Fire stopping for Neatham sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Neatham may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • Share your working hours and any access restrictions

Ask for a quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or send details through our quote form.

About our fire stopping in Neatham

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. 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. We work on pipe penetrations, cable penetrations and linear gaps at wall heads, and what we’re called in for most is unsealed joints where partitions meet the slab and non-fire-rated filler around services. For commercial sealant work in Neatham, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a smaller site near Neatham, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

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

For managing agents and facilities managers

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Common questions from Neatham clients

Do you cover business parks and estates near Neatham, such as Kerridge Industrial Estate?

Yes, sites like Kerridge Industrial Estate are within our area, along with the rest of Neatham. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Alton Community Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

What will the job cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

What do BS EN 1366-3 and BS EN 13501-2 mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2. The rating applies to the product as tested.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Different surfaces, different methods

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.

Masonry and concrete

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

Service penetrations in Neatham buildings

Neatham is about 43 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.

Hospital estates such as Alton Community Hospital (2.6 miles south-west of Neatham) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Older community buildings such as Holy Rood Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Neatham is about 2 miles north-east of Alton, in Hampshire. Neatham sits inside our coverage and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 723 places across Hampshire fall within our area, including Neatham. For work in that direction, see our Reading page, about 20 miles away.

Looking after the joints

After handover, these steps help:

  • Brief every trade that openings they make must be sealed
  • Leave fire sealant to cure fully before covering it
  • Keep general-purpose fillers away from compartment walls
  • Get seals inspected before ceilings and boxing close

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

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:

  • Plastic pipes whose detail calls for a collar or wrap
  • Construction that lacks the fire resistance the seal relies on
  • Deciding what a wall or floor needs, which belongs to the designer

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

Surfaces we seal

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

Common problems we fix in Neatham

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Look out for the following:

  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back
  • Head-of-wall gaps with no fire seal
  • Openings found when ceilings come down for a refit

Hotels such as Alton House Hotel, 1.4 miles south-west of Neatham, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area
  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?
