FAQs: Shawford
Will you plan work around the academic year at somewhere like University of Winchester?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Shawford off your patch?
No. Places such as Shawford are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How much does the work cost?
Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or email the details over.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.
Is sealant suitable for all service openings?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we flag those rather than improvise.
Fire stopping for commercial buildings in Shawford
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with damaged fire seals in risers and voids and fire-rated sealant that has cracked or shrunk back, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Shawford it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller places such as Shawford still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables, so we check before sealing.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Diagnose, treat, sign off

Penetration seals near Shawford
At about 63 miles from central London, Shawford is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Schools such as Compton All Saints Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Signs you need fire stopping in Shawford
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Look out for the following:
- Seals that don’t match their tested detail
- Open linear gaps along the top of fire-resisting walls
- Fire seals cut back for extra cables and never reinstated
- Penetration schedules that need working through
Residences at universities like University of Winchester, 2.6 miles north of Shawford, have compartment walls that must be resealed whenever services change.

- Is depth set with backing rod, or bond-breaker tape in shallow joints?
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Halls, stores and units around places like Shawford may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
