Fire stopping for Broadstairs sites

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

Work for main contractors and building owners

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

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

Fire stopping in Broadstairs, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. The enquiries we see most involve fire seals cut back for extra cables and never reinstated and hidden openings found during inspections, on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. One point of contact handles commercial sealant work in Broadstairs from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Older buildings in towns like Broadstairs have often been rewired and replumbed several times, and each change can leave unsealed holes in walls and floors. Intumescent or fire-rated sealant is used wherever the specification asks for it, built up exactly as tested.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Most work in Broadstairs is one building at a time: a school, a unit, an office or a block. Your photographs, drawings or a site visit come first, followed by a fixed 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. Foam, ordinary sealant and debris come out first.
  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 any areas we must not close
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why act early in Broadstairs

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. In Broadstairs, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

What you get with us

  • CSCS-carded applicators
  • 12 months’ guarantee on every job
  • Fully insured
  • Clear, fixed quotes

Take a look at our cost guide and our accreditations and insurance.

After the work

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

  • Foam or ordinary sealant is never a fire-seal repair
  • Brief every trade that openings they make must be sealed
  • Agree the fire-stopping specification before services go in
  • Arrange inspection before areas are covered up

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

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Quoting for work in Broadstairs

Each job is priced on its own details. The main factors are:

  • The product specified
  • Quantities, in metres or numbers
  • Distance, for remote addresses
  • Any access equipment needed

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • When you need the work done

For a fixed quote, give us a call on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.

Where services cross fire walls in Broadstairs

Broadstairs is about 66 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. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

On a hospital site such as Queen Elizabeth The Queen Mother Hospital, 2 miles north-west of Broadstairs, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. In a hotel such as Belvidere Hotel, 0.5 miles south-east of Broadstairs, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

What we are called out for in Broadstairs

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

These are often picked up first by site or facilities staff:

  • Fire-rated sealant that has cracked or shrunk back
  • Fire seals cut back for extra cables and never reinstated
  • Openings left by services added after handover
  • Improvised or mixed-product fire seals

On estates like Northdown Industrial Estate, 0.6 miles north-west of Broadstairs, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Questions to ask before you book

Common questions from Broadstairs clients

How does the move away from BS 476 affect penetration seals in Broadstairs?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Do you seal service penetrations in hotels around Broadstairs?

Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.
