Common problems we fix in Carter's Clay

Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

The most common problems we see are:

  • Unsealed gaps around fire door frames
  • Joints picked up in a fire-stopping survey
  • Ordinary sealant used where a fire-rated product was needed
  • Cracked or shrunken fire-rated sealant

Managing a site like Awbridge Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Questions to ask before you book

  • Are they insured?
  • Who turns up on the day
  • The length of the guarantee
  • How the surfaces are prepared before sealing

Choosing a sealant specialist

Fire rated sealant in Carter's Clay, done properly

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you have damaged fire sealant left by other trades and gaps filled with a product that isn’t fire-rated, we can help.

Work in a small place like Carter's Clay is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Fire rated sealant around Carter's Clay

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you let a flat or house near Mottisfont & Dunbridge station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Why act early in Carter's Clay

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Older cottages and farmhouses around Carter's Clay can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • File the fire-stopping record where your assessor can find it
  • Check whether a sealant can be painted before decorating over it
  • Tell trades working in the building that fire seals must be put back
  • Allow for resealing whenever new services are run

Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Common questions in Carter's Clay

Do you cover smaller places like Carter's Clay?

Yes. Carter's Clay is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work for landlords with property near Mottisfont & Dunbridge station?

Yes, we work for landlords and letting agents. You can call 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.

How long does fire rated sealant take?

Most jobs take a few hours for a handful of gaps, and longer for a whole building, including the preparation. Your quote will say how long we expect yours to take.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we’ll quote it together.

Will you assess my building’s fire safety?

No. We follow the requirements from your assessor, designer or building control.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Can I do it myself?

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.

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.

How the job changes by surface

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length.

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

What happens on the day

On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Carter's Clay, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Clear the area around the work
  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints
