How we handle new build mastic in Arnprior
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on kitchens, bathrooms & en suites and plot handovers, and the jobs we see most are beads laid onto grit and dust from the build and second-fix sealing on new plots.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
Whatever the size of the job, it’s backed by our 12-month guarantee in Arnprior and across Stirling.

Why it’s worth doing now in Arnprior
The builder is normally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

New build mastic in Arnprior: local notes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Arnprior 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 jobs in and around Arnprior, choosing the right material for each joint is as important as a tidy finish.

Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Common problems we fix in Arnprior
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Most people get in touch after spotting one of these:
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
- Untidy sealant flagged on a snagging list
Around Arnprior, as everywhere, new build mastic is only as good as the preparation behind it.
