Need fire stopping in Bilsham?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Bilsham, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First we go through the drawings, schedule or specification for the seals.
  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. We fit the backing the detail asks for, to the stated depth.
  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

  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements
  • Tell us which areas need to stay in use

Ask for a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

How we handle fire stopping in Bilsham

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. Site teams most often ask us about old intumescent sealant that has split away and builders’ foam or ordinary silicone in compartment walls, across linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations. Most enquiries from Bilsham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Barn and farm-building conversions near places like Bilsham often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Our workmanship is guaranteed for 12 months, in Bilsham as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Bilsham

What shapes the price:

  • Travel to remote or island sites
  • Access and working height
  • Site requirements such as inductions and permits
  • The size and state of each joint

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

What to include in your enquiry

A good diagnosis starts with the right details. Let us know:

  • Access details, including height
  • The type of building and who uses it
  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email drawings and photos to discuss it first.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Walls or floors that aren’t fire-resisting to begin with
  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Service penetrations in Bilsham buildings

A number of hotels sit less than 2 miles from Bilsham. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Central London is about 53 miles from Bilsham. 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.

On estates like Ford Airfield Industrial Estate, 1.1 miles to the north-east of Bilsham, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Tenant changes at centres like Arun Retail Park (to the west of Bilsham) often mean new services through walls between units.

Questions we’re asked in Bilsham

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

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.

Is Ford Airfield Industrial Estate, near Bilsham, within your area?

Yes. We cover Bilsham and the area around it, including industrial estates, business parks and retail parks such as Ford Airfield Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Do you work in Bilsham?

Yes. Sites across Bilsham are covered.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Signs you need fire stopping in Bilsham

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

Clients normally get in touch after noticing something like this:

  • Service penetrations left open after M&E works
  • Fire seals cut back for extra cables and never reinstated
  • Head-of-wall gaps with no fire seal
  • Fire-stopping items raised at inspection or handover

For a hotel such as Ancton House Hotel, which lies south-east of Bilsham, penetration seals are worth checking after any refit or services upgrade.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether their applicators hold CSCS cards

Our contractor checklist

Doing it in-house

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Looking after the joints

A few simple habits keep the new joints working:

  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Report damaged or disturbed seals as soon as they’re spotted
  • File the specified details where the next contractor can find them

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
