About our fire rated sealant in Gunville

We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on door frames, linear gaps and plasterboard & masonry, and common reasons people get in touch are gaps flagged on a fire risk assessment and gaps around pipes and cables through fire-resisting walls.

For a small place like Gunville, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

All our work comes with a 12-month guarantee.

How it works

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. Somewhere like Gunville 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. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  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.

Preparing for the visit

  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work

Aftercare tips

After the cure time, these simple habits help:

  • Keep the record of products and locations with your fire safety documents
  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • Allow for resealing whenever new services are run

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

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.

What fire rated sealant looks like in Gunville

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Gunville has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

For buildings such as St. Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Gunville is about 1 mile west of Newport, in the Isle of Wight. Gunville gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. 125 places in the Isle of Wight are on our list, large and small. For nearby work, see our Portsmouth page, about 13 miles away.

Common questions in Gunville

Do you work for hotels and guest houses in Gunville?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Do you cover smaller places like Gunville?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Will you assess my building’s fire safety?

No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

What’s the difference between intumescent and fire-rated sealant?

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.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little.

I’m a tenant. Can you help?

Of course. Check with your landlord; we can send the quote to them too.

When it is not the sealant

Before booking, it’s worth knowing the limits:

  • Doors that are not fire doors in the first place
  • Construction that doesn’t provide fire resistance on its own
  • Issuing a fire rating or certificate for a building

If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

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

For landlords and businesses

We also work for property managers and facilities teams. We can quote a run of properties together.

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

How we quote for fire rated sealant

For a quick quote, just ask. What matters most is:

  • Whether there’s mould to deal with
  • How many areas need sealing
  • How easy the joints are to reach
  • The type of sealant required

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Where the job is, and your postcode
  • Whether it has been sealed before
  • The type of property
  • What’s wrong with the joints now

Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Do you need fire rated sealant in Gunville?

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

These are the problems we are asked about most:

  • Unsealed gaps around fire door frames
  • Gaps flagged on a fire risk assessment
  • Fire seals that have cracked with movement
  • Open holes round services passing through fire walls

For site and facilities teams at buildings such as Carisbrooke College, gaps opened by contractors for new cabling are a common finding in schools and offices.

What to look for in a quote

  • Which sealant they’ll use, and why
  • Whether VAT is included
  • Who turns up on the day
  • How the joint is cleaned and prepared
