Fire rated sealant in Binsted

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on flats & HMOs, linear gaps and service penetrations, and people most often call us about open joints along the top of partitions and unsealed gaps around fire door frames.

In a village or hamlet like Binsted, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Common questions in Binsted

Do you work for landlords with property near Bentley (Hampshire) station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Will you come out to Binsted?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures.

Will you assess my building’s fire safety?

No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

What does intumescent mean?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Surface by surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product.

How it works

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. The work normally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Binsted needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about earlier repairs to the joints

Workplaces and buildings in Binsted

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of the Holy Cross are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Bentley (Hampshire) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Binsted Church of England Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Why it’s worth doing now in Binsted

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Around Binsted, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Why book with us

  • Fully insured
  • An ARBOMaster approved applicator
  • A 12-month guarantee on all work
  • Domestic, commercial and hotel work

See our cost guide or our reviews.

Looking after it afterwards

After the cure time, these simple habits help:

  • Get damaged fire seals looked at promptly
  • Ask every contractor to reseal any fire stopping they disturb
  • Ask which product was used before you paint
  • File the fire-stopping record where your assessor can find it

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.

How we quote for fire rated sealant

You’ll get a clear quote before work begins. It’s based on:

  • The product the joint needs
  • How many rooms, windows or areas are involved
  • When we can work, for business premises
  • The old material and how stubborn it is

We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Helping us quote

Photos help, but a description is a good start. Please mention:

  • The problem you’ve noticed
  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
