Fire stopping in Swalecliffe

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the failures we are asked to look at most are old intumescent sealant that has split away and fire seals cut back for extra cables and never reinstated. Most enquiries from Swalecliffe start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Fire-rated sealing in a place like Swalecliffe is usually a single building at a time. Send the specification, drawings or photographs of the openings and we’ll quote to suit.

Every job we finish is backed by a 12-month workmanship guarantee, in Swalecliffe as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If neighbouring businesses or buildings around Swalecliffe need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Move anything stored against the joints
  • Point out parking and an unloading spot
  • Tell staff and tenants when we will be in

Related advice

Do you need fire stopping in Swalecliffe?

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 a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Most enquiries start with one or more of the following:

  • Fire-stopping items raised at inspection or handover
  • Fire-rated sealant that has cracked or shrunk back
  • Openings found when ceilings come down for a refit
  • Fire seals cut back for extra cables and never reinstated

For a unit at a centre such as Prospect Retail Park (2.5 miles south-west of Swalecliffe), penetration seals are worth checking after each shop fit.

Before you book anyone

  • Proof of insurance
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed

Questions about Swalecliffe

Do you cover business parks and estates near Swalecliffe, such as John Wilson Industrial Estate?

Yes. We cover Swalecliffe and the area around it, including industrial estates, business parks and retail parks such as John Wilson Industrial Estate. A few photos and the unit address let us price the work.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Can the building stay open while you work?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Where services cross fire walls in Swalecliffe

A 2-mile radius around Swalecliffe takes in a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

On estates like John Wilson Industrial Estate, which lies south-west of Swalecliffe, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. On a hospital site such as Whitstable and Tankerton Hospital, 0.6 miles west of Swalecliffe, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Signing off or certifying a building’s fire stopping
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Walls or floors that aren’t fire-resisting to begin with

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

Joints and surfaces we work on

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

Why act early in Swalecliffe

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
