Common problems we fix in Gillette Corner

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

What tends to prompt an enquiry:

  • Non-fire-rated filler around services
  • Fire stopping installed outside its tested range
  • Fire sealant pulled out of the opening
  • Head-of-wall gaps with no fire seal

For a site team at a college like West Thames College (0.8 miles south-west of Gillette Corner), fire-rated sealing is best scheduled after the summer works.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?

About our fire stopping in Gillette Corner

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Gillette Corner and nearby. We work on pipe penetrations, cable penetrations and joints between fire-resisting walls and floors, and what we are called in for most is old intumescent sealant that has split away and head-of-wall gaps with no fire seal. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Gillette Corner, that means joint design, primers and backing rod as standard.

In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Aftercare for building managers

For the best life from the joints:

  • Ask which product is in place before decorating
  • Have penetrations checked while they can still be seen
  • Keep general-purpose fillers away from compartment walls
  • Report damaged or disturbed seals as soon as they’re spotted

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Gillette Corner can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

Questions about Gillette Corner

Can you take on a job at a hospital such as West Middlesex 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.

Do you work on fire-rated sealing in hotels in Gillette Corner?

Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you work in Gillette Corner?

Yes. Gillette Corner falls within our area, and you can call the office on 01277 525 020 or use the quote form to get started.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Cost factors for service penetrations

The price varies from site to site. Expect it to depend on:

  • Access and working height
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How much there is to seal

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • Whether an asbestos survey exists
  • Clear photos of the problem areas
  • The postcode of the building
  • Access details, including height

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Commercial clients in Gillette Corner

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

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.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping
  • Reviewing a building’s overall fire safety

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

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

Compartments and services around Gillette Corner

The area within 2 miles of Gillette Corner holds a good number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.

Hospital estates such as West Middlesex Hospital, 0.8 miles to the south of Gillette Corner, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For an estates team at a campus like University of West London (Brentford Campus), 0.7 miles to the north-east of Gillette Corner, summer M&E works are usually followed by a round of penetration sealing.
