About our fire stopping in Weston

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you are dealing with non-fire-rated filler around services and fire stopping installed outside its tested range, we can help, whatever the surface. Whoever orders the work in Weston, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Weston is normally planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

A 12-month guarantee applies to all our work in West Berkshire. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we’ll come back to it.

Building owners, agents and FMs in Weston

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. For work around Weston, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  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.

Getting the site ready

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Service penetrations in Weston buildings

At about 57 miles from central London, Weston is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. 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.

Around Weston, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product. Older community buildings such as St Thomas' Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Weston is about 6 miles north-west of Newbury, in West Berkshire. Our applicators travel to Weston for work on service penetrations, handled exactly as we handle every other area. Weston is one of 140 places we cover in West Berkshire for service penetrations. We also cover Reading, around 19 miles from Weston.

Nearby places we also cover include East Shefford (1 mile north-west), Great Shefford (1 mile north-west), Wickham (1 mile south), Easton (2 miles south-east) and Shefford Woodlands (2 miles west). A short drive away, we cover Newbury (6 miles south-east), Thatcham (8 miles south-east), Speenhamland (6 miles south-east), Hungerford (5 miles south-west), Lambourn (5 miles north-west) and Shaw (6 miles south-east).

Your questions answered

What happens to BS 476 references for fire stopping in Weston?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Weston too small for you to travel to?

No. Places such as Weston are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you work while the building is occupied?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

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.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Construction that lacks the fire resistance the seal relies on
  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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

Why deal with it now?

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. Halls, stores and units around places like Weston may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Why us?

  • Health and safety: CHAS accredited
  • Sealing commercial buildings since 2005
  • Work to your specification and the manufacturer’s guidance
  • Joints cleaned back to sound surfaces

See our cost guide or our accreditations.

How the quote is worked out

These are the things that shape the price:

  • Access and working height
  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Backing rod, priming and other preparation

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • Any dates the work must fit around
  • The product your specification calls for
  • Where the site is, with the postcode
  • What the building is and how it’s used

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

Maintenance after handover

After handover, these steps help:

  • Arrange inspection before areas are covered up
  • Report damaged or disturbed seals as soon as they’re spotted
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Check with the data sheet before painting over fire sealant

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
