Fire rated sealant in Holywell

Fire rated sealant in Holywell

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you’re dealing with open joints along the top of partitions and fire stopping disturbed by later work, we can put it right.

Around a place like Holywell, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the cost of fire rated sealant

You’ll get a clear quote before we start. It takes into account:

  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows
  • Working hours on commercial sites

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The type of property
  • Any access issues, like height or stairs
  • Any previous sealing or DIY work
  • The address or postcode of the job

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

For landlords and businesses

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Leave it or put it right?

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around Holywell, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What fire rated sealant looks like in Holywell

For seaside hotels, guest houses and holiday lets around Holywell, 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. 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’re given, installing the product to its tested details.

For buildings such as St John the Evangelist, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as St John's Meads Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

Do you work in hotels near Holywell?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Are you fully insured?

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

How long does the job take?

Most jobs take from a few hours to a few days, depending on the number of gaps and the access, including the preparation. Your quote will say how long we expect yours to take.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Do you certify the fire stopping?

Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

Is it OK to seal over old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Can you give us a record of the work?

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

Signs you need fire rated sealant in Holywell

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.

Most people get in touch when they notice one of these:

  • Open holes round services passing through fire walls
  • Sealant items on a fire risk assessment action list
  • Fire stopping disturbed by later work
  • Gaps left after a refit or conversion

If you let a flat or house near Eastbourne station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Our hiring checklist

Different surfaces, different methods

Door frames

Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length.

What we do, step by step

We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. In a smaller place like Holywell, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. Access to each area is agreed so the work can run in order.
  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Before we arrive

  • Mention any parking rules near the property
  • On commercial sites, let us know about site rules
  • For indoor joints, keep the area dry beforehand if you can
