How we handle fire stopping in Westgate-on-Sea

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. Site teams most often ask us about unsealed openings around new pipes and cables and head-of-wall gaps with no fire seal, across service gaps in risers, linear gaps at wall heads and joints between fire-resisting walls and floors. A specialist sealant contractor works differently from a general builder: in Westgate-on-Sea, that means joint design, primers and backing rod as standard.

Buildings in a smaller place such as Westgate-on-Sea 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.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Why it’s worth doing now in Westgate-on-Sea

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

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Why appoint us

  • One number for every site we cover
  • Old sealant cut out, never sealed over
  • Work to your specification and the manufacturer’s guidance
  • Fixed quotes based on photographs, drawings or a visit

Should maintenance staff do it?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork normally needs a different solution set by the designer.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.

What affects the price in Westgate-on-Sea

To price the job, we consider:

  • Induction, permit and paperwork requirements
  • Access and working height
  • How much there is to seal
  • Working within restricted access windows

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

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

  • Any specification or named product
  • The postcode of the building
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work

To get a fixed quote, ring 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

Common questions from Westgate-on-Sea clients

Can you work at a site such as All Saints Industrial Estate, by Westgate-on-Sea?

Yes. We cover Westgate-on-Sea and the area around it, including industrial estates, business parks and retail parks such as All Saints Industrial Estate. Photos and a short description are enough for a first look.

Will you plan work around the academic year at somewhere like TOPS Vocational College?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Which standards are fire seals tested to?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Is the BS 476 change in 2029 relevant to fire stopping?

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications. Scotland follows its own Technical Handbook.

Will you write the fire-stopping specification?

No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.

Do you need fire stopping in Westgate-on-Sea?

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

Look out for the following:

  • Old intumescent sealant that has split away
  • Snag lists that include open service penetrations
  • Seals that don’t match their tested detail
  • Service penetrations left open after M&E works

For a site team at a college like TOPS Vocational College, which lies east of Westgate-on-Sea, fire-rated sealing is best scheduled after the summer works.

What to look for in a quote

  • Proof of insurance
  • Will RAMS and insurance details be available?
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Several jobs near Westgate-on-Sea can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Confirm the product named in the specification
  • Agree which areas must stay open
  • Move anything stored against the joints

Advice

Fire-rated sealing for Westgate-on-Sea buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. A 2-mile radius around Westgate-on-Sea takes in a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

Hotels like Waterside Private Hotel, less than half a mile north-west of Westgate-on-Sea, are refurbished in phases, and each phase can open up compartment walls. Older community buildings such as Church of St Saviour that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
