Sand mastic for sash & case windows in Linthouse, Glasgow
Window and door surrounds in Linthouse need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
How we handle sand mastic in Linthouse
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include patchy fillers round a sash window and gaps between timber frames and stone or brick, on brick reveals, tenement windows and timber door frames.
Linthouse is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Your job is guaranteed for a year, as with all our work.

Frames and glazing around Linthouse
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows normally belong to the flat, but the title deeds have the final say. Historic houses like Tenement House (about 2.4 miles east) are a reminder that the area around Linthouse has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Linthouse Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Govan High School? Then the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Leave the new mastic unpainted
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Go gently near the mastic when preparing windows
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Signs you need sand mastic in Linthouse
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The most common problems we see are:
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- A silicone bead on a sash window that spoils the look
If you let a flat or house near Cardonald station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Crumbling stone or brickwork round the window
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)

Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Linthouse, it helps to know the floor, the door entry arrangements and the nearest parking.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
