New build mastic in Frant, 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 since hurried prep is behind a lot of new-build failures. Typical jobs include skirting joints opening in the first winter and beads laid onto grit and dust from the build, on show homes, windows & doors and kitchens.
Older homes in small places like Frant often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months.

Joints and finishes in Frant homes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Frant station, it’s worth checking the sealant early, while snags are still fresh.

How the job changes by surface

Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.

Signs you need new build mastic in Frant
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Any of these means the joints need attention:
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
- Worktop and upstand sealant coming away
- Sealant applied over dusty or wet surfaces
Around Frant, as everywhere, new build mastic is only as good as the preparation behind it.

Somewhere like Frant needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.

- The finished joints are checked and the cure times given.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Around Frant, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
