New Build Mastic in Dunure
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Dunure and across South Ayrshire. Fully insured, ARBOMaster approved and guaranteed for a year.

- Gaps behind new kitchen upstands
- New-build shower sealant that has already split
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
New build mastic in Dunure, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. We work on windows & doors, plot handovers and kitchens, and common reasons people get in touch are cracked sealant around new window and door frames and cracks appearing as a new home settles.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Signs you need new build mastic in Dunure
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
The problems people generally mention when they call include:
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Maybole station, the sealant around baths, showers and frames is worth checking in the first year or two.

Joints and finishes in Dunure homes
Dunure is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Dunure, as everywhere, new build mastic is only as good as the preparation behind it.

Advice
What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t seal over failed sealant yourself
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Avoid scourers and strong chemicals on sealant
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
