Fire stopping for Willey Green sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Willey Green 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. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Send any specification or drawings in advance
  • Let building users know which areas are affected
  • Agree which areas must stay open

How we handle fire stopping in Willey Green

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with non-fire-rated filler around services and old intumescent sealant that has split away, we can help, on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows alike. A single leaking joint is often how a building in Willey Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A job near Willey Green is normally planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Willey Green: questions and answers

Do you take on work at healthcare sites like Royal Surrey County Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Is Willey Green too far out for you?

Not at all. Willey Green is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

What do BS EN 1366-3 and BS EN 13501-2 mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.

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.

Will you write the fire-stopping specification?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

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.

Why act early in Willey Green

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Older rural buildings around Willey Green 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.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Gaps in walls that were never built as compartment walls
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Plastic pipes whose detail calls for a collar or wrap

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly before you book.

What we seal

  • Pipe penetrations
  • Cable penetrations
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors

Do you need fire stopping in Willey Green?

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access typically bring them to light.

Clients usually get in touch after noticing one or more of the following:

  • Unsealed openings around new pipes and cables
  • Expanding foam used as fire stopping
  • Unsealed joints where partitions meet the slab
  • Old intumescent sealant that has split away

Older community buildings such as Church of St Mark that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Comparing quotes

  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Maintenance after handover

Cleaning and maintenance staff play a part too. Share these points with them:

  • Don’t let anyone top up a fire seal with the wrong product
  • Put resealing into every M&E and fit-out package
  • Treat an open penetration as a priority repair
  • Agree the fire-stopping specification before services go in

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.

How the job changes by surface

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Service penetrations in Willey Green buildings

Willey Green lies roughly 29 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. 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. We install whatever has been specified, to the product’s tested detail.

At a college such as Merrist Wood College (1.9 miles north-east of Willey Green), checking penetration seals after summer M&E works is good practice. Large healthcare estates like Royal Surrey County Hospital (2.3 miles south-east of Willey Green) change their services often, so penetration seals are worth checking after M&E work.
