Fire stopping across Moor Street

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

Common problems we fix in Moor Street

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

Site and facilities staff are often the first to spot these:

  • Open linear gaps along the top of fire-resisting walls
  • Damaged fire seals in risers and voids
  • Penetration schedules that need working through
  • Openings left by services added after handover

In a building such as Church of St Margaret, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Can the work be phased to keep areas open?
  • Whether their applicators hold CSCS cards
  • How long is the guarantee, and what does it include?

Our contractor checklist

Fire stopping in Moor Street

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Site teams most often ask us about damaged fire seals in risers and voids and openings left by services added after handover, on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: on jobs in Moor Street, preparation and product choice get the time they need.

A job near Moor Street is typically planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Settle who seals which penetrations at the start of a project
  • Look above ceilings when tiles are lifted for other jobs
  • Get seals inspected before ceilings and boxing close

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Moor Street may need directions, gate codes or a contact on site. 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. 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.

Before we start on site

  • Let building users know which areas are affected
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

FAQs: Moor Street

Is a hospital such as Medway Maritime Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Could you schedule work at a campus like University of Greenwich - Medway for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you hold third-party fire-stopping installer certification?

No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

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.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you certify or sign off fire stopping?

No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used and agree any further records when we quote.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed
  • 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. Mention the access as part of your enquiry.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • How the joints are reached, and at what height
  • The postcode of the building
  • Your programme or deadline
  • Photos of the joints, close up and from further back

For a fixed quote, ring 01277 525 020 or email us. You can also send details through our quote form.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Where services cross fire walls in Moor Street

Moor Street is about 33 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.

In a hotel such as The Green Lion Hotel, which lies west of Moor Street, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On estates like Newington Industrial Estate, which lies south-east of Moor Street, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
