New build mastic in Ardentinny, 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 plot handovers, show homes and skirting & floors, and common reasons people get in touch are gaps opening as the house dries out and settles and internal frame sealant that has split.
For a place like Ardentinny, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Joints and finishes in Ardentinny homes
Ardentinny 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. Ardentinny is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
Around Ardentinny, as everywhere, new build mastic is only as good as the preparation behind it.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
- Do not wait for the house to settle if water is getting through
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Common problems we fix in Ardentinny
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
Any of these means the joints need attention:
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
For new homes near Garelochhead station, it’s worth checking the sealant early, while snags are still fresh.
