Sand mastic for sash & case windows in Tillicoultry, Clackmannanshire
Problem with your window and door surrounds in Tillicoultry? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Cracked mastic round a front door frame
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ask a joiner to look at soft timber first
- Look over the window mastic once a year
- Make sure water runs off the sill
- Take care around the mastic when scraping paint
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
How we handle sand mastic in Tillicoultry
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have mastic round period door frames that has failed and tired mastic found when preparing windows for paint, we can help, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Tillicoultry depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

What sand mastic looks like in Tillicoultry
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In the older streets around Parish Church of St. Serf, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Alloa station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.

Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Common problems we fix in Tillicoultry
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they generally need raking out.
The problems people usually mention when they call are:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
- Open joints round the window box
- Patchy fillers round a sash window
For site and facilities teams at buildings such as Alva Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Tillicoultry, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
