New build mastic in Thornliebank
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. We work on bathrooms & en suites, kitchens and plot handovers, and the jobs we see most are sealant that never bonded to the surface and cracked sealant around new window and door frames.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. In Thornliebank, we cover those floor joints as well as plot mastic for developers.
You get a 12-month guarantee, the same in Thornliebank as everywhere else we work.

Common problems we fix in Thornliebank
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Common reasons people contact us are:
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Sealant applied over dusty or wet surfaces
Around Thornliebank, as everywhere, new build mastic is only as good as the preparation behind it.

Why it’s worth doing now in Thornliebank
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Thornliebank, damp can travel a long way before it shows.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.

Your quote is based on your job. We look at:

Common questions in Thornliebank
I let a flat near Whitecraigs station. Can you help?
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 give you a clear price.
Is new build mastic in Thornliebank guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
How do I get a quote for new build mastic in Thornliebank?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
What new build mastic looks like in Thornliebank
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
For new homes near Whitecraigs station, it’s worth checking the sealant early, while snags are still fresh.
