Fire stopping for businesses in Gomshall
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Fire stopping in Gomshall
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 non-fire-rated filler around services and unsealed joints where partitions meet the slab, across joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. A single leaking joint is often how a building in Gomshall first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places like Gomshall, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job we finish is backed by a 12-month workmanship guarantee, in Gomshall as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Site requirements such as inductions and permits
- The total length or number of joints
- Backing rod, priming and other preparation
- Travel to remote or island sites
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Your programme or deadline
- Any specification or named product
- Drawings or a marked-up plan, if available
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email the details over.

How the job changes by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Gomshall, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Send any specification or drawings in advance
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints

When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Gaps in walls that were never built as compartment walls
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
Why it’s worth doing now in Gomshall
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Around Gomshall, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.

Compartment walls and floors in Gomshall
For England, the fire stopping of penetrations is dealt with in 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. Gomshall lies roughly 25 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
For a school such as Shere CofE Aided Infant School, penetration sealing fits best at the end of the summer works. Older community buildings such as The Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Large healthcare estates like St. Luke’s Hospital (to the west of Gomshall) change their services often, so penetration seals are worth checking after M&E work.
