Advice
Sand mastic in Kelloholm
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you have draughts and rain around sash boxes and mastic worn away on windows facing the weather, we can help, on stone surrounds, tenement windows and brick reveals alike.
In and around a place like Kelloholm, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
You get a one-year guarantee, the same in Kelloholm as everywhere else we work.

DIY versus a professional finish
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.
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.
Windows and doors in Kelloholm
Sash and case windows are common in older Scottish homes, 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.
Around Kelloholm, as everywhere, sand mastic is only as good as the preparation behind it.

Common problems we fix in Kelloholm
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Keep an eye out for any of the following:
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
- Silicone on a period window that looks wrong
If you let a flat or house near Kirkconnel station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
What to look for in a quote
- Whether they’re fully insured
- When the joint can take water or movement
- The length of the guarantee
- Whether they seal over old material or remove it
Why deal with it now?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
