New build mastic in Tealing, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with cracked sealant around new window and door frames and untidy sealant flagged on a snagging list, we can put it right.
Work in a place like Tealing is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Whatever the size of the job, it’s backed by our 12-month guarantee in Tealing and across Dundee.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What new build mastic looks like in Tealing
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
In and around Tealing, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Tealing itself or nearby, the right material for each joint matters as much as a neat finish.

My new home is still under warranty. Should I contact you?

What does new build mastic cost?
Every job is different, so each one gets its own quote. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.

Why it’s worth doing now in Tealing
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. 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.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- Full insurance on every job

Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.

- Each area is checked and left with its cure time.
