Why act early in Leachkin
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. 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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Sand mastic in Leachkin
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. We work on sash and case windows, brick reveals and timber door frames, and people most often call us about cracked mastic round a front door frame and draughts and rain around sash boxes.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.

How to look after the new joints
After the cure time, these simple habits help:
- Clear gutters so water doesn’t pour onto the windows
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Keep modern sealant off the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
What sand mastic looks like in Leachkin
Leachkin is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Rented homes near Inverness station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Inverness High School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows for a typical job. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
