New build mastic in Princelett

What we can’t put right

Sealant isn’t the answer to every problem, and we will tell you before we start. It will not solve:

  • Movement caused by a poorly fitted tray or bath
  • Settlement cracks that need a surveyor
  • Plumbing faults behind the sealant

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

New build mastic in Princelett

We work in new homes and on new-build sites across Princelett. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Common call-outs are for frame joints opening as the plaster dries and plot mastic for developers ahead of handover, on kitchens, show homes and skirting & floors.

In a village or hamlet like Princelett, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

Our work is backed for twelve months, in Princelett and everywhere else we cover.

Should I try it myself first?

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

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Check bath and shower seals every few months as the house settles
  • Raise failed sealant with the developer while you are covered
  • Avoid running a DIY bead over the old one
  • Act quickly if a seal starts to leak

Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.

Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you so report it promptly.

What new build mastic looks like in Princelett

Princelett is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For new homes near Shanklin station, it’s worth checking the sealant early, while snags are still fresh. In and around Princelett, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.

Where is Mr Mastic based?

That depends on the sealant. Some smell for a while, some hardly at all.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

What the job involves on each 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 that suits the frame.

Kitchens

New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.

Leave it or put it right?

A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Around Princelett, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Princelett needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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. Each area is checked and left with its cure time.

How to prepare

  • Mention any tricky access
  • Try not to wet indoor joints just before the visit
  • Clear the area around the work
