Fire rated sealant for homes and businesses in Highstreet

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Typical jobs include holes left by a change of layout and old fire sealant that has split or come away, across flats & HMOs, service penetrations and plasterboard & masonry.

In a village or hamlet like Highstreet, 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.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What affects the cost of fire rated sealant

The price is agreed before any work begins. It’s based on:

  • Access and height
  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises

The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

What we need to know

To make quoting easier, please include:

  • The address or postcode of the job
  • Whether it has been sealed before
  • A few pictures by email, if you can
  • How we’d reach the joints

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Flag any open gap you spot round a pipe or cable
  • Check risers, ceiling voids and cupboards during building checks
  • Never patch a fire seal with standard sealant
  • Ask every contractor to reseal any fire stopping they disturb

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

What fire rated sealant looks like in Highstreet

If you run a hotel, guest house or holiday let in a coastal place like Highstreet, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

If you let a flat or house near Whitstable station, any gap left by new services in shared walls should be closed with a fire-rated product. Around Highstreet, as everywhere, fire rated sealant is only as good as the preparation behind it.

Highstreet is about 3 miles south-west of Whitstable, in Kent. Across the ME13 area, we can carry out fire rated sealant at your property. Our area takes in 922 places across Kent, from the larger towns to small villages. We also work in Chelmsford, about 36 miles from Highstreet.

For landlords and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

We also work for property managers and facilities teams. We can quote a run of properties together.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. Somewhere like Highstreet needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

How to prepare

  • Keep children and pets away from the work area
  • Move anything stored near the joints
  • For business premises, tell us about site rules or sign-in

FAQs for Highstreet

Will you come out to Highstreet?

Yes, Highstreet is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you do fire rated sealant in Highstreet?

Yes, Highstreet is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Do you carry out fire risk assessments?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

Can you fill the gap behind a fire door frame?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door leaf and its hardware need a door specialist.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

What should I tell you?

A short description and the location, with photos by email if possible. If we need more, we will ask.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.

Will the old sealant be removed?

Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

Honest limits

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Openings too large for sealant, which need batts, boards or another system
  • Assessing a building’s fire safety
  • Issuing a fire rating or certificate for a building

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

What we seal

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

Different surfaces, different methods

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment room by room.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
