates such as Latimer Industrial Estate, 0.5 miles south-west of North Kensington, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. In a retail centre such as Kensington Arcade, 2 miles south-east of North Kensington, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Theatres, wards and plant rooms at sites like St Charles' Hospital (under half a mile south-east of North Kensington) all have compartment walls crossed by services.
North Kensington is about 2 miles north-west of Kensington, in Greater London. We send applicators to North Kensington for service penetrations, handled exactly as we handle every other area. North Kensington is one of 764 places we cover in Greater London. We also cover London, some 6 miles away.

Why it’s worth doing now in North Kensington
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Failed sealant in a building in North Kensington can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Quoting for work in North Kensington
The price varies from site to site. It mainly depends on:
- Access and working height
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
Pricing service penetrations depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.
What we need to price the job
A few photographs plus some basic facts will normally do. It helps to include:
- The product your specification calls for
- Asbestos survey details if the building is older
- Access details, including height
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Building owners, agents and FMs in North Kensington
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
