How we handle new build mastic in Kirkcolm
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. If you are dealing with sealant work across a run of new homes and sealant applied over dusty or wet surfaces, we can put it right.
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.
Each job carries a 12-month guarantee, whatever its size.

Advice
What new build mastic looks like in Kirkcolm
Kirkcolm is close to 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. Kirkcolm 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.
In and around Kirkcolm, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Stranraer station, the sealant around baths, showers and frames is worth checking in the first year or two.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Open a window or run the fan after bathing
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, email us at info@mrmastic.co.uk with photos and we’ll tell you. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Common questions in Kirkcolm
I let a flat near Stranraer station. Can you help?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Can you do new build mastic in Kirkcolm?
Yes, Kirkcolm is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
How do I get a quote for new build mastic in Kirkcolm?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
