How we handle new build mastic in Ashey
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. We work on skirting & floors, windows & doors and show homes, and common reasons people get in touch are leaking shower tray seals in a new home and sealant applied over dusty or wet surfaces.
Somewhere as small as Ashey, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, in Ashey and everywhere else we cover.

New build mastic around Ashey
Ashey is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. 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.
In and around Ashey, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Ashey is about 2 miles south-west of Ryde, in the Isle of Wight. Anywhere in PO33, our applicators can take on new build mastic. Ashey is one of 125 towns and villages in the Isle of Wight we cover. You can also see our page for Portsmouth, roughly 9 miles from Ashey.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Where a wall is exposed, as many are in small places like Ashey, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
- Avoid scourers and strong chemicals on sealant
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
