What happens on the day

Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. For a village or hamlet like Postling Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky

How we quote for fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • Working hours on commercial sites
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • How easy the joints are to reach

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Any access issues, like height or stairs
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that’s easy

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.

Why it’s worth doing now in Postling Green

Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around Postling Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

What sealant work cannot fix

Before you book, it’s worth knowing the limits:

  • Openings too large for sealant, which need batts, boards or another system
  • Doors that aren’t fire doors in the first place
  • Construction that does not provide fire resistance on its own

If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

Where we work in Postling Green

  • Door frames

  • Flats & HMOs

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What the job involves on each surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run so there are no open sections left.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.

Fire rated sealant around Postling Green

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.

For buildings such as Church of St Martin, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Aldington Primary School, fire-stopping around service openings should be restored whenever new services go in. For landlords with property near Westenhanger station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
