Fire stopping for West Stoke sites

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

Fire stopping in West Stoke

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Most enquiries involve fire-rated sealant that has cracked or shrunk back and snag lists that include open service penetrations, across linear gaps at wall heads, service gaps in risers and pipe penetrations. One point of contact handles commercial sealant work in West Stoke from the first photographs to the final walk-round, whether it’s one building or several.

Smaller places such as West Stoke still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

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

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a single visit for a short list of penetrations, or a phased programme for a whole building. For a building around West Stoke, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Point out parking and an unloading spot
  • Move anything stored against the joints
  • Send any specification or drawings in advance

Compartments and services around West Stoke

Approved Document B is the English guidance that covers fire stopping around 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. What we install is set by the specification, and it goes in to the tested detail. West Stoke is about 54 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Where a unit on an estate such as Polthooks Farm Industrial Estate. (1.7 miles south of West Stoke), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. In a building such as Church of St Andrew, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Your questions answered

Is West Stoke off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in West Stoke?

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.

How many days will you need on site?

It depends on the scope, but the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can staff carry on working while you are here?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Signs you need fire stopping in West Stoke

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.

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

  • Fire sealant pulled out of the opening
  • Fire seals cut back for extra cables and never reinstated
  • Service penetrations left open after M&E works
  • Seals that don’t match their tested detail

Workshops and IT rooms at colleges like Chichester College, 2.9 miles south-east of West Stoke, are re-serviced often, leaving penetrations to seal.

Our contractor checklist

Looking after the joints

A few simple habits keep the new joints working:

  • Get seals inspected before ceilings and boxing close
  • Don’t let anyone top up a fire seal with the wrong product
  • Brief every trade that openings they make must be sealed
  • Report damaged or disturbed seals as soon as they’re spotted

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

Why it’s worth doing now in West Stoke

Open service penetrations matter on ordinary days, not just in a fire: 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. For buildings around smaller places like West Stoke, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
