Trusted fire rated sealant in Sprat's Down

What the job involves on each surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

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.

Fire rated sealant for homes and businesses in Sprat's Down

We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on service penetrations, door frames and linear gaps, and common reasons people get in touch are joints picked up in a fire-stopping survey and gaps filled with a product that isn’t fire-rated.

In a village or hamlet like Sprat's Down, 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.

You get a 12-month guarantee, the same in Sprat's Down as everywhere else we work.

What we do, step by step

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. In a small place like Sprat's Down, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know if you’ve seen damp or leaks
  • Keep pets and children clear of the area while we work

What we are called out for in Sprat's Down

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

These are the problems we’re asked about most:

  • Gaps left after a refit or conversion
  • Fire stopping disturbed by later work
  • Gaps where walls meet ceilings or slabs
  • Unsealed gaps where pipes and cables go through a wall

Community buildings like St George are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What your quote should include

  • What insurance they hold
  • Which sealant they’ll use, and why
  • How hidden problems are handled
  • Is VAT in the price?

Choosing a sealant specialist

Looking after it afterwards

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

  • Take pictures of fire stopping before ceilings or boxing go back
  • Never patch a fire seal with standard sealant
  • Don’t paint over fire sealant until it has cured
  • Check risers, ceiling voids and cupboards during building checks

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Questions from Sprat's Down

Do you work for hotels and guest houses in Sprat's Down?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

Can you help a landlord with a rental near Hamble station?

Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Is the work guaranteed?

Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.

Can you fill the gap behind a fire door frame?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself, and we will mention anything we notice about the door.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Do you certify the fire stopping?

That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.

For landlords and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Doors that aren’t fire doors in the first place
  • Assessing a building’s fire safety
  • Construction that does not provide fire resistance on its own

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Surfaces we seal

  • Service penetrations
  • Door frames
  • Linear gaps
  • Plasterboard & masonry
  • Pipe & cable gaps
  • Flats & HMOs

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. Where a wall is exposed, as many are in small places like Sprat's Down, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Why Sprat's Down customers choose us

  • Old sealant always removed completely
  • 12-month guarantee on every job
