- Old mastic that has gone black or come away
How we handle window mastic in Daldowie
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with hard, cracked sealant around windows and cracked internal joints between frame and plaster, we can put it right, on composite doors, aluminium frames and patio & French doors alike.
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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Worn gaskets, brush seals or a door that has dropped
- A sash or casement that won’t close properly
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Window sills
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Composite doors
Surface by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.

Landlord and commercial work in Daldowie
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a morning for a couple of windows and a door. Outside jobs in Daldowie need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts

Do you need window mastic in Daldowie?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Signs it’s time to call us include:
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
If you look after a building such as Uddingston Grammar School, the mastic around its windows and doors needs looking after like any other building’s.

- Who turns up on the day
- What happens if they find a problem under the old sealant

Frames and glazing around Daldowie
The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you let a flat or house near Baillieston station, renewing tired window mastic between tenants heads off draught and damp complaints.

Daldowie questions
I let a flat near Baillieston station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you do window mastic in Daldowie?
Yes. We work across all of Scotland, and Daldowie is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can you match the sealant to my frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. You’ll get a timescale with the quote.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
