Fire stopping for Hale Green sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Questions we are asked in Hale Green

Can you work on a hospital site such as Hellingly Hospital Railway?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

What does the BS 476 change mean for fire-rated sealant in Hale Green?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do your applicators hold CSCS cards?

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

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How we handle fire stopping in Hale Green

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call the office on 01277 525 020 or email drawings and photos with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about openings left by services added after handover and builders’ foam or ordinary silicone in compartment walls, on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations. Most enquiries from Hale Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around smaller places like Hale Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

A 12-month guarantee applies to all our work in East Sussex. If an installation problem shows up, phone 01277 525 020 or email the details over and we’ll arrange a return visit.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. If others near Hale Green need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. The specification and schedule come first, so we know which details apply.
  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. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Send any specification or drawings in advance
  • Flag any permit to work we will need
  • Share your working hours and any access restrictions

Advice

What the job involves on each surface

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

Fire stopping around Hale Green: what changes locally

Hale Green is about 43 miles from central London. 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. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

On a site such as Oakwood Business Park, which lies south-west of Hale Green, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Holiday works at schools like Chiddingly Primary School often leave service openings to seal before pupils return.

Hale Green is about 4 miles north-west of Hailsham, in East Sussex. Across the BN8 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our East Sussex coverage takes in 308 places, large and small. For work in that direction, see our Brighton page (16 miles or so).

Signs you need fire stopping in Hale Green

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position.

If one of these sounds familiar, it’s time for a closer look:

  • Fire seals cut back for extra cables and never reinstated
  • Open linear gaps along the top of fire-resisting walls
  • Penetration schedules that need working through
  • Fire-rated sealant that has cracked or shrunk back

Halls and meeting rooms at places like The Parish Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?
  • Who will actually carry out the work
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Commercial clients in Hale Green

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire risk assessments, a job for a competent assessor
  • Signing off or certifying a building’s fire stopping

If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
