New build mastic in High Hurstwood
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on plot handovers, bathrooms & en suites and skirting & floors, and the jobs we see most are beads laid onto grit and dust from the build and internal frame sealant that has split.
Somewhere as small as High Hurstwood, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What new build mastic looks like in High Hurstwood
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around High Hurstwood, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Buxted station, it’s worth checking the sealant early, while snags are still fresh.

Advice
What we cannot put right
To be straight with you, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.
What we seal
- Windows & doors
- Plot handovers
- Bathrooms & en suites
- Show homes
- Kitchens
- Skirting & floors
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Older cottages and farmhouses around High Hurstwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.
