Fire stopping for commercial buildings in Chilworth
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 sites in Chilworth. We work on service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations, and what we’re called in for most is fire seals cut back for extra cables and never reinstated and open linear gaps along the top of fire-resisting walls. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Chilworth is the same: the right product in a properly prepared joint.
Smaller places such as Chilworth still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
A 12-month guarantee applies to all our work in Surrey. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we will come back to it.

How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Working within restricted access windows
- Induction, permit and paperwork requirements
- Any access equipment needed
- Removal of failed or old sealant
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
Sending details for a quote
A few photos plus some basic facts will normally do. Please tell us:
- Clear photographs of the problem areas
- Any dates the work must fit around
- Any specification or named product
- The type of building and who uses it
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or use the quote form.
Penetration seals near Chilworth
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail. Chilworth lies roughly 27 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
For an estates team at a campus like University of Surrey - Stag Hill Campus, 3.1 miles to the north-west of Chilworth, summer M&E works are normally followed by a round of penetration sealing. Wherever services are added at a hospital such as Mount Alvernia Hospital, 1.9 miles north-west of Chilworth, the compartment line has to be made good with the specified product.
Chilworth is about 3 miles south-east of Guildford, in Surrey. Looking for fire stopping in Chilworth? We can help, as we do across Surrey. Our Surrey coverage takes in 379 places. Sites around Reading have their own page, roughly 25 miles from Chilworth.

How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Chilworth are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
- Have the specification and drawings to hand
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Advice
After the work
To get the most from the new sealant:
- Check risers and ceiling voids after each round of works
- Keep product data and details in the fire safety file
- Put resealing into every M&E and fit-out package
- Foam or ordinary sealant is never a fire-seal repair
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
Why it’s worth doing now in Chilworth
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. Around Chilworth, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

When to call us in Chilworth
Openings in fire-resisting walls typically appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Most enquiries start with one or more of the following:
- Builders’ foam or ordinary silicone in compartment walls
- Improvised or mixed-product fire seals
- Fire-rated sealant that has cracked or shrunk back
- Openings left by services added after handover
For a hotel such as Barnett Hill House Hotel, 1.1 miles south of Chilworth, penetration seals are worth checking after any refit or services upgrade.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
- Their plan for phasing and protecting the area
- What the guarantee covers, and for how long
Your questions answered
Will you plan work around the academic year at somewhere like University of Surrey - Stag Hill Campus?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Chilworth too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
