Window mastic for homes and businesses in Comrie
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have hard, cracked sealant around windows and cold air getting in at the frame edge, we can help, on aluminium frames, uPVC windows and timber windows & doors alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Comrie depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Comrie homes and the weather
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Comrie, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Comrie
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that’s a job for a joiner.
Aftercare tips
Aftercare is simple:
- Do not aim a pressure washer at the joints
- Ventilate rooms so frames don’t stay wet inside
- Keep drainage slots and sill grooves clear
- Do not paint over the silicone
Silicone can’t generally be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What we’re called out for in Comrie
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Common reasons people contact us include:
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
- Mastic that is falling out in pieces
- Draughty joints inside around the window
For an older house near a landmark such as Secession Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
