New build mastic in Gateside
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on plot handovers, bathrooms & en suites and kitchens, and the jobs we see most are smeared, uneven beads picked up at snagging and beads laid onto grit and dust from the build.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
There’s a 12-month guarantee on every job.

What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, send an email to info@mrmastic.co.uk with photos and we’ll give you a straight answer. In an older home around Gateside, damp from a failed joint can get into timber and plaster.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Your questions about new build mastic in Gateside
Do you work for landlords with property near Glengarnock station?
Yes. We work for landlords and letting agents as well as householders. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you cover Gateside for new build mastic?
Yes, Gateside is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Landlord and commercial work in Gateside
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Joints and finishes in Gateside homes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. The west of Scotland 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 Glengarnock station, it’s worth checking the sealant early, while snags are still fresh.

When to call us in Gateside
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
Common reasons people contact us include:
- Beads laid onto grit and dust from the build
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
In and around Gateside, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
