Windows and doors in Kinlochleven
Kinlochleven 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. 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.
In and around Kinlochleven, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How we handle window mastic in Kinlochleven
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Common call-outs are for rushed sealant from a window installation and damp patches on the reveal after heavy rain, on patio & French doors, composite doors and timber windows & doors.
Mastic can only go onto a dry joint, so outside work in Kinlochleven depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Every job comes with our 12-month guarantee, wherever you are in Highland.

What else we do in Kinlochleven
What the job involves on each surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes most of a day for a typical house, less for a few frames from start to finish. For a place like Kinlochleven, 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.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit

Related advice
Signs you need window mastic in Kinlochleven
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.
People usually contact us when they notice one of these:
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
Whether the job is in Kinlochleven itself or nearby, the right material for each joint matters as much as a neat finish.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.

FAQs for Kinlochleven
Does the coastal weather in Kinlochleven affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Kinlochleven within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do upstairs windows?
Yes, in most cases. Access is planned before work begins.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Are you fully insured?
Yes, we are fully insured.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
How to look after the new joints
Aftercare is simple:
- Keep paint and stain on wooden frames in good order
- Look round the frames every year or so
- Paint up to the joint, not over it
- Do not use solvent cleaners on the joint
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Why act early in Kinlochleven
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
