Need fire rated sealant in Abshot?

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

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, and the work is guaranteed for a year.

Fire rated sealant for homes and businesses in Abshot

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. If you are dealing with open joints along the top of partitions and seals cut through by electricians, plumbers or data installers, we can put it right, whatever the surface.

For a small place like Abshot, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

You get a one-year guarantee, the same in Abshot as everywhere else we work.

FAQs for Abshot

Do you cover smaller places like Abshot?

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

Do you work for landlords with property near Swanwick station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.

Will the old sealant be removed?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Do you take on fire stopping in schools and offices?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Early starts or out-of-hours work can be arranged if that suits the building.

Will you assess my building’s fire safety?

No. We work from the specification you give us, and apply each product to its tested details.

How long does fire rated sealant take?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer.

Does someone need to be in?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

When something else is needed

In fairness, some problems need a different trade:

  • Issuing a fire rating or certificate for a building
  • Construction that does not provide fire resistance on its own
  • Problems with the door itself rather than the gap around the frame

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • The number and length of the joints
  • The product the joint needs
  • The number of rooms or windows
  • Whether there’s mould to deal with

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What we need to know

To help us quote quickly, let us know:

  • Any access issues, like height or stairs
  • The type of property
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved

To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.

What we are called out for in Abshot

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.

Most people get in touch after spotting something like this:

  • Cracked or shrunken fire-rated sealant
  • Open joints along the top of partitions
  • Joints picked up in a fire-stopping survey
  • Standard silicone or caulk in a fire-stopping gap

Community buildings like St John are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Before you book anyone

  • Whether all the old sealant comes out first
  • Who turns up on the day
  • How the surfaces are prepared before sealing
  • What product goes in the joint

Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.

Fire rated sealant in Abshot: local notes

For seaside hotels, guest houses and holiday lets around Abshot, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.

If you let a flat or house near Swanwick station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For site and facilities teams at buildings such as Locks Heath Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.

The process

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Abshot, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  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. We record what was done and flag anything that needs a different system.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Mention any parking rules near the property
  • Where the joints are inside, avoid wetting them before we arrive
