What new build mastic looks like in Hythe
Hythe is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. The South East is one of 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 Sandling station, it’s worth checking the sealant early, while snags are still fresh.
Hythe is about 4 miles west of Folkestone, in Kent. Hythe gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 922 towns and villages across Kent, large and small. There’s also a page for Chelmsford, about 53 miles away.
Here we cover the CT21 postcode area for new build mastic. Whether your property is on High Street, Church Road and Station Road or anywhere close by, our applicators can take on the job.

New build mastic in Hythe, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on show homes, windows & doors and skirting & floors, and the jobs we see most are untidy sealant flagged on a snagging list and internal frame sealant that has split.
Small business units and shops in a town like Hythe have floors that take heavy wear. Threshold and floor joints are best resealed before their edges start breaking away.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Keeping the joints in good condition
Looking after new joints is easy:
- Ventilate bathrooms well, especially in the first year
- Keep photos and emails about snagging items
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we’ll cut it out and reseal it.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How long does the job take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer, and we will tell you how long to expect.

Advice
Signs you need new build mastic in Hythe
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
If you can see any of these, it’s time to have the joints looked at:
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
Around Hythe, as everywhere, new build mastic is only as good as the preparation behind it.
