New build mastic in Norwood Green, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you are dealing with kitchen sealant that has pulled off the wall and smeared, uneven beads picked up at snagging, we can help, whatever the surface.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
There’s a 12-month guarantee on every job.

What new build mastic looks like in Norwood Green
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Southall station, it’s worth checking the sealant early, while snags are still fresh.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Record problems with dated pictures
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
