Fire rated sealant in West Dean

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have unsealed gaps around fire door frames and holes left by a change of layout, we can help, whatever the surface.

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

A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Leave it or put it right?

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. Around West Dean, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email.

Commercial buildings in West Dean

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

If you let a flat or house near Fishbourne station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as The Parish Church of St Andrew, gaps around pipes and cables are worth checking after any building work there. If you look after a building such as West Dean CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

Aftercare tips

After the cure time, these simple habits help:

  • Get damaged fire seals looked at promptly
  • Ask every contractor to reseal any fire stopping they disturb
  • Include fire stopping when you schedule refits
  • Keep the record of products and locations with your fire safety documents

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

Your questions about fire rated sealant in West Dean

Will you come out to West Dean?

Yes, West Dean is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you cover West Dean for fire rated sealant?

Yes. Our work covers London and the South East, and West Dean is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

What do you need from me for a quote?

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

How do I get a quote for fire rated sealant in West Dean?

Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email with a short description of the job.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Can you tell me which gaps need fire stopping?

No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.

Can ordinary silicone be used in a fire-stopping gap?

No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.

How we quote for fire rated sealant

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

  • Whether there’s mould to deal with
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints
  • The number of rooms or windows

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

When you contact us, it’s useful to know:

  • The address or postcode of the job
  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • The problem you’ve noticed

Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job.

What the job involves on each surface

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for the gap we are sealing.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

How it works

Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as West Dean, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Let us know about stairs, lifts or work at height
  • Let us know about earlier repairs to the joints

Related advice

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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.
