New Build Mastic in Westerwood
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Westerwood and across North Lanarkshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
The process
Once we’re 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. For a place like Westerwood, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Mention any tricky access
- Tell us if parking is tricky
- Mention if the joints have been sealed before

How we handle new build mastic in Westerwood
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Common call-outs are for plot mastic for developers ahead of handover and skirting joints opening in the first winter, on windows & doors, kitchens and skirting & floors.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.

Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- The rough size of the job

We don’t publish a price list. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What we can’t put right
It helps to know what we cannot do:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
