Fire rated sealant for Chartham Hatch homes and businesses

What fire rated sealant looks like in Chartham Hatch

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.

For landlords with property near Chartham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as The Canterbury Academy, service openings in fire-resisting walls need checking after any refurbishment.

How we handle fire rated sealant in Chartham Hatch

Intumescent sealant looks much like any other sealant until it gets hot; 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. We work on door frames, pipe & cable gaps and plasterboard & masonry, and people most often call us about gaps flagged on a fire risk assessment and gaps around pipes and cables through fire-resisting walls.

For a small place like Chartham Hatch, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

Whatever the size of the job, you get the same 12-month guarantee in Chartham Hatch and across Kent.

What affects the cost of fire rated sealant

Call for a quick quote. What matters most is:

  • How many rooms, windows or areas are involved
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • The number and length of the joints

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • Pictures of the joints, sent by email
  • How many joints, rooms or windows are involved

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.

Surface by surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.

How the visit works

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Chartham Hatch, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your records.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts

Getting a quote

We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, phone 0345 464 0079 or email us.

For landlords and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.

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

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. Older cottages and farmhouses around Chartham Hatch can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Keeping the joints in good condition

Looking after new joints is easy:

  • Take photos of fire stopping before ceilings or boxing go back
  • Get damaged fire seals looked at promptly
  • Keep the record of products and locations with your fire safety documents
  • Check risers, ceiling voids and cupboards during building checks

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Your questions about fire rated sealant in Chartham Hatch

I let a flat near Chartham station. Can you help?

Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

Do you cover Chartham Hatch for fire rated sealant?

Yes, Chartham Hatch is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.

Can I add another job to the visit?

Yes. Just list everything you need and we will quote it together.

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.

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

That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Do you carry out fire risk assessments?

No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.

When to call us in Chartham Hatch

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

The problems people generally mention when they call are:

  • Holes left by a change of layout
  • Fire seals that have cracked with movement
  • Standard silicone or caulk in a fire-stopping gap
  • Joints picked up in a fire-stopping survey

If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

What your quote should include

  • How the surfaces are prepared before sealing
  • Whether they seal over old material or remove it
  • Is VAT in the price?
  • What happens if they find a problem under the old sealant
