How we handle fire rated sealant in Letcombe Bassett

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. Typical jobs include unsealed gaps where pipes and cables go through a wall and fire stopping disturbed by later work, across pipe & cable gaps, linear gaps and service penetrations.

Somewhere as small as Letcombe Bassett, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Questions from Letcombe Bassett

Is Letcombe Bassett within the area you cover?

Yes. Letcombe Bassett is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

What guarantee comes with fire rated sealant in Letcombe Bassett?

Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Can you give us a record of the work?

Yes. We record the locations we have sealed and the products used.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Can ordinary silicone be used in a fire-stopping gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that does not depend on other work. Older cottages and farmhouses around Letcombe Bassett can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Ask every contractor to reseal any fire stopping they disturb
  • Include fire stopping when you schedule refits
  • Look in service cupboards and ceiling voids from time to time
  • Ask which product was used before you paint

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.

When it isn’t the sealant

New sealant cannot fix everything, and we’d rather say so up front. It will not solve:

  • A wall that isn’t a fire-resisting element to begin with
  • Issuing a fire rating or certificate for a building
  • Assessing a building’s fire safety

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Joints and surfaces we work on

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

Common problems we fix in Letcombe Bassett

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.

Look out for any of the following:

  • Linear gaps at the head of walls
  • Cracked or shrunken fire-rated sealant
  • Ordinary sealant used where a fire-rated product was needed
  • Door frames with gaps between frame and wall

For buildings such as Church of St Michael, older buildings that have had new heating or wiring often have service gaps worth checking.

What your quote should include

  • Whether they’re fully insured
  • How long to leave it before use
  • Is the old sealant removed completely?
  • How much experience the applicator has

How the job changes by surface

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
