Window mastic for homes and businesses in Bardowie
Homes in Bardowie have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include whistling draughts around closed windows and gaps between the frame and the inside reveal, across composite doors, window sills and uPVC windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Our work is backed for twelve months.

What window mastic looks like in Bardowie
With historic houses such as Tenement House (about 4.5 miles south) nearby, there’s older building stock in the area around Bardowie as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Schools such as Boclair Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Milngavie station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Do you need window mastic in Bardowie?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
People usually contact us after spotting something like this:
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Water coming in at the bottom corners of a door
Historic houses such as Tenement House, about 4.5 miles south, show how far back building around Bardowie goes, and older homes nearby need a sealant that suits their walls.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Honest limits
We will always be straight with you, so here’s what new sealant will not do:
- A sash or casement that will not close properly
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Patio & French doors
- Aluminium frames
- uPVC windows
