Fire stopping for businesses in Hascombe

Fire stopping in Hascombe, done properly

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, ring 01277 525 020 or email drawings and photos with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. We work on pipe penetrations, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are old intumescent sealant that has split away and fire stopping installed outside its tested range. A specialist sealant contractor works differently from a general builder: on jobs in Hascombe, preparation and product choice get the time they need.

A job near Hascombe is normally planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

What the job involves on each surface

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.

What happens if it’s left?

Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. Around Hascombe, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • CHAS accredited contractor
  • Work to your specification and the manufacturer’s guidance
  • Constructionline member for supplier checks
  • Public liability insurance in place

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Record which product was used where
  • Flag new cables with no seal around them
  • Ask which product is in place before decorating
  • Settle who seals which penetrations at the start of a project

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.

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.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Hascombe are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot
  • Share your working hours and any access restrictions

Related advice

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Questions about Hascombe

Can you work around term dates at a campus such as Godalming College?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you take on work at healthcare sites like Milford Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is fire stopping in Scotland covered by different guidance?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.

What does an EI 60 rating 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 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Fire doors, dampers or other fire safety equipment
  • Deciding what a wall or floor needs, which belongs to the designer
  • Construction that lacks the fire resistance the seal relies on

If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Service penetrations in Hascombe buildings

Hascombe lies roughly 32 miles out 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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

On a site such as Godalming Business Centre, 2.9 miles north-west of Hascombe, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Older community buildings such as Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hospital estates such as Milford Hospital (2.6 miles north-west of Hascombe) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
