How we quote for fire rated sealant

We quote each job individually. This is what makes a difference:

  • Which sealant suits the joint
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out
  • How many rooms, windows or areas are involved

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • The rough size of the job
  • The problem you’ve noticed
  • Where the job is, and your postcode
  • If someone has resealed it before

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved and give you a clear quote.

Fire rated sealant for homes and businesses in Gold Street

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We are often asked to deal with joints picked up in a fire-stopping survey and door frames with gaps between frame and wall, across service penetrations, plasterboard & masonry and flats & HMOs.

If you have holiday lets, a converted barn used for business or a community building near Gold Street, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Every job is covered by our one-year guarantee.

What the job involves on each surface

Linear gaps

Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both.

Flats and HMOs

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

Questions from Gold Street

I let a flat near Sole Street station. Can you help?

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 any work starts.

Will you come out to Gold Street?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you do fire sealant around door frames?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

What fire rating will the seal have?

That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.

Can you tell me which gaps need fire stopping?

No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

What we do, step by step

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. The work normally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Gold Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  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.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Clear items away from the joints we are working on
  • Mention any tricky access

What sealant work cannot fix

We will not take on work that won’t last, so these are the limits:

  • Issuing a fire rating or certificate for a building
  • Construction that doesn’t provide fire resistance on its own
  • Big openings where sealant alone isn’t the tested solution

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.

Where we work in Gold Street

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

When to call us in Gold Street

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

If you can see any of these, it’s time to have the joints looked at:

  • Linear gaps at the head of walls
  • Holes left by a change of layout
  • Unsealed gaps where pipes and cables go through a wall
  • Cracked or shrunken fire-rated sealant

Community buildings like St Mary's Room are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Workplaces and buildings in Gold Street

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.

Letting a property close to Sole Street station? Then any gap left by new services in shared walls should be closed with a fire-rated product. Managing a site like Cobham Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • File the fire-stopping record where your assessor can find it
  • Ask every contractor to reseal any fire stopping they disturb
  • Take pictures of fire stopping before ceilings or boxing go back
  • Get damaged fire seals looked at promptly

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is generally a straightforward job.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

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