Fire rated sealant for Cooper's Green homes and businesses

Fire rated sealant in Cooper's Green, done properly

We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on linear gaps, flats & HMOs and pipe & cable gaps, and the jobs we see most are new service routes left unsealed after building work and gaps filled with a product that isn’t fire-rated.

Somewhere as small as Cooper's Green, 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.

Big or small, you get the same 12-month guarantee.

Your questions about fire rated sealant in Cooper's Green

Do you work in hotels near Cooper's Green?

Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.

Do you work for landlords with property near Buxted station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Can you fill the gap behind a fire door frame?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Why it’s worth doing now in Cooper's Green

A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Around Cooper's Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Commercial buildings in Cooper's Green

There are hotels and other places to stay in and around Cooper's Green. Hotel work can be planned room by room, with out-of-hours working where needed. 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.

If you let a flat or house near Buxted station, any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like Five Ash Down Independent Chapel are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Bonners CofE School, gaps opened by contractors for new cabling are a common finding in schools and offices.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Store the list of sealed gaps with your building paperwork
  • Flag any open gap you spot round a pipe or cable
  • Include hidden areas like risers in routine checks
  • Do not paint over fire sealant until it has cured

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Cooper's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  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 for your records.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about parking restrictions
  • On commercial sites, let us know about site rules

What the job involves on each surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins to keep disruption down.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.

When something else is needed

New sealant can’t fix everything, and we will tell you before any work starts. It won’t solve:

  • Walls or floors that weren’t built to resist fire
  • Openings too large for sealant, which need batts, boards or another system
  • Problems with the door itself rather than the gap around the frame

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Surfaces we seal

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