New build mastic near Sparsholt

New build mastic in Sparsholt

Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. If you have skirting joints opening in the first winter and internal frame sealant that has split, we can put it right, on plot handovers, bathrooms & en suites and skirting & floors alike.

Somewhere as small as Sparsholt, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Every job comes with a 12-month guarantee.

Surface by surface

Windows and doors

Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.

Plot handovers

Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered as agreed.

How it works

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours in a single home in most cases. Somewhere like Sparsholt needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. New sealant suited to each joint is applied and tooled neatly.
  5. Finally, each room is checked and you’re given the cure time.

How to prepare

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height

Why it’s worth doing now in Sparsholt

Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, ring 0345 464 0079 or send us an email with pictures and we will give you a straight answer. Older cottages and farmhouses around Sparsholt can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What we’re called out for in Sparsholt

If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.

People normally contact us after spotting something like this:

  • New-build shower sealant that has already split
  • Joints pulling apart as timber shrinks
  • Internal frame sealant that has split
  • Second-fix sealing on new plots

In and around Sparsholt, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What your quote should include

  • What the quote includes, VAT included or not
  • How the surfaces are prepared before sealing
  • Which colour the sealant will be
  • Whether the sealant suits the joint

10 questions to ask before you book

DIY sealant or a professional job?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

  • Watch for new gaps as the house dries out
  • Act quickly if a seal starts to leak
  • Keep pictures and emails about snagging items
  • Follow the cure time we give you

Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.

Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
