Fire rated sealant for homes and businesses in Hawkenbury

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. We work on service penetrations, pipe & cable gaps and flats & HMOs, and the jobs we see most are joints picked up in a fire-stopping survey and new service routes left unsealed after building work.

If you have holiday lets, a converted barn used for business or a community building near Hawkenbury, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

You get a one-year guarantee, the same in Hawkenbury as everywhere else we work.

When it isn’t the sealant

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Fire doors that need new seals, closers or hardware
  • Certifying a building or signing off its fire safety
  • Walls or floors that weren’t built to resist fire

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Joints and surfaces we work on

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

Aftercare tips

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

  • Include hidden areas like risers in routine checks
  • Check whether a sealant can be painted before decorating over it
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Ask every contractor to reseal any fire stopping they disturb

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Surface by surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins to keep disruption down.

Plasterboard walls

We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.

Should I try it myself 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 does not work out, we can still put it right.

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.

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is intumescent sealant the same as fire-rated sealant?

Intumescent means it swells when heated. Intumescent sealants are one kind 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. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.

How we quote for fire rated sealant

You will get a clear quote before work begins. It takes into account:

  • The amount of work
  • How much old sealant there is and how hard it is to remove
  • The product the joint needs
  • Whether the work is at height

  • How we’d reach the joints
  • If it’s domestic, commercial or a hotel

How it works

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Hawkenbury, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can
