New build mastic in Winchelsea, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on bathrooms & en suites, show homes and kitchens, and people most often call us about joints pulling apart as timber shrinks and worktop and upstand sealant coming away.
Around Winchelsea, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by our one-year guarantee, wherever you are in East Sussex.

Common problems we fix in Winchelsea
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
The problems people usually mention when they call include:
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
- Sealant that never bonded to the surface
For new homes near Winchelsea station, it’s worth checking the sealant early, while snags are still fresh.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Check bath and shower seals every few months as the house settles
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
