Fire rated sealant for South Hayling homes and businesses

How the job changes by surface

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing.

Fire rated sealant for homes and businesses in South Hayling

Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. We work on door frames, linear gaps and service penetrations, and the jobs we see most are gaps left after a refit or conversion and joints picked up in a fire-stopping survey.

If you run a pub, café, guest house or shop in or near South Hayling, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.

Whatever the size of the job, it’s backed by our 12-month guarantee.

What affects the cost of fire rated sealant

Every job gets its own quote. This is what makes a difference:

  • The number and length of the joints
  • When we can work, for business premises
  • Any mould that needs treating
  • The product the joint needs

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Access, such as stairs, a lift or height
  • If it’s domestic, commercial or a hotel
  • Photos by email, if that is easy
  • If someone has resealed it before

If you’re in South Hayling and need fire rated sealant, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works.

We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Do you work in hotels near South Hayling?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

Where are you based?

Our base is Crawley. We work across South East England, London and Scotland.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used.

How much does fire rated sealant cost in South Hayling?

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

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. A visit to South Hayling is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  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

  • Mention if the joints have been sealed before
  • Let us know about parking restrictions
  • Tell us about access, such as stairs, a lift or high-level joints

Related advice

Why deal with it now?

A quick fill with any sealant to hand is not 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. Around South Hayling, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Signs you need fire rated sealant in South Hayling

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Any of these means the joints need attention:

  • Gaps where walls meet ceilings or slabs
  • Cracked or shrunken fire-rated sealant
  • Holes left by a change of layout
  • Door frames with gaps between frame and wall

For buildings such as St Mary's Church, gaps around pipes and cables are worth checking after any building work there.

Questions to ask before you book

  • What the quote includes, VAT included or not
  • What product goes in the joint
