New build mastic in Lennoxtown, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on bathrooms & en suites, windows & doors and show homes, and the jobs we see most are gaps between new skirting and floors and untidy sealant flagged on a snagging list.
For a place like Lennoxtown, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Looking after it afterwards
After the cure time, these simple habits help:
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Get a leaking seal dealt with straight away
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
Why deal with it now?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

- A 12-month guarantee on all work

Joints and finishes in Lennoxtown homes
Lennoxtown 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
Around Lennoxtown, as everywhere, new build mastic is only as good as the preparation behind it. 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 else we do in Lennoxtown
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The process
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the number of plots from start to finish. Somewhere like Lennoxtown may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
