Fire stopping in Chobham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle fire stopping in Chobham
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Chobham. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and unsealed penetrations discovered above suspended ceilings, across cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads. For commercial sealant work in Chobham, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Converted and extended buildings around places like Chobham can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Site staff or a sealant 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. 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 larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Fire stopping in Chobham: the local picture
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 24 miles from central London, Chobham is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For an estates team at a campus like Imperial College Silwood Park Campus, 4.5 miles to the north-west of Chobham, summer M&E works are normally followed by a round of penetration sealing. Theatres, wards and plant rooms at sites like Nuffield Health Woking Hospital (to the south-east of Chobham) all have compartment walls crossed by services.
Chobham is about 3 miles north-west of Woking, in Surrey. Businesses, contractors and managing agents in Chobham use us for work on service penetrations. Across Surrey, 379 places are covered, including Chobham. We also cover Reading, around 18 miles from Chobham.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. Several jobs near Chobham can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Preparing the site
- For older buildings, check the asbestos register before work
- Have the specification and drawings to hand
- Agree which areas must stay open

Why it’s worth doing now in Chobham
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Small buildings around Chobham suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Keep general-purpose fillers away from compartment walls
- Ask which product is in place before decorating
- Include service cupboards in routine inspections
- Get seals inspected before ceilings and boxing close
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.
Chobham: questions and answers
Is Chobham too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Chobham Business Centre, by Chobham?
Yes. Estates, retail parks and business parks around Chobham, Chobham Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
Do you certify or sign off fire stopping?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the products and details used.
Will you write the fire-stopping specification?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Common problems we fix in Chobham
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Any of the following is a good reason to get the joints checked over:
- Fire-stopping items raised at inspection or handover
- Openings found when ceilings come down for a refit
- Head-of-wall gaps with no fire seal
- Old intumescent sealant that has split away
Offices at parks like Chobham Business Centre (to the east of Chobham) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Before you book anyone
- Will failed sealant be removed rather than covered?
- Proof of insurance
- What the guarantee covers, and for how long
- The named product and why it was chosen
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Openings that need collars, wraps, batts or boards rather than sealant
- Writing the fire-stopping specification
- Fire risk assessments, a job for a competent assessor
