New build mastic for Laverstoke homes and businesses

New build mastic in Laverstoke, done properly

Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. If you have joints pulling apart as timber shrinks and shower seals failing in the first year or two, we can put it right, on kitchens, skirting & floors and plot handovers alike.

Around Laverstoke, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

Whatever the size of the job, it’s backed by our one-year guarantee in Laverstoke and across Hampshire.

Aftercare tips

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

  • Check bath and shower seals every few months as the house settles
  • Get a leaking seal dealt with straight away
  • Report sealant problems to your builder during the snagging period
  • Wipe joints with warm soapy water

Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

How it works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. In a small place like Laverstoke, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely down to clean surfaces.
  3. Joints are vacuumed and cleaned of building dust.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. We tool every joint neatly and tell you when each area can be used.

Advice

Questions from Laverstoke

Do you cover Laverstoke for new build mastic?

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

I let a flat near Whitchurch (Hampshire) station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Which products do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Will you just run a new bead over the existing one?

No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.

Will it make a mess?

No. The area is protected while we work and cleaned up afterwards.

Why does sealant fail so quickly in new builds?

Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you need new build mastic in Laverstoke?

The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.

Most people get in touch when they notice one of these:

  • Shower seals failing in the first year or two
  • Second-fix sealing on new plots
  • Beads laid onto grit and dust from the build
  • Gaps opening as the house dries out and settles

For new homes near Whitchurch (Hampshire) station, it’s worth checking the sealant early, while snags are still fresh.

What your quote should include

  • When the joint can take water or movement
  • What insurance they hold

10 questions to ask before you book

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

What we can’t put right

Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:

  • Deciding who is responsible under a builder’s warranty
  • Settlement cracks that need a surveyor
  • Leaking fittings rather than failed sealant

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

Joints and surfaces we work on

  • Plot handovers
  • Bathrooms & en suites
  • Skirting & floors
  • Kitchens
  • Windows & doors
  • Show homes

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.
