New build mastic in Lenzie, done properly
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. Common call-outs are for shower seals failing in the first year or two and sealant applied over dusty or wet surfaces, across skirting & floors, bathrooms & en suites and windows & doors.
Scottish towns like Lenzie have older streets and newer estates, with new homes still being built in many. New homes need their sealant and floor joints finished properly, and older ones need them renewing.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
New build mastic in Lenzie: local notes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Lenzie is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Around Lenzie, as everywhere, new build mastic is only as good as the preparation behind it.

When to call us in Lenzie
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
People normally contact us when they notice one of these:
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
If you’ve bought a new home near Lenzie station, the sealant around baths, showers and frames is worth checking in the first year or two.

- What guarantee comes with the work
- What insurance they hold
- What happens if they find a problem under the old sealant
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
- Wipe joints with warm soapy water
- Resist patching a failed seal with a tube from the DIY shop
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
