Window mastic in Old Blair, done properly
Around Old Blair we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for cracked sealant at the sill ends and rushed sealant from a window installation, on window sills, patio & French doors and timber windows & doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Our work is backed for twelve months, in Old Blair and everywhere else we cover.

Your questions about window mastic in Old Blair
Is Old Blair within the area you cover?
Yes. Old Blair is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is Old Blair in your area for window mastic?
Yes. We work across all of Scotland, and Old Blair is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is the new sealant paintable?
Not usually, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How many windows can you do in a day?
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.
Why it’s worth doing now in Old Blair
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In an older home around Old Blair, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Mention tracks, gates, ferries or anything else about the route.
- We start by checking each window and door with you.

Do you need window mastic in Old Blair?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
If you can see any of these, it’s time to have the joints looked at:
- Untidy mastic left by window fitters
- Mastic that is falling out in pieces
- Cracked internal joints between frame and plaster
- Damp patches on the reveal after heavy rain
If you let a flat or house near Blair Atholl station, renewing tired window mastic between tenants heads off draught and damp complaints.
Before you book anyone
- Whether they’re fully insured
- Whether VAT is included
- How much experience the applicator has
- Which sealant they’ll use, and why
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
- Keep paint off silicone joints
- Wipe condensation off the frames
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Window mastic in Old Blair: local notes
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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Old Blair, as everywhere, window mastic is only as good as the preparation behind it.

Surface by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
