Window & door mastic in Yoker, Glasgow
Our applicators work in Yoker on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Leaking joints at the ends of sills
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes most of a day for a typical house, less for a few frames. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Yoker, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- 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.
How to prepare
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Window mastic in Yoker
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on patio & French doors, timber windows & doors and aluminium frames, and people most often call us about draughts coming in around windows and doors and mastic that has split away from the wall.
Yoker is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
We stand behind the work with a 12-month guarantee.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What affects the quote in Yoker
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- Working hours on commercial sites
- The number of rooms or windows
- The type of sealant required
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. We take all of that into account in your quote.
What to tell us for a quote
When you call or email, these details help:
- Pictures of the joints, sent by email

Why it’s worth doing now in Yoker
The work is quick compared with the damage it prevents: it takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Yoker, damp can travel a long way before it shows.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Common problems we fix in Yoker
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Keep an eye out for any of the following:
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Draughty joints inside around the window
If you look after a building such as Saint Andrew's High School, its window and door frames need their mastic kept sound, just like a home’s.

Yoker homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Yoker is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
For landlords with property near Yoker station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Hamilton Memorial Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
