Fire stopping for commercial buildings in Kemsley Street
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, not a rule of thumb. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the usual reasons a site gets in touch are open linear gaps along the top of fire-resisting walls and openings left by services added after handover. A single leaking joint is often how a building in Kemsley Street first comes to us: we look at the rest while we are there and tell you what we find.
Barn and farm-building conversions near places like Kemsley Street often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Keep product data and details in the fire safety file
- Brief every trade that openings they make must be sealed
- Get seals inspected before ceilings and boxing close
- Keep general-purpose fillers away from compartment walls
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. It tells the next contractor exactly what to reinstate, and it helps at inspections.
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What the job involves on each surface
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we’ll tell you what the detail says instead.
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
Questions about Kemsley Street
What does the BS 476 change mean for fire-rated sealant in Kemsley Street?
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.
Is hospital work, at somewhere like Spire Alexandra Hospital, something you do?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can you quote from photographs?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Halls, stores and units around places like Kemsley Street may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Fire stopping around Kemsley Street: what changes locally
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 32 miles from Kemsley Street. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
In a school such as Deanwood Primary School, fire-rated sealant goes in around service penetrations where it is specified. At a retail site such as Hempstead Valley Shopping Centre, 0.9 miles north-west of Kemsley Street, walls between units may be fire-resisting, so services added in a refit need the specified seal. For a building such as Church of St Peter, new heating or data runs are the usual reason penetrations need sealing.

What else we do in Kemsley Street
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- The site’s rules and procedures
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
Sending details for a quote
However big the job, these details speed things up:
- The product your specification calls for
- The asbestos register, for older buildings
- Where the site is, with the postcode
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. For work around Kemsley Street, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- 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.
- 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.
What we need from you
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
- Agree which areas must stay open
