New build mastic for homes and businesses in Hythe
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. Typical jobs include internal frame sealant that has split and leaking shower tray seals in a new home, on show homes, windows & doors and kitchens.
Towns like Hythe have older streets and newer estates side by side, with new homes still going up on the edge of many towns. Whether a house is brand new or a few years old, sealant and floor joints are often the first snags to show.
You get a one-year guarantee, the same in Hythe as everywhere else we work.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
- Wipe joints with warm soapy water
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.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

New homes and floors in Hythe
Hythe is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Southampton Town Quay station, it’s worth checking the sealant early, while snags are still fresh.

What affects the quote in Hythe
Your quote is based on your job. We take into account:
- Whether the work is at height

- Where the job is, and your postcode

What we’re called out for in Hythe
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
In and around Hythe, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- What preparation is included
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- Is VAT in the price?
