Fire stopping for Tokyngton sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Planning a London job such as one in Tokyngton starts with access. Send the building rules and access times with your enquiry.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Confirm the product named in the specification
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Advice
Fire stopping in Tokyngton
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. The enquiries we see most involve seals that don’t match their tested detail and open linear gaps along the top of fire-resisting walls, on pipe penetrations, cable penetrations and linear gaps at wall heads. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tokyngton is the same: 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. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Tokyngton
Could you schedule work at a campus like University of West London for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Do you work in Tokyngton?
Yes. Sites across Tokyngton are covered, with one number for every area we cover.
Is BS 476 being phased out?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook, with clause 2.1.14 covering service penetrations.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Check with the data sheet before painting over fire sealant
- Check risers and ceiling voids after each round of works
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Keep general-purpose fillers away from compartment walls
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
Fire stopping in Tokyngton: the local picture
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. 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.
For a site team at a college like Regent College, 0.8 miles to the west of Tokyngton, fire-rated sealing is best scheduled after the summer works. For a unit at a site such as Wembley Stadium Industrial Estate (0.8 miles north of Tokyngton), new power or data runs between office and warehouse can breach a compartment wall.
Tokyngton is about 1 mile south-east of Wembley, in Greater London. Anywhere in HA9, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 764 places across Greater London fall within our area, including Tokyngton. We also cover London, some 9 miles away.

When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Fire doors, dampers or other fire safety equipment
- Openings that need collars, wraps, batts or boards rather than sealant
- Construction that lacks the fire resistance the seal relies on
If in doubt, ring 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
General trades versus a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Surface by surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and any bundle too large for sealant alone is flagged.
Other services in Tokyngton
What we are called out for in Tokyngton
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Typical triggers for a call:
- Unsealed joints where partitions meet the slab
- Seals that don’t match their tested detail
- Penetration schedules that need working through
- Builders’ foam or ordinary silicone in compartment walls
Shop fits in centres such as Stadium Retail Park, 1 mile to the north of Tokyngton, can bring new services through fire-resisting walls between units, which then need the specified seal.
