Fire stopping for Wyke sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

About our fire stopping in Wyke

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on linear gaps at wall heads, cable penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are damaged fire seals in risers and voids and openings left by services added after handover. Whoever orders the work in Wyke, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

For a smaller site near Wyke, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Wyke can form part of a wider programme across Surrey.

What we are called out for in Wyke

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

Common reasons buildings call us in:

  • Openings found when ceilings come down for a refit
  • Fire stopping installed outside its tested range
  • Seals disturbed by maintenance and left open
  • Open linear gaps along the top of fire-resisting walls

Workshops and IT rooms at colleges like Aldershot College (1.8 miles west of Wyke) are re-serviced often, leaving penetrations to seal.

Questions to ask before you book

  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance

How to choose a sealant contractor

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Wyke are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Flag any permit to work we will need
  • Send any specification or drawings in advance
  • Move anything stored against the joints

Wyke: questions and answers

Can you work on a hospital site such as Guildford Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you work around term dates at a campus such as University of Surrey - Manor Park Campus?

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.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Compartments and services around Wyke

Central London is about 31 miles from Wyke. Office refits around the commuter belt bring new cabling through fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

Industrial units on estates such as Hollybush Industrial Estate (to the north-west of Wyke) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Halls and meeting rooms at places like Church of St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal.

What the job involves on each surface

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail.

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. Around Wyke, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
