How we handle new build mastic in Barcombe

Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We work on show homes, kitchens and plot handovers, and common reasons people get in touch are sealant work across a run of new homes and sealant that never bonded to the surface.

For a small place like Barcombe, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What the job involves on each surface

Kitchens

As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.

Show homes

Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.

How it works

You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a village or hamlet like Barcombe, 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. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

How to prepare

  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit
  • Move anything stored near the joints

Related advice

Why deal with it now?

For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Barcombe can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Why us?

  • Trusted Arbo and Everbuild sealants
  • Anti-fungal sanitary silicone in wet areas
  • Neat joints and a tidy finish
  • We agree the colour with you first

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Barcombe: your questions answered

Do you cover smaller places like Barcombe?

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.

Can you help a landlord with a rental near Cooksbridge station?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Are you insured?

Yes. We are fully insured for domestic and commercial work.

Can new sealant go on top of the old bead?

No. We always remove the existing bead, then clean and prime the joint, before resealing.

Can I send you my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.

How do I get a quote for new build mastic in Barcombe?

Size, access and the old material all affect the cost. Ask us for a quote.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Where are you based?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

When to call us in Barcombe

Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.

Signs it’s time to call us include:

  • Cracked sealant around new window and door frames
  • Smeared, uneven beads picked up at snagging
  • Plot mastic for developers ahead of handover
  • Worktop and upstand sealant coming away

If you’ve bought a new home near Cooksbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

What to look for in a quote

  • When the joint can take water or movement
  • Whether VAT is included
  • Which sealant they’ll use, and why
  • Whether all the old sealant comes out first
