About our new build mastic in Carntyne
Across Carntyne, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on show homes, windows & doors and skirting & floors, and people most often call us about joints pulling apart as timber shrinks and shower seals failing in the first year or two.
Scotland’s cities are still adding new flats and houses, and in new homes, sealant and floor joints are often among the first snags.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Different surfaces, different methods
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors to the agreed spec.
What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Questions from Carntyne
Can you help a landlord with a rental near Carntyne station?
Yes. We work for letting agents and landlords as well as homeowners. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
What guarantee comes with new build mastic in Carntyne?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.

What else we do in Carntyne
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on the number of plots. For a tenement in Carntyne, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

New homes and floors in Carntyne
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. Carntyne 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.

What we are called out for in Carntyne
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
Around Carntyne, as everywhere, new build mastic is only as good as the preparation behind it.
