Fire stopping for businesses in Heyshott Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Surface by surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

About our fire stopping in Heyshott Green

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. We work on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the failures we are asked to look at most are fire sealant pulled out of the opening and snag lists that include open service penetrations. For commercial sealant work in Heyshott Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller places such as Heyshott Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What we’re called out for in Heyshott Green

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.

Look out for the following:

  • Damaged fire seals in risers and voids
  • Fire-rated sealant that has cracked or shrunk back
  • Unsealed openings around new pipes and cables
  • Expanding foam used as fire stopping

Older community buildings such as The Parish Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Before you book anyone

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Fire doors, dampers or other fire safety equipment
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Issuing fire ratings or certificates for seals

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

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

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Heyshott Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Old or wrong materials are cut out.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Confirm the product named in the specification
  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000

Your questions answered

Can you seal around new services in a hotel near Heyshott Green?

Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

How does the move away from BS 476 affect penetration seals in Heyshott Green?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

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 need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Penetration seals near Heyshott Green

At about 46 miles from central London, Heyshott Green is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Heyshott Green has several hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Large healthcare estates like Midhurst Community Hospital (2.3 miles north of Heyshott Green) change their services often, so penetration seals are worth checking after M&E work. Industrial units on estates such as Holmbush Industrial Estate (1.5 miles north-west of Heyshott Green) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

How the quote is worked out

Before we quote, we look at:

  • Removal of failed or old sealant
  • Travel to remote or island sites
  • Joint width, depth and condition
  • Whether the work must be split into stages

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.
