About our new build mastic in Preston Crowmarsh

Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Typical jobs include new-build shower sealant that has already split and messy sealant that spoils new finishes, on windows & doors, plot handovers and skirting & floors.

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

A 12-month guarantee comes as standard.

Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.

  • Untidy sealant flagged on a snagging list
  • Cracks appearing as a new home settles
  • Cracked sealant around new window and door frames
  • Beads laid onto grit and dust from the build

Around Preston Crowmarsh, as everywhere, new build mastic is only as good as the preparation behind it.

FAQs for Preston Crowmarsh

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

Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Do you cover smaller places like Preston Crowmarsh?

Yes, Preston Crowmarsh is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you hold any approvals?

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

Where do you work from?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Do you do commercial work?

Yes. We can plan bigger jobs in stages to suit the site.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.

Is it worth resealing while the house is still settling?

Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

Why it’s worth doing now in Preston Crowmarsh

If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Preston Crowmarsh can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

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

Why us?

  • You choose the colour before work begins
  • Sealant colour chosen to suit
  • Homes, businesses and hotels
  • Tidy, careful work

What we do, step by step

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. Somewhere as small as Preston Crowmarsh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  3. Joints are dried and primed where the product calls for it.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. We check every joint and leave you with the cure times.
