Trusted fire rated sealant in Halfway

How we handle fire rated sealant in Halfway

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. We’re often asked to deal with damaged fire sealant left by other trades and joints picked up in a fire-stopping survey, on pipe & cable gaps, plasterboard & masonry and linear gaps.

For a small place like Halfway, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

All our work comes with our 12-month guarantee.

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

How the job changes by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail.

Why act early in Halfway

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around Halfway can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

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

How it works

We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Halfway, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Mention any leaks or damp you’ve noticed
  • Let us know about stairs, lifts or work at height

Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Signs it’s time to call us include:

  • Joints picked up in a fire-stopping survey
  • Open gaps behind door architraves
  • Fire stopping disturbed by later work
  • Open holes round services passing through fire walls

For landlords with property near Kintbury station, any gap left by new services in shared walls should be closed with a fire-rated product.

Our hiring checklist

Halfway questions

Will you come out to Halfway?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Kintbury station?

Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Do you offer different sealant colours?

Most of the time, yes. We’ll tell you which colours the right product comes in.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Is it OK to seal over old sealant?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

What’s the difference between intumescent and fire-rated sealant?

An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

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.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
