How we handle window mastic in Inchmagrannachan
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We’re often asked to deal with whistling draughts around closed windows and cracked or shrunken mastic around the frame, across window sills, aluminium frames and timber windows & doors.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You’re covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What we’re called out for in Inchmagrannachan
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The problems people usually mention when they call include:
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
In and around Inchmagrannachan, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

- The length of the guarantee
- What happens if they find a problem under the old sealant
- Is VAT in the price?
What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. 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.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before any work starts.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Frames and glazing around Inchmagrannachan
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Dunkeld & Birnam station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure the drainage slots aren’t blocked
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
- Keep timber frames painted
Most silicone sealants will not take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
