Window & door mastic in Glen More, Highland
Mastic around window and door frames, sills and patio doors in Glen More, with a 12-month guarantee on every job. Call for a quick quote.
- Mastic that is falling out in pieces
- Gaps between the frame and the inside reveal
- A bead that does not match the frame
How the job changes by surface
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Window mastic in Glen More, done properly
Homes in Glen More have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We are often asked to deal with gaps left after new windows were fitted and cracked or shrunken mastic around the frame, across uPVC windows, window sills and patio & French doors.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What else we do in Glen More
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Composite doors
- uPVC windows
- Patio & French doors
- Aluminium frames
- Timber windows & doors
- Window sills
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Clear any debris from frame drain holes
- Do not aim a pressure washer at the joints
- Keep timber frames painted
- Don’t use solvent cleaners on the joint
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Common problems we fix in Glen More
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
People normally contact us after spotting something like this:
- Gaps left after new windows were fitted
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Black, perished sealant on frames
For jobs in and around Glen More, choosing the right material for each joint is as important as a tidy finish.

What happens on the day
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go. Around Glen More, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit

Your questions about window mastic in Glen More
Do you cover Glen More for window mastic?
Yes. Our work covers the whole of Scotland, and Glen More is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Is window mastic in a coastal place like Glen More any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Glen More.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Window mastic in Glen More: local notes
Glen More is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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 sound outside sealant is part of that.
In and around Glen More, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
