Window Mastic in Stoer
Problem with your window and door frames in Stoer? We cut out the old, prepare the joints and apply the right sealant.
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
How we handle window mastic in Stoer
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you are dealing with untidy mastic left by window fitters and cracked sealant at the sill ends, we can help, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, large or small.

What the job involves on each surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
When to call us in Stoer
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us include:
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
Whether the job is in Stoer itself or nearby, the right material for each joint matters as much as a neat finish.

Window mastic in Stoer: local notes
Stoer is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Stoer, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Questions from Stoer
Can you do window mastic in Stoer?
Yes, Stoer is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Does living near the coast affect window mastic in Stoer?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.

DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Keeping the joints in good condition
So the new joints stay in good condition:
- Avoid harsh chemicals near the mastic
- Do not paint over the silicone
- Repaint timber before it’s bare
- Keep jet washers away from the mastic
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. For a place like Stoer, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
