Sand mastic for sash & case windows in Glenrothes, Fife
Window and door surrounds in Glenrothes need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
- Wind and rain getting in round a sash window
How to look after the new joints
So the new joints stay in good condition:
- Keep sills and gutters clear so water drains away
- Renew mastic before redecorating the windows
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
How we handle sand mastic in Glenrothes
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. We work on stone surrounds, tenement windows and period & listed homes, and common reasons people get in touch are old cement repairs round a window that have failed and gaps between timber frames and stone or brick.
Harled walls are common in Scottish towns like Glenrothes, and sealing a frame against rough harling takes a sealant that grips and moves. A bead that sits on top of the harling rather than in the joint soon lets water in.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.
Leave it or put it right?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. For landlords in Glenrothes, damp and leaks can fall under the Repairing Standard. Sorting failed joints early is easier than dealing with a tenant’s complaint.

What the job involves on each surface
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
What we’re called out for in Glenrothes
Timber frames move with the seasons. The movement cracks the mastic over time.
These are the problems we’re asked about most:
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
- A silicone bead on a sash window that spoils the look
For landlords with property near Markinch station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What sand mastic looks like in Glenrothes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In the older streets around St Columba's Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Auchmuty High School, larger buildings have plenty of frames, and the mastic around each one ages.
