About our fire stopping in Molash

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations, and what we’re called in for most is head-of-wall gaps with no fire seal and seals disturbed by maintenance and left open. Most enquiries from Molash start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Rural conversions around Molash can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

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

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Construction that lacks the fire resistance the seal relies on
  • Reviewing a building’s overall fire safety

If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

Where we work in Molash

Your questions answered

Can you produce the fire-stopping design for a job in Molash?

No. The designer or fire engineer sets the detail and building control accepts it. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you work in Molash?

Yes. Molash is in our area and the rest of Kent. To discuss a job, give us a call on 01277 525 020 or use the quote form.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Different surfaces, different methods

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

At about 47 miles from central London, Molash is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail.

For buildings in and around Molash, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail. In a building such as Church of St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Rural sites near Molash may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  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

  • Flag any permit to work we will need
  • Let building users know which areas are affected
  • Move anything stored against the joints

Leave it or put it right?

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, rather than turning into a full building survey and reseal. Around Molash, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
