About our fire rated sealant in Gravel Castle

We often work from an action list drawn up by a fire risk assessor for buildings in Gravel Castle. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. If you’re dealing with unsealed gaps where pipes and cables go through a wall and ordinary sealant used where a fire-rated product was needed, we can help, whatever the surface.

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

All our work comes with our 12-month guarantee.

Why act early in Gravel Castle

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. Older cottages and farmhouses around Gravel Castle can have timber 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, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Why book with us

  • Fully insured
  • Quality sealants from Arbo and Everbuild
  • Any old sealant cut out fully, not covered over
  • Every job guaranteed for a year

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Check whether a sealant can be painted before decorating over it
  • Keep the record of products and locations with your fire safety documents
  • Include fire stopping when you schedule refits
  • Photograph sealed gaps before they’re covered up

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded.

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

What we do, step by step

The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. For a village or hamlet like Gravel Castle, the journey is planned in advance: 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 plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Tell us if parking is tricky
  • Let us know if you’ve seen damp or leaks

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

How the job changes by surface

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.

Workplaces and buildings in Gravel Castle

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details. Gravel Castle has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

If you look after a building such as Barham Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of St John the Baptist, service openings in its walls need the right fire-rated sealant, as in any building.

Do you need fire rated sealant in Gravel Castle?

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Look out for any of the following:

  • Unsealed gaps where pipes and cables go through a wall
  • Fire seals that have cracked with movement
  • Gaps left after a refit or conversion
  • Open gaps behind door architraves

Letting a property close to Snowdown station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common questions in Gravel Castle

I let a flat near Snowdown station. Can you help?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Do you cover smaller places like Gravel Castle?

Yes, Gravel Castle is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Are you insured?

Yes. We are fully insured for every job we do.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

Do you remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.

Does someone need to be in?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Can I choose the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
