Compartment walls and floors in Woodcote Green

The 2 miles around Woodcote Green include seven care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment 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.

Industrial units on estates such as Ullswater Industrial Estate (1.7 miles south-east of Woodcote Green) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Halls and meeting rooms at places like St. Patrick's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Wherever services are added at a hospital such as Purley War Memorial Hospital (to the east of Woodcote Green) the compartment line has to be made good with the specified product.

Woodcote Green is about 1 mile west of Purley, in Greater London. Across the CR8 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

How we handle fire stopping in Woodcote Green

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. Most enquiries involve unsealed openings around new pipes and cables and expanding foam used as fire stopping, on pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Woodcote Green from the first photos to the final walk-round, whether it’s one building or several.

In a London area such as Woodcote Green, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.

Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

How the job changes by surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Commercial clients in Woodcote Green

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Leave it or put it right?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Getting scaffold, permits or access booked in Woodcote Green takes effort, so it makes sense to deal with every failing joint while access is in place.

A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • Work carried out by CSCS-carded applicators
  • Products installed to the manufacturer’s instructions
  • Failed material removed, not covered up
  • Constructionline member for supplier checks

Questions we’re asked in Woodcote Green

Can work in a care setting near Woodcote Green go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Would you work within a site like Purley War Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

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, and any records you need can be confirmed with the quote.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Tell staff and tenants when we will be in

Ask for a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Issuing fire ratings or certificates for seals
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Where we work in Woodcote Green

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

What affects the price in Woodcote Green

These are the things that shape the price:

  • The size and state of each joint
  • Which sealant the job calls for
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • The type of building and who uses it
  • Any specification or named product
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
