How we quote for fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • How easy the joints are to reach
  • The product the joint needs
  • Mould in or behind the old joints
  • The size of the job

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • How we’d reach the joints
  • Photos by email, if that’s easy
  • If it’s domestic, commercial or a hotel
  • Where the property is

We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

Fire rated sealant in Gatton, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you have joints picked up in a fire-stopping survey and gaps filled with a product that isn’t fire-rated, we can put it right.

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

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Aftercare tips

So the new joints stay in good condition:

  • Plan fire stopping into any work that goes through walls or floors
  • Keep pictures of seals that will be hidden
  • Store the list of sealed gaps with your building paperwork
  • Make resealing part of every contractor’s brief

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

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

Signs you need fire rated sealant in Gatton

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

It’s worth asking for a quote if you see:

  • Gaps flagged on a fire risk assessment
  • Unsealed gaps where pipes and cables go through a wall
  • Old fire sealant that has split or come away
  • Open joints along the top of partitions

If you look after a building such as Lime Tree Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What to look for in a quote

  • What happens if the job turns out different
  • How the joint is cleaned and prepared
  • What guarantee comes with the work
  • When the joint can take water or movement

How to choose a mastic man

Leave it or put it right?

Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. Older cottages and farmhouses around Gatton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Your questions about fire rated sealant in Gatton

Do you cover Gatton for fire rated sealant?

Yes. Our work covers London and the South East, and Gatton is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.

I let a flat near Merstham station. Can you help?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first.

What fire rating will the seal have?

We do not give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.

What information do you need?

The location, the problem and the rough size of the job. Photos by email help too.

Do I have to be there?

We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

How it works

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Gatton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  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.

Before we arrive

  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in
  • Tell us about any previous sealing or DIY attempts

Fire rated sealant around Gatton

If you let a flat or house near Merstham station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as St Andrew's Church, older buildings that have had new heating or wiring often have service gaps worth checking.
