About our window mastic in Corpach
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on window sills, uPVC windows and timber windows & doors, and common reasons people get in touch are cold air getting in at the frame edge and mastic that has split away from the wall.
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.
Whatever the size of the job, you get the same one-year guarantee in Corpach and across Highland.

Frames and glazing around Corpach
Corpach is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
If you look after a building such as Lochaber High School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Corpach station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render

Corpach: your questions answered
Can you help a landlord with a rental near Corpach station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Corpach?
Yes. Corpach is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can I paint over the new sealant?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
How much does window mastic cost in Corpach?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Why act early in Corpach
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In an older home around Corpach, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Around Corpach, distance and access matter more than parking.

- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Walk round the house once a year and look at the joints
- Do not aim a pressure washer at the joints
- Keep paint off silicone joints
- Air rooms to keep condensation down around windows
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
