Fire rated sealant near Barcombe Cross

Fire rated sealant in Barcombe Cross, done properly

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. We work on plasterboard & masonry, flats & HMOs and linear gaps, and the jobs we see most are joints picked up in a fire-stopping survey and seals cut through by electricians, plumbers or data installers.

Somewhere as small as Barcombe Cross, 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.

A 12-month guarantee comes as standard, so you are covered after we have gone.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Looking after it afterwards

Looking after new joints is easy:

  • Include fire stopping when you schedule refits
  • Tell trades working in the building that fire seals must be put back
  • Check whether a sealant can be painted before decorating over it
  • Report cracked or damaged seals as soon as you notice them

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.

The process

You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. In a small place like Barcombe Cross, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks
  • For business premises, tell us about site rules or sign-in

Why act early in Barcombe Cross

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Around Barcombe Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Why Barcombe Cross clients choose us

  • Anti-fungal silicone where joints get wet
  • Arbo and Everbuild products
  • Fully insured
  • Experience in homes, commercial sites and hotels

Fire rated sealant in Barcombe Cross: local notes

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 work to the specification you are given, installing the product to its tested details.

Community buildings like St Francis of Assisi are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Cooksbridge station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Barcombe Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.
