New build mastic for homes and businesses in Carndu
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on show homes, plot handovers and kitchens, and the jobs we see most are beads laid onto grit and dust from the build and worktop and upstand sealant coming away.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
You’re covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

How it works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Outside jobs in Carndu need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Let us know about earlier repairs to the joints
- Clear the area around the work

When to call us in Carndu
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
If you can see any of these, it’s time to have the joints looked at:
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
In and around Carndu, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

FAQs for Carndu
Will you come out to Carndu?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Stromeferry station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote with our 12-month guarantee.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Why has my new-build shower seal failed already?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Are you fully insured?
Yes. We’re fully insured.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When something else is needed
Before you book, it’s worth knowing the limits:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
- Settlement cracks that need a surveyor
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.
