About our fire stopping in Wormshill

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. Site teams most often ask us about non-fire-rated filler around services and seals that don’t match their tested detail, across cable penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. One point of contact handles commercial sealant work in Wormshill from the first photos to the final walk-round, for single jobs and planned programmes alike.

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

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Your questions answered

Is hospital work, at somewhere like KIMS hospital, something you do?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Could you schedule work at a campus like Canterbury Christ Church University 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.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is your workmanship covered by a guarantee?

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

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Signs you need fire stopping in Wormshill

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.

Any of the following is a good reason to get the joints checked over:

  • Openings left by services added after handover
  • Fire-stopping items raised at inspection or handover
  • Openings found when ceilings come down for a refit
  • Non-fire-rated filler around services

At a healthcare site like KIMS hospital, which lies west of Wormshill, new services through compartment walls are a constant, and each needs the specified seal.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Health and safety accreditation such as CHAS
  • Who will actually carry out the work
  • What site paperwork they can supply

Our contractor checklist

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Surfaces we seal

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

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Our process

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. Jobs in and around smaller places like Wormshill are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Agree which areas must stay open
  • Make sure the joints can be reached
  • Tell staff and tenants when we will be in

Fire-rated sealing for Wormshill buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 37 miles from Wormshill. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

At a university such as Canterbury Christ Church University, 1.3 miles to the south-west of Wormshill, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a building at a site such as Kent Science Park, which lies north-east of Wormshill, a check of penetration seals after each fit-out is good practice.

Wormshill is about 4 miles south-west of Sittingbourne, in Kent. Anywhere in ME9, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 931 places across Kent fall within our area, Wormshill among them. There’s a separate page for London, roughly 37 miles from Wormshill.

How the job changes by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
