New build mastic in North Leigh

How it works

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots from start to finish. Somewhere as small as North Leigh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your snagging list or plot schedule with you.
  2. The old bead comes out in full, with no layer left behind.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. Each area is checked and left with its cure time.

Before we arrive

  • Clear items away from the joints we’re working on
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know if you’ve seen damp or leaks

Advice

How we handle new build mastic in North Leigh

New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on plot handovers, windows & doors and kitchens, and people most often call us about untidy sealant flagged on a snagging list and shower seals failing in the first year or two.

Work in a small place like North Leigh just needs the journey and access planning, and once on site, the job is the same as anywhere.

Every job is covered by our one-year guarantee, wherever you are in Oxfordshire.

Questions from North Leigh

Can you do new build mastic in North Leigh?

Yes. Our work covers London and the South East, and North Leigh is part of that. Just call 0345 464 0079 or email us with a few details of the job.

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

Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.

Why does sealant fail so quickly in new builds?

A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.

Do you take on second-fix sealing for builders?

Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Are you an approved applicator?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Should I go to my builder first?

Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we are happy to quote with our one-year guarantee.

Work for landlords, hotels and businesses

For anyone letting property in or around North Leigh, several properties can go on one quote. Send us the addresses and the work at each.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Resist patching a failed seal with a tube from the DIY shop
  • Wait for the cure time before using a resealed shower
  • Don’t wait for the house to settle if water is getting through
  • Ventilate bathrooms well, especially in the first year

Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Why act early in North Leigh

Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. Where a wall is exposed, as many are in small places like North Leigh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

Quotes for new build mastic in North Leigh

The quote reflects the job in front of us. We take into account:

  • How many areas need sealing
  • How much there is to do
  • How easy the joints are to reach
  • The product the joint needs

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking
  • A few photos by email, if you can
  • If it’s domestic, commercial or a hotel

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Signs you need new build mastic in North Leigh

Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.

Keep an eye out for any of the following:

  • Joints pulling apart as timber shrinks
  • Messy sealant that spoils new finishes
  • Sealant that never bonded to the surface
  • Kitchen sealant that has pulled off the wall

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