Joints and finishes in Stevenston homes
Stevenston is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Stevenston is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
For new homes near Stevenston station, it’s worth checking the sealant early, while snags are still fresh.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep water off fresh sealant until it has cured
- Keep photos and emails about snagging items
- Act quickly if a seal starts to leak
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
