Fire rated sealant in Kings Hill

About our fire rated sealant in Kings Hill

Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have old fire sealant that has split or come away and new service routes left unsealed after building work, we can put it right.

Community buildings, schools and small businesses around places like Kings Hill have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Signs you need fire rated sealant in Kings Hill

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Keep an eye out for these signs:

  • Seals cut through by electricians, plumbers or data installers
  • Fire seals that have cracked with movement
  • Gaps around pipes and cables through fire-resisting walls
  • Gaps where walls meet ceilings or slabs

Rented homes near West Malling station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

  • Whether they’re fully insured

Choosing a sealant specialist

Kings Hill questions

Do you work for landlords with property near West Malling station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Will you come out to Kings Hill?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.

Is intumescent sealant the same as fire-rated sealant?

Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Is there any odour?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Can you seal over the old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and you will get one quote.

Can I use normal mastic around a pipe through a fire wall?

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

What affects the quote in Kings Hill

The price is agreed before any work begins. It’s based on:

  • How much there is to do
  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.

What to tell us for a quote

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

  • Where the property is
  • A few pictures by email, if you can
  • Whether it has been sealed before
  • The type of property

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

How it works

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Kings Hill, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Before we arrive

  • Keep children and pets away from the work area
  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property

Advice

Why it’s worth doing now in Kings Hill

A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In an older home around Kings Hill, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

What the job involves on each surface

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment room by room.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.

What fire rated sealant looks like in Kings Hill

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.

If you look after a church, hall or community building such as Church of St John the Baptist, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Kings Hill School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
