Sand mastic for homes and businesses in Comrie
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include window mastic to renew ahead of painting and a silicone bead on a sash window that spoils the look, across brick reveals, period & listed homes and stone surrounds.
Mastic can only go onto a dry joint, so outside work in Comrie depends on the weather. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- How we’d reach the joints
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
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.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Check with your local planning authority if your home is listed
- Avoid patching sand mastic with silicone
- Check the mastic when you check the paintwork
- Do not paint over the new mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

The work is kept neat and contained to the joints we’re treating, so you can carry on as normal.

Let us know how to find you and how to reach the joints, and the visit is planned around that.

Windows and doors in Comrie
Comrie is close to 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.
In the older streets around Church of The Most Holy Name, the joint between an old wall and a newer frame is usually the first place rain gets in.
