New build mastic in Lochwinnoch, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you’re dealing with skirting joints opening in the first winter and leaking shower tray seals in a new home, we can help.
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.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

Other services in Lochwinnoch
Do you need new build mastic in Lochwinnoch?
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Keep an eye out for any of the following:
- Sealant work across a run of new homes
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Lochwinnoch station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- How the surfaces are prepared before sealing
- How long the guarantee is
- What product goes in the joint
- What the quote includes, VAT included or not
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Do not seal over failed sealant yourself
- Keep photos and emails about snagging items
- Follow the cure time we give you
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
How we quote for new build mastic

- The type of property
- The address or postcode of the job

The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Around Lochwinnoch, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

FAQs for Lochwinnoch
Do you cover Lochwinnoch for new build mastic?
Yes, Lochwinnoch is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Lochwinnoch station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish and agree it with you.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. If it isn’t resolved, we will cut it out and reseal it.
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.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. Not sure whether yours can wait? You can send an email to info@mrmastic.co.uk with a few photos. 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.

New build mastic around Lochwinnoch
Lochwinnoch 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. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
