How we handle fire stopping in Forge Wood

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Forge Wood. If you have service penetrations left open after M&E works and fire sealant pulled out of the opening, we can help, on service gaps in risers, joints between fire-resisting walls and floors and linear gaps at wall heads alike. A single leaking joint is often how a building in Forge Wood 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.

Buildings in a smaller place such as Forge Wood that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we can’t put right

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

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Surfaces we seal

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

What happens if it’s left?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Why us?

  • Clear, fixed quotes
  • 12 months’ guarantee on every job
  • Over 20 years of commercial sealing
  • Work carried out by CSCS-carded applicators

On site: what to expect

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 anything is cut or cleaned, and the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. Work in places the size of Forge Wood is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  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. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Let building users know which areas are affected
  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or use the quote form.

Fire stopping in Forge Wood: the local picture

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. Either way, we install the specified product to its tested detail. Forge Wood is about 25 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

Workshops and IT rooms at colleges like Crawley College (1.9 miles south-west of Forge Wood) are re-serviced often, leaving penetrations to seal. For a unit at a centre such as County Oak Retail Park, 1.5 miles west of Forge Wood, penetration seals are worth checking after each shop fit. Hotels such as Sandman Signature London Gatwick Hotel, 1 mile south-west of Forge Wood, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Forge Wood is about 2 miles north-east of Crawley, in West Sussex. Forge Wood sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Forge Wood is one of 373 places we cover in West Sussex. There’s a separate page for Brighton, roughly 21 miles from Forge Wood.

We also cover Tinsley Green (1 mile north), Pound Hill (1 mile south), Shipley Bridge (1 mile north-east), Copthorne (1 mile east) and Three Bridges (1 mile south). Bigger towns within reach include Horsham (9 miles south-west), Haywards Heath (10 miles south), Burgess Hill (12 miles south), East Grinstead (6 miles east), Broadfield (4 miles south-west) and Billingshurst (15 miles south-west).

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Keep product data and details in the fire safety file
  • Leave fire sealant to cure fully before covering it
  • Put resealing into every M&E and fit-out package
  • Treat an open penetration as a priority repair

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you work in Scotland as well as England?

Will you quote for a small job?

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

Do you design or specify fire stopping?

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.
