Common problems we fix in Chatham Green
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Common reasons buildings call us in:
- Unsealed openings around new pipes and cables
- Non-fire-rated filler around services
- Fire sealant pulled out of the opening
- Unsealed joints where partitions meet the slab
At a university such as Anglia Ruskin University (5 miles south of Chatham Green), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

How we handle fire stopping in Chatham Green
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. Those on your schedule are closed with the specified product. The enquiries we see most involve non-fire-rated filler around services and seals disturbed by maintenance and left open, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. For commercial sealant work in Chatham Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Chatham Green often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Questions we’re asked in Chatham Green

Do you cover business parks and estates near Chatham Green, such as Banters Lane Business Park?

Is the BS 476 change in 2029 relevant to fire stopping?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. Scotland follows its own Technical Handbook.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email the details over. Include photographs or drawings if you have them.
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 if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
From enquiry to sign-off
When we get to site, 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 typically taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Rural sites near Chatham Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Share the asbestos register for older buildings
- Point out any areas we must not close
- Let building users know which areas are affected

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email us.
Advice
What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Older rural buildings around Chatham Green move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Walls or floors that aren’t fire-resisting to begin with
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.
Joints and surfaces we work on
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
Different surfaces, different methods
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.
Compartments and services around Chatham Green
In England, Approved Document B covers fire stopping of 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. What we install is set by the specification, and it goes in to the tested detail. Central London is about 33 miles from Chatham Green. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
For a hospital such as Broomfield Hospital, 2.9 miles south of Chatham Green, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. In a building such as Church of St John the Evangelist, any service penetration through a fire-resisting wall should be sealed to the specified detail.
