Fire stopping for Borden sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How we handle fire stopping in Borden

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on service gaps in risers, linear gaps at wall heads and cable penetrations, and the failures we are asked to look at most are snag lists that include open service penetrations and builders’ foam or ordinary silicone in compartment walls. Whoever orders the work in Borden, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

A job near Borden is normally planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Signs you need fire stopping in Borden

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.

It’s worth sending us details if you spot any of the following:

  • Old intumescent sealant that has split away
  • Penetration schedules that need working through
  • Service penetrations left open after M&E works
  • Expanding foam used as fire stopping

For a building such as Church of St Peter, new heating or data runs are the usual reason penetrations need sealing.

Comparing quotes

  • Which product they’ll use, and why it suits the joint
  • Who will actually carry out the work
  • Whether old or failed sealant will be cut out, not overlaid
  • Will RAMS and insurance details be available?

Questions about Borden

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Borden?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Borden too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months on every job.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. If others near Borden need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Brief every trade that openings they make must be sealed
  • File the specified details where the next contractor can find them
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep general-purpose fillers away from compartment walls

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

Why it’s worth doing now in Borden

The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. For buildings around smaller places like Borden, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What you get with us

  • Joints cleaned back to sound surfaces
  • CHAS accredited contractor
  • Workmanship guaranteed for 12 months
  • Fully insured, including public liability cover

Fire stopping around Borden: how the place shapes the job

Borden lies roughly 46 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

What the job involves on each surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.
