How we handle fire rated sealant in Cranbrook Common

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on door frames, service penetrations and flats & HMOs, and common reasons people get in touch are linear gaps at the head of walls and gaps around pipes and cables through fire-resisting walls.

In a village or hamlet like Cranbrook Common, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

You get a 12-month guarantee, the same in Cranbrook Common as everywhere else we work.

Why deal with it now?

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Around Cranbrook Common, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.

Quotes for fire rated sealant in Cranbrook Common

The quote reflects the job in front of us. We look at:

  • Access and height
  • How many areas need sealing
  • Which sealant suits the joint
  • When we can work, for business premises

What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • Access, such as stairs, a lift or height
  • Where the property is
  • Any previous sealing or DIY work
  • The problem you’ve noticed

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

When it isn’t the sealant

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware
  • Openings too large for sealant, which need batts, boards or another system

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Joints and surfaces we work on

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

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

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.

Different surfaces, different methods

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both, following the tested detail.

Your questions about fire rated sealant in Cranbrook Common

Do you cover smaller places like Cranbrook Common?

Yes. Cranbrook Common is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Cranbrook Common for fire rated sealant?

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

Will the old sealant be removed?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Is the work guaranteed?

Yes. Each job is guaranteed for twelve months, wherever you are.

How long will you be here?

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.

Can tenants book the work?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

What does intumescent mean?

An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

Is standard sealant good enough for a fire gap?

No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.

Fire rated sealant in Cranbrook Common: 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

For buildings such as Church of the Holy Trinity, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Staplehurst station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Cranbrook School, service openings in fire-resisting walls need checking after any refurbishment.
