Fire rated sealant for Gurnard homes and businesses

How we handle fire rated sealant in Gurnard

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you’re dealing with gaps left after a refit or conversion and unsealed gaps where pipes and cables go through a wall, we can put it right, whatever the surface.

If you have holiday lets, a converted barn used for business or a community building near Gurnard, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Whatever the size of the job, it’s backed by our one-year guarantee.

Surface by surface

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing.

Fire rated sealant around Gurnard

If you run a hotel, guest house or holiday let in a coastal place like Gurnard, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Gurnard 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 All Saints' Church, older buildings that have had new heating or wiring often have service gaps worth checking.

How it works

We keep the work tidy and contained to the area we are working on. The job generally takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. In a small place like Gurnard, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  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 gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
  • Let us know about earlier repairs to the joints

Advice

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Tell trades working in the building that fire seals must be put back
  • Report cracked or damaged seals as soon as you notice them
  • Keep the record of products and locations with your fire safety documents
  • Include fire stopping when you schedule refits

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

What affects the quote in Gurnard

Every job gets its own quote. These are the things that affect it:

  • The type of sealant required
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • If someone has resealed it before
  • The type of property
  • Pictures of the joints, sent by email
  • What the problem is, such as mould, gaps, leaks or cracking

Need a quote? Please phone 0345 464 0079 or send us an email with a few details. You will know what we plan to do, and what it will cost, before any work begins.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

A DIY attempt does not rule out a professional job. We cut it out and start again.

For landlords and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

We also work for property managers and facilities teams in Gurnard and across the Isle of Wight. Several sites can be quoted together, and we’re fully insured.

Signs you need fire rated sealant in Gurnard

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.

Signs it’s time to call us include:

  • Gaps around pipes and cables through fire-resisting walls
  • Gaps where walls meet ceilings or slabs
  • Sealant items on a fire risk assessment action list
  • Seals cut through by electricians, plumbers or data installers

Managing a site like Gurnard Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Choosing a sealant specialist

FAQs for Gurnard

Do you cover smaller places like Gurnard?

Yes. Gurnard is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you take on hotel work around Gurnard?

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.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.

How long does fire rated sealant take?

It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Is it OK to seal over old sealant?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door leaf and its hardware need a door specialist.
