About our fire stopping in West End

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. We close the openings listed on your schedule, using the specified sealant and detail. We work on cable penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and what we’re called in for most is penetration schedules that need working through and fire sealant pulled out of the opening. For commercial sealant work in West End, you deal with one contact from quote to sign-off, whether it’s one building or several.

Barn and farm-building conversions near places like West End often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Different surfaces, different methods

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance.

What sets the cost

Each job is priced on its own details. The main factors are:

  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Any access equipment needed
  • Quantities, in metres or numbers

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

However big the job, the same details help:

  • Access details, including height
  • Clear photographs of the problem areas
  • Your programme or deadline
  • Asbestos survey details if the building is older

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Work for main contractors and building owners

When you manage a building on behalf of an owner, 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.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in West End can sit alongside others in a wider programme.

West End: questions and answers

Will you plan work around the academic year at somewhere like University of Kent?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you take on a job at a hospital such as Whitstable and Tankerton Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What will the job cost?

Each job is quoted on its own details. To get one, call 01277 525 020 or email drawings and photos.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Do you work in Scotland as well as England?

Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.

Do you design or specify fire stopping?

No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.

Do you hold third-party fire-stopping installer certification?

No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so check your contract first. Where it isn’t required, we install the specified sealant to the maker’s details.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Have penetrations checked while they can still be seen
  • File the specified details where the next contractor can find them
  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near West End need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We ask for the product and detail your designer has specified.
  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. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Point out parking and an unloading spot
  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs

Advice

Service penetrations in West End buildings

Central London is about 52 miles from West End. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. There are four care or nursing homes within about 2 miles of West End. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.

Tenant changes at parks like St. Augustine's Business Park (1.1 miles north-west of West End) bring new data and services, and openings through fire-resisting walls need the specified seal. For a unit at a centre such as Buddy's Retail Park (3 miles south of West End), penetration seals are worth checking after each shop fit. Residences at universities like University of Kent (to the south of West End) have compartment walls that must be resealed whenever services change.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Approving the work on behalf of building control
  • Writing the fire-stopping specification
  • Fire doors, dampers or other fire safety equipment

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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