Joints and finishes in Cardonald homes
The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
In and around Cardonald, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

About our new build mastic in Cardonald
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. If you have cracked sealant around new window and door frames and plot mastic for developers ahead of handover, we can help, whatever the surface.
Older tenement flats generally have timber floors on joists, so skirting joints open and close through the year. In Cardonald, a flexible sealant suits those joints better than filler.
Each job carries a 12-month guarantee, large or small.

Looking after it afterwards
So the new joints stay in good condition:
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.
Cardonald: your questions answered
Can you do new build mastic in Cardonald?
Yes. We work across all of Scotland, and Cardonald is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Is new build mastic in Cardonald guaranteed?
All our work, in Cardonald and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Where do you work from?
Mr Mastic is based in Crawley. We cover Cardonald and the rest of Glasgow, along with the rest of our area.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.

Related advice
What we’re called out for in Cardonald
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Any of these means the joints need attention:
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
If you’ve bought a new home near Hillington East station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why it’s worth doing now in Cardonald
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Private landlords in Cardonald must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
