Fire rated sealant near Platt's Heath

Fire rated sealant for homes and businesses in Platt's Heath

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on plasterboard & masonry, flats & HMOs and pipe & cable gaps, and the jobs we see most are unsealed gaps where pipes and cables go through a wall and door frames with gaps between frame and wall.

For holiday lets, converted business premises or a community building near Platt's Heath, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

How to look after the new joints

After the cure time, these simple habits help:

  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Store the list of sealed gaps with your building paperwork
  • Plan fire stopping into any work that goes through walls or floors
  • Get damaged fire seals looked at promptly

Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Do you need fire rated sealant in Platt's Heath?

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Look out for these signs:

  • Unsealed gaps around fire door frames
  • Ordinary sealant used where a fire-rated product was needed
  • Fire seals that have cracked with movement
  • Gaps flagged on a fire risk assessment

For site and facilities teams at buildings such as Platts Heath Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Choosing a sealant specialist

Commercial buildings in Platt's Heath

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

For buildings such as Church of St Nicholas, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Lenham station, any gap left by new services in shared walls should be closed with a fire-rated product.

Leave it or put it right?

Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Around Platt's Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What you get with us

  • Neat joints and a tidy finish

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email with a short description of the job.

Can you fill the gap behind a fire door frame?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Yes. Full insurance covers our work.

Do you provide details of the products used?

Yes. We note each location and the product that went in.

The process

When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work starts. The work usually takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Platt's Heath, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is 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.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Mention any sign-in or site rules at work premises
  • Let us know about parking restrictions

Advice

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, 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.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What affects the cost of fire rated sealant

You will get a clear quote before we start. It takes into account:

  • Working hours on commercial sites
  • Whether there’s mould to deal with
  • The product the joint needs
  • How easy the joints are to reach

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the property is
  • If it’s domestic, commercial or a hotel

We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.
