Fire stopping in Low Street, done properly
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve snag lists that include open service penetrations and openings left by services added after handover, on joints between fire-resisting walls and floors, cable penetrations and service gaps in risers.

Rural conversions around Low Street can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the quote is worked out
Before we quote, we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Travel to remote or island sites
- Joint width, depth and condition
- Any access equipment needed
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
However big the job, the same details help:
- Anything awkward about access or site hours
- When you need the work done
- Approximate linear metres or a joint schedule
- The postcode of the building
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or use the quote form to discuss it first.
Leave it or put it right?
Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Halls, stores and units around places like Low Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Why appoint us
- Fixed quotes based on photographs, drawings or a visit
- Constructionline member for supplier checks
- 12 months’ guarantee on every job
- Old sealant cut out, never sealed over

Fire stopping in Low Street: the local picture
Central London is about 21 miles from Low Street. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
Older community buildings such as St James' Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a unit at a centre such as Imperial Retail Park, which lies south-west of Low Street, penetration seals are worth checking after each shop fit. Workshops and IT rooms at colleges like USP College, 2.2 miles west of Low Street, are re-serviced often, leaving penetrations to seal.

On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Low Street may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Let building users know which areas are affected
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000

Advice
What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables.
Common questions from Low Street clients
Will you work in a care home in Low Street without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Is Thames Industrial Park, near Low Street, within your area?
Yes. We cover Low Street and the area around it, including industrial estates, business parks and retail parks such as Thames Industrial Park. Photos and a short description are enough for a first look.
Do you approve fire stopping for building control?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Aftercare for building managers
For the best life from the joints:
- Report damaged or disturbed seals as soon as they’re spotted
- Agree the fire-stopping specification before services go in
- Look above ceilings when tiles are lifted for other jobs
- Get seals inspected before ceilings and boxing close
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
