Fire rated sealant near Coggins Mill

What the job involves on each surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

Fire rated sealant in Coggins Mill

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on service penetrations, flats & HMOs and plasterboard & masonry, and people most often call us about gaps filled with a product that isn’t fire-rated and gaps where walls meet ceilings or slabs.

For a small place like Coggins Mill, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Common problems we fix in Coggins Mill

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Look out for any of the following:

  • Linear gaps at the head of walls
  • Unsealed gaps around fire door frames
  • Sealant items on a fire risk assessment action list
  • Gaps left after a refit or conversion

For buildings such as Church of St. Dunstan, service openings in its walls need the right fire-rated sealant, as in any building.

What your quote should include

  • What product goes in the joint
  • What guarantee comes with the work
  • What happens if the job turns out different
  • Whether you can choose the colour

Choosing a sealant specialist

When it isn’t the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:

  • Sign-off of the building, which sits with building control or your assessor
  • Deciding what fire stopping a building needs
  • Fire doors that need new seals, closers or hardware

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

Where we work in Coggins Mill

  • Service penetrations
  • Linear gaps
  • Pipe & cable gaps
  • Flats & HMOs
  • Plasterboard & masonry
  • Door frames

Work for landlords, hotels and businesses

Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

How to look after the new joints

After the cure time, these simple habits help:

  • Include fire stopping when you schedule refits
  • Tell trades working in the building that fire seals must be put back
  • Flag any open gap you spot round a pipe or cable
  • Include hidden areas like risers in routine checks

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.

Coggins Mill questions

Is Coggins Mill in your area for fire rated sealant?

Yes. Our work covers London and the South East, and Coggins Mill is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.

I let a flat near Wadhurst station. Can you help?

Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

What fire rating will the seal have?

We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

Do you take on fire stopping in schools and offices?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

How long does fire rated sealant take?

As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer.

Where are you based?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

What does intumescent mean?

Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

Do you offer different sealant colours?

We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

Workplaces and buildings in Coggins Mill

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Wadhurst station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Mayfield Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What happens on the day

Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Coggins Mill, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Clear the area around the work
  • Let us know about stairs, lifts or work at height
  • Tell us if parking is tricky
