Fire rated sealant near Clayton

Fire rated sealant in Clayton

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. If you have new service routes left unsealed after building work and unsealed gaps where pipes and cables go through a wall, we can help.

Somewhere as small as Clayton, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

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

Should I try it myself first?

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.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Questions from Clayton

Can you help a landlord with a rental near Hassocks station?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Can you do fire rated sealant in Clayton?

Yes. We work across London and the South East, and Clayton is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can you match the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Is it OK to seal over old sealant?

No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Do you do fire sealant around door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door, its seals and closer are for a door specialist.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Why it’s worth doing now in Clayton

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 Clayton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Do you need fire rated sealant in Clayton?

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

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

  • Ordinary sealant used where a fire-rated product was needed
  • Cracked or shrunken fire-rated sealant
  • Joints picked up in a fire-stopping survey
  • Unsealed gaps around fire door frames

Managing a site like The Windmills Junior School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Before booking anyone

  • The length of the guarantee
  • Whether you can choose the colour
  • What insurance they hold
  • How long to leave it before use

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • File the fire-stopping record where your assessor can find it
  • Do not paint over fire sealant until it has cured
  • Plan fire stopping into any work that goes through walls or floors
  • Do not fill fire-stopping gaps with ordinary foam or silicone

Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Quotes for fire rated sealant in Clayton

For a quick quote, just ask. The main things that affect it are:

  • When we can work, for business premises
  • Any mould that needs treating
  • Whether the work is at height
  • The old material and how stubborn it is

Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What we need to know

To help us quote quickly, let us know:

  • Roughly how big the job is
  • Whether it has been sealed before
  • A few pictures by email, if you can
  • Whether it’s a home or a business

We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or send us an email and describe the job and send pictures if you have them.

How it works

We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Clayton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Backing or fill is fitted where the product’s tested detail calls for 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.

Getting ready for the visit

  • Clear items away from the joints we are working on
  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in

Ask for a quote

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

When it is not the sealant

We won’t take on work that won’t last, so here’s what sealant cannot put right:

  • Big openings where sealant alone isn’t the tested solution
  • Problems with the door itself rather than the gap around the frame
  • A wall that isn’t a fire-resisting element to begin with

If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.

Joints and surfaces we work on

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

Commercial buildings in Clayton

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For landlords with property near Hassocks station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like St John the Baptist's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
