Fire rated sealant for homes and businesses in North Heath

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on flats & HMOs, pipe & cable gaps and door frames, and people most often call us about damaged fire sealant left by other trades and joints picked up in a fire-stopping survey.

For a small place like North Heath, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

All of our work is guaranteed for twelve months.

Landlord and commercial work in North Heath

Landlords and letting agents in North Heath can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

When to call us in North Heath

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.

The most common problems we see are:

  • Standard silicone or caulk in a fire-stopping gap
  • New service routes left unsealed after building work
  • Old fire sealant that has split or come away
  • Gaps flagged on a fire risk assessment

Around North Heath, as everywhere, fire rated sealant is only as good as the preparation behind it.

10 questions to ask before you book

What sealant work cannot fix

Some problems need a builder, plumber or other trade rather than us:

  • Assessing a building’s fire safety
  • Problems with the door itself rather than the gap around the frame
  • Walls or floors that weren’t built to resist fire

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

What we seal

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

The process

We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. Somewhere as small as North Heath, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Let us know if you’ve seen damp or leaks
  • Tell us about any previous sealing or DIY attempts

Advice

Fire rated sealant in North Heath: local notes

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 work to the specification you’re given, installing the product to its tested details.

Rented homes near Pulborough station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

North Heath is about 9 miles south-west of Horsham, in West Sussex.

What happens if it’s left?

Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around North Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

DIY versus a professional finish

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Questions from North Heath

Is North Heath within the area you cover?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you cover North Heath for fire rated sealant?

Yes. We work across London and the South East, and North Heath is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

Is the work guaranteed?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Can I use normal mastic around a pipe through a fire wall?

No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.
