Fire stopping for Withermarsh Green 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
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. If others near Withermarsh Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Tell us what induction or permit system the site runs
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand

How we handle fire stopping in Withermarsh Green
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about head-of-wall gaps with no fire seal and builders’ foam or ordinary silicone in compartment walls, across small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads. Searching for sealant specialists in Withermarsh Green? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Barn and farm-building conversions near places like Withermarsh Green 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Fire stopping of openings and penetrations in England falls under Approved Document B. 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.

After the work
Regular inspection catches problems early. Specifically:
- Flag new cables with no seal around them
- Keep product data and details in the fire safety file
- Arrange inspection before areas are covered up
- Check with the data sheet before painting over fire sealant
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. 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.
Different surfaces, different methods
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

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. Halls, stores and units around places like Withermarsh Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Common questions from Withermarsh Green clients
What does the BS 476 change mean for fire-rated sealant in Withermarsh Green?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.
Do you take on work at healthcare sites like Severalls Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
How much does the work cost?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email us.
Can staff carry on working while you’re here?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
