Fire rated sealant near High Easter

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

About our fire rated sealant in High Easter

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We’re often asked to deal with old fire sealant that has split or come away and gaps filled with a product that isn’t fire-rated, across flats & HMOs, pipe & cable gaps and door frames.

If you have holiday lets, a converted barn used for business or a community building near High Easter, 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 12-month guarantee in High Easter and across Essex.

What affects the cost of fire rated sealant

Call for a quick quote. What matters most is:

  • Working hours on commercial sites
  • How easy the joints are to reach
  • Whether there’s mould to deal with
  • How much there is to do

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

What happens on the day

We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on how many gaps there are. In a small place like High Easter, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
  • Plan for the work area to be out of bounds to pets and children

Advice

Surface by surface

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.

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.

Common problems we fix in High Easter

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

Signs it’s time to call us include:

  • Gaps where walls meet ceilings or slabs
  • Damaged fire sealant left by other trades
  • New service routes left unsealed after building work
  • Sealant items on a fire risk assessment action list

In and around High Easter, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Questions to ask before you book

  • Whether you can choose the colour
  • The length of the guarantee
  • How long to leave it before use
  • Which sealant they’ll use, and why

How to look after the new joints

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

  • Make resealing part of every contractor’s brief
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Take pictures of fire stopping before ceilings or boxing go back
  • Check whether a sealant can be painted before decorating over it

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

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

What fire rated sealant looks like in High Easter

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

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

High Easter: your questions answered

Do you cover High Easter for fire rated sealant?

Yes, High Easter is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Is High Easter within the area you cover?

Yes, High Easter is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

What does intumescent mean?

An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.

Can you tell me how many minutes the seal will last?

We don’t give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.

Are you fully insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Does someone need to be in?

We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
