Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Shortfield Common. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Fire stopping in Shortfield Common

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on service gaps in risers, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are openings left by services added after handover and hidden openings found during inspections. Facilities teams, main contractors and managing agents in Shortfield Common tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Shortfield Common 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Include service cupboards in routine inspections
  • Have penetrations checked while they can still be seen
  • Brief every trade that openings they make must be sealed
  • Keep general-purpose fillers away from compartment walls

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Issuing fire ratings or certificates for seals
  • Writing the fire-stopping specification
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, ring 01277 525 020 or email the details over and we will say what we think before you book.

What we seal

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

Shortfield Common: questions and answers

Do you cover business parks and estates near Shortfield Common, such as Grovebell Industrial Estate?

Yes, sites like Grovebell Industrial Estate are within our area, along with the rest of Shortfield Common. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.

Could you schedule work at a campus like University for the Creative Arts for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do you guarantee your work?

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

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.

How much does the work cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Penetration seals near Shortfield Common

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Shortfield Common is about 38 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

For a building such as Church of St Mary the Virgin, new heating or data runs are the usual reason penetrations need sealing. Schools such as Edgeborough School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Residences at universities like University for the Creative Arts (2.8 miles north of Shortfield Common) have compartment walls that must be resealed whenever services change.

Diagnose, treat, sign off

In a busy building, 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 the next one starts. For a building around Shortfield Common, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We ask for the product and detail your designer has specified.
  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. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Confirm the product named in the specification

Advice

Leave it or put it right?

Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Around Shortfield Common, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.
