Fire rated sealant in Grain, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Typical jobs include seals cut through by electricians, plumbers or data installers and standard silicone or caulk in a fire-stopping gap, on door frames, pipe & cable gaps and flats & HMOs.

In a village or hamlet like Grain, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

There’s a 12-month guarantee on every job, whatever its size.

Grain questions

Do you cover Grain for fire rated sealant?

Yes. We work across London and the South East, and Grain is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.

Is Grain within the area you cover?

Yes. Grain is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.

What does fire rated sealant cost?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

Do you have insurance?

Yes. We are fully insured, and we can confirm the details when we quote.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Do you seal gaps around fire door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame, and we’ll mention anything we notice about the door.

How long does the job take?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.

Surface by surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.

When to call us in Grain

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

Common reasons people contact us are:

  • Ordinary sealant used where a fire-rated product was needed
  • Sealant items on a fire risk assessment action list
  • Gaps left after a refit or conversion
  • Cracked or shrunken fire-rated sealant

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

Our hiring checklist

The process

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. For a village or hamlet like Grain, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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 faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

Getting ready for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any tricky access
  • Let us know about parking restrictions

Workplaces and buildings in Grain

For seaside hotels, guest houses and holiday lets around Grain, 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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Schools such as St James Church of England Primary Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Sheerness-On-Sea station, any gap left by new services in shared walls should be closed with a fire-rated product.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Allow for resealing whenever new services are run
  • Look in service cupboards and ceiling voids from time to time
  • Report cracked or damaged seals as soon as you notice them
  • Photograph sealed gaps before they’re covered up

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so the item can be closed.

When it isn’t the sealant

New sealant can’t fix everything, and we’ll tell you before work begins. Sealant won’t put right:

  • Construction that does not provide fire resistance on its own
  • Openings too large for sealant, which need batts, boards or another system
  • Fire risk assessments, which need a qualified assessor

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
