Compartment walls and floors in Sutton
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. What we install is set by the specification, and it goes in to the tested detail. Sutton lies roughly 46 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
On a hospital site such as Arundel and District Hospital, 5.3 miles south-east of Sutton, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Sutton is about 9 miles north-west of Littlehampton, in West Sussex. Our applicators travel to Sutton for work on service penetrations, handled exactly as we handle every other area.

About our fire stopping in Sutton
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. Most enquiries involve damaged fire seals in risers and voids and fire stopping installed outside its tested range, across small duct penetrations where the tested detail allows, cable penetrations and joints between fire-resisting walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, in Sutton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near Sutton is normally planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Quoting for work in Sutton
Before we quote, we look at:
- The size and state of each joint
- Any access equipment needed
- How much there is to seal
- Whether the work must be split into stages
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Your programme or deadline
- Approximate linear metres or a joint schedule
- The site address and postcode
- Clear photographs of the problem areas
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Sutton, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- 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
- Point out parking and an unloading spot
- Agree which areas must stay open
- Let building users know which areas are affected

Advice
Questions we’re asked in Sutton
What does the BS 476 change mean for fire-rated sealant in Sutton?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is a smaller place like Sutton outside your area?
Not at all. Sutton is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Common problems we fix in Sutton
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Any of the following is a good reason to get the joints checked over:
- Damaged fire seals in risers and voids
- Hidden openings found during inspections
- Open linear gaps along the top of fire-resisting walls
- Seals that don’t match their tested detail
For a building such as The Parish Church of the Holy Cross, new heating or data runs are the usual reason penetrations need sealing.
What your quote should include
- How the joint faces will be prepared and primed
- Health and safety accreditation such as CHAS
- Their public liability cover
- How they’ll work around occupants
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
How the job changes by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Check risers and ceiling voids after each round of works
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
- File the specified details where the next contractor can find them
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
