About our fire stopping in Sheet
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. 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 fire-stopping items raised at inspection or handover and unsealed penetrations discovered above suspended ceilings, on joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Sheet first comes to us: we look at the rest while we’re there and tell you what we find.
A job near Sheet is typically planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
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.
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.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Walls or floors that aren’t fire-resisting to begin with
- Fire risk assessments, a job for a competent assessor
- Large openings beyond what any sealant detail covers
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
Surfaces we seal
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
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.
Metal pipes
Heat travels along metal pipework, and some details add wrapping or a set length of insulation. We follow whatever the detail requires and flag anything we can’t match.
Our process
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Sheet are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close

Advice
Common problems we fix in Sheet
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.
Typical triggers for a call:
- Improvised or mixed-product fire seals
- Fire seals cut back for extra cables and never reinstated
- Snag lists that include open service penetrations
- Openings left by services added after handover
Schools such as Sheet Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What else we do in Sheet
Why deal with it now?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. For buildings around smaller places like Sheet, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Fire stopping in Sheet: the local picture
At about 49 miles from central London, Sheet is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. In England, Approved Document B covers fire stopping of openings and penetrations. 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.
Halls and meeting rooms at places like Church of St Mary Magdalene sometimes gain new services, and any compartment wall crossed needs the specified seal. For a unit at a site such as Upper Adhurst Industrial Park (1 mile north-east of Sheet), new power or data runs between office and warehouse can breach a compartment wall.
