Strathmartine New Build Mastic
Our applicators work in Strathmartine on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
How we handle new build mastic in Strathmartine
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant normally lacks. We work on bathrooms & en suites, plot handovers and show homes, and people most often call us about sealant applied over dusty or wet surfaces and gaps between new skirting and floors.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
You’re covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Strathmartine: your questions answered
Is Strathmartine within the area you cover?
Yes, Strathmartine is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Strathmartine in your area for new build mastic?
Yes, Strathmartine is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we’ll say so.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.

What happens if it’s left?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us
- Any old sealant cut out fully, not covered over

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours in a single home. Outdoor work around Strathmartine depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

Related advice
When to call us in Strathmartine
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.
Look out for any of the following:
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
Around Strathmartine, as everywhere, new build mastic is only as good as the preparation behind it.

When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep pictures and emails about snagging items
- Get a leaking seal dealt with straight away
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
