Why act early in Lennie
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. 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.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

New build mastic for homes and businesses in Lennie
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have cracked sealant around new window and door frames and untidy sealant flagged on a snagging list, we can help, whatever the surface.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Our work is backed for twelve months, in Lennie and everywhere else we cover.

What the job involves on each surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
Joints and finishes in Lennie homes
Lennie is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
In and around Lennie, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When to call us in Lennie
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 and can tear.
The most common problems we see are:
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
If you’ve bought a new home near Edinburgh Gateway station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- Which colour the sealant will be
- How much experience the applicator has
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for property managers and facilities teams in Lennie and across Edinburgh. Several sites can be quoted together, and we are fully insured for the work.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- The old material and how stubborn it is
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

Is Lennie within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will you just run a new bead over the existing one?
