New build mastic in Shalden Green, done properly

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. We work on kitchens, show homes and skirting & floors, and common reasons people get in touch are messy sealant that spoils new finishes and gaps opening as the house dries out and settles.

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

All of our work is guaranteed for twelve months, in Shalden Green and everywhere else we cover.

When something else is needed

To be straight with you, some problems need a different trade:

  • Structural cracks in walls or ceilings
  • Movement caused by a poorly fitted tray or bath
  • Plumbing faults behind the sealant

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

What we seal

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

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

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

Size, access and the old material all affect the cost. Call for a quick quote.

How long does the job take?

A typical job takes a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. We will confirm how long when we quote.

Why does sealant fail so quickly in new builds?

Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.

Can you quote for more than one area?

Yes. More than one area can be quoted together.

Can I send you my snagging list?

Yes. Send the list and a few photos of the sealant items and we will give you a quote. We’ll tell you if anything on it is not a sealant job.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Why it’s worth doing now in Shalden Green

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Shalden Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.

What you get with us

  • White, clear, grey or another colour, product permitting
  • We agree the colour with you first
  • We leave the area clean and tidy
  • Full insurance on every job

Do you need new build mastic in Shalden Green?

Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.

Keep an eye out for these signs:

  • Smeared, uneven beads picked up at snagging
  • Second-fix sealing on new plots
  • Kitchen sealant that has pulled off the wall
  • Cracked sealant around new window and door frames

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