What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Approving the work on behalf of building control
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.

About our fire stopping in Bexleyheath
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. Those on your schedule are closed with the specified product. The enquiries we see most involve penetration schedules that need working through and unsealed openings around new pipes and cables, across service gaps in risers, small duct penetrations where the tested detail allows and pipe penetrations. For commercial sealant work in Bexleyheath, you deal with one contact from quote to sign-off, whether it’s one building or several.
In a London area such as Bexleyheath, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. In Bexleyheath, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready

Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Get seals inspected before ceilings and boxing close
- Report damaged or disturbed seals as soon as they’re spotted
- Don’t let anyone top up a fire seal with the wrong product
- Include service cupboards in routine inspections
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Where services cross fire walls in Bexleyheath
Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail. 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.
At a university such as University of Greenwich Avery Hill Campus, which lies west of Bexleyheath, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a hospital such as Erith and District Hospital, which lies north-east of Bexleyheath, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Offices at parks like Old Bexley Business Park (1.3 miles south-east of Bexleyheath) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Why act early in Bexleyheath
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. In Bexleyheath, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.

FAQs: Bexleyheath
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Would you work within a site like Erith and District Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is sealant suitable for all service openings?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do you work in Bexleyheath?
Yes. Sites across Bexleyheath are covered, and the same phone number covers every area.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
