How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job normally takes a few hours for a handful of frames, longer for a whole house. Outdoor work around Clachan Shannda depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.

How we handle window mastic in Clachan Shannda
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have sealant in the wrong colour for the frame and gaps between the frame and the inside reveal, we can help.
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’ll put it right.

What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- Working hours on commercial sites
- Whether there’s mould to deal with
- How easy the joints are to reach
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What’s wrong with the joints now

- Any previous sealing or DIY work
Every job is quoted individually. Simply email us at info@mrmastic.co.uk and describe the job, and photos are welcome.
When to call us in Clachan Shannda
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
The problems people normally mention when they call are:
- Cracked sealant at the sill ends
- Mastic that’s falling out in pieces
- Gaps between the frame and the inside reveal
- Sealant in the wrong colour for the frame
Whether the job is in Clachan Shannda itself or nearby, the right material for each joint matters as much as a neat finish.

Clachan Shannda homes and the weather
Clachan Shannda 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
In and around Clachan Shannda, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

FAQs for Clachan Shannda
Is Clachan Shannda in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Clachan Shannda is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Does living near the coast affect window mastic in Clachan Shannda?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we will tell you.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before we start.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Honest limits
In fairness, there are a few things sealant will not fix:
- Rotten timber, which needs a joiner first
- Damp problems in the wall away from the window
- A sash or casement that will not close properly
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Patio & French doors
- Timber windows & doors
- Window sills
- Aluminium frames
- Composite doors
- uPVC windows
Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
