Fire rated sealant in West Thorney

Bigger jobs can be worked through in stages, flat by flat or floor by floor. That record is useful for your files and for whoever looks at the building next. We are often asked to deal with open joints along the top of partitions and fire stopping disturbed by later work, on plasterboard & masonry, pipe & cable gaps and linear gaps.

In a village or hamlet like West Thorney, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Our work is backed for twelve months.

What happens if it’s left?

Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again when the building is next checked. Around West Thorney, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.

How it works

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like West Thorney needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  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.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Mention any parking rules near the property
  • Plan for the work area to be out of bounds to pets and children

Related advice

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Ask which product was used before you paint
  • Look in service cupboards and ceiling voids from time to time
  • Never patch a fire seal with standard sealant
  • Keep the record of products and locations with your fire safety documents

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.

Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

How we quote for fire rated sealant

We do not publish a price list, because jobs vary so much. What we look at:

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

What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before we start.

What to tell us for a quote

To help us quote quickly, please include:

  • A few photos by email, if you can
  • Any previous sealing or DIY work
  • The rough size of the job
  • Any access issues, like height or stairs

Workplaces and buildings in West Thorney

For seaside hotels, guest houses and holiday lets around West Thorney, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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’re given, installing the product to its tested details.

Community buildings like The Parish Church of St Nicholas 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 Thorney Island Community Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

When to call us in West Thorney

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

Most people get in touch after spotting one of these:

  • Open holes round services passing through fire walls
  • Old fire sealant that has split or come away
  • Holes left by a change of layout
  • Fire stopping disturbed by later work

Rented homes near Southbourne station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

10 questions to ask before you book

West Thorney questions

Do you work for landlords with property near Southbourne station?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Will you come out to West Thorney?

Yes. West Thorney is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

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

No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used, so you have it on file.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can I add another job to the visit?

Yes. Just list everything you need.

Is there a guarantee?

Yes. All our work carries a one-year guarantee.

Can you tell me which gaps need fire stopping?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

Honest limits

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Large holes that need a different fire-stopping system
  • Certifying a building or signing off its fire safety
  • A wall that isn’t a fire-resisting element to begin with

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
