New build mastic for homes and businesses in Wannock
Dust is the enemy of 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. We work on windows & doors, show homes and plot handovers, and common reasons people get in touch are gaps behind new kitchen upstands and gaps opening as the house dries out and settles.
Work in a small place like Wannock just needs the journey and access planning, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee.

New build mastic in Wannock: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Honest limits
New sealant can’t fix everything, and we’ll tell you before any work starts. It won’t solve:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Skirting & floors
- Plot handovers
- Kitchens
- Windows & doors
- Show homes
- Bathrooms & en suites
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
- Record problems with dated photos
Watch the joints as the house settles. Small gaps can appear as the house dries.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
Why act early in Wannock
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. Older cottages and farmhouses around Wannock 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 much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
