Window mastic for homes and businesses in Innis nan Lìon
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. Common call-outs are for gaps between the frame and the inside reveal and a bead that doesn’t match the frame, on timber windows & doors, aluminium frames and uPVC windows.
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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Quotes for window mastic in Innis nan Lìon
We quote each job individually. This is what makes a difference:
- How much there is to do
- How many areas need sealing
- Which sealant suits the joint
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Leave it or put it right?
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around Innis nan Lìon, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Innis nan Lìon questions
Is Innis nan Lìon in your area for window mastic?
Yes. We work across all of Scotland, and Innis nan Lìon is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
What guarantee comes with window mastic in Innis nan Lìon?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.

Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave.

- First, we confirm safe access to each frame.
- 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.
