Compartment walls and floors in Westley
Westley lies roughly 63 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. 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.
Workshops and IT rooms at colleges like Sparsholt College Hampshire, under half a mile to the north of Westley, are re-serviced often, leaving penetrations to seal. In a hotel such as Lainston House Hotel, 1 mile east of Westley, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Fire stopping in Westley
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. 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. Most enquiries involve seals that don’t match their tested detail and unsealed penetrations discovered above suspended ceilings, on pipe penetrations, cable penetrations and linear gaps at wall heads. Whoever orders the work in Westley, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions around Westley can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Fire risk assessments, a job for a competent assessor
- Openings that need collars, wraps, batts or boards rather than sealant
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think.
What we seal
- Pipe penetrations

Questions about Westley
How does the move away from BS 476 affect penetration seals in Westley?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you plan work around the academic year at somewhere like University of Winchester?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Looking after the joints
Regular inspection catches problems early. In particular:
- Flag new cables with no seal around them
- Record which product was used where
- Agree the fire-stopping specification before services go in
- Check risers and ceiling voids after each round of works
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Why it’s worth doing now in Westley
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Older rural buildings around Westley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Westley need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- 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
- For older buildings, check the asbestos register before work

Advice
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Removal of failed or old sealant
- Any access equipment needed
- Quantities, in metres or numbers
- Whether the work must be split into stages
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Where the site is, with the postcode
- Clear photos of the problem areas
- Access details, including height
- Specification clauses that apply
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
When to call us in Westley
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. Linear joint details set a width range and movement capability, and the seal has to sit within them.
What tends to prompt an enquiry:
- Head-of-wall gaps with no fire seal
- Penetration schedules that need working through
- Unsealed penetrations discovered above suspended ceilings
- Fire stopping installed outside its tested range
For an estates team at a campus like University of Winchester, which lies south-east of Westley, summer M&E works are normally followed by a round of penetration sealing.
