- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands

- Untidy sealant flagged on a snagging list

New build mastic in Gadshill
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on windows & doors, show homes and bathrooms & en suites, and the jobs we see most are gaps opening as the house dries out and settles and sealant work across a run of new homes.
In a village or hamlet like Gadshill, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Your job is guaranteed for a year, as with all our work.

What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Is there a guarantee?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

What else we do in Gadshill
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Gadshill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear quote for the lot.

For a village or hamlet like Gadshill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
