Fire stopping in Chalvey, done properly
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal, not a rule of thumb. If you have expanding foam used as fire stopping and hidden openings found during inspections, we can put it right, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers alike. Looking for mastic applicators who cover Chalvey? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In places the size of Chalvey, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
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.

What happens if it’s left?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. For buildings in places like Chalvey, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Approving the work on behalf of building control
- Plastic pipes whose detail calls for a collar or wrap
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Record which product was used where
- Don’t let anyone top up a fire seal with the wrong product
- Agree the fire-stopping specification before services go in
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, 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.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Several jobs near Chalvey can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
Getting the site ready
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints

Where services cross fire walls in Chalvey
There are three care or nursing homes within about 2 miles of Chalvey. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Theatres, wards and plant rooms at sites like Upton Hospital (to the east of Chalvey) all have compartment walls crossed by services. Tenant changes at parks like Slough Business Park (0.6 miles north of Chalvey) bring new data and services, and openings through fire-resisting walls need the specified seal. In a hotel such as Copthorne Hotel Slough - Windsor, less than half a mile to the north-west of Chalvey, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

What happens to BS 476 references for fire stopping in Chalvey?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.

Quoting for work in Chalvey
Quotes vary with the job. Expect it to depend on:
- The site’s rules and procedures
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
