Stobswell Window Mastic
Window mastic across Stobswell and nearby, with old sealant always removed completely and a one-year guarantee.
- A bead that doesn’t match the frame
- Gaps where the sill meets the wall
- Mastic that is falling out in pieces
Window mastic in Stobswell, done properly
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on composite doors, window sills and aluminium frames, and the jobs we see most are gaps where the sill meets the wall and rushed sealant from a window installation.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Stobswell, and in a tenement the outside of the building may be a shared repair.
There’s a 12-month guarantee on every job, whatever its size.

What window mastic looks like in Stobswell
Stobswell is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Who owns the windows depends on the title deeds.
Rented homes near Dundee station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Morgan Academy, larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Do you need window mastic in Stobswell?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
People usually contact us when they notice something like this:
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- A bead that doesn’t match the frame
- Rain getting in at the frame or under the sill
If you live in an older home near St Patrick's R.C. Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common questions in Stobswell
I let a flat near Dundee station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Stobswell?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Are you fully insured?
Yes. We are fully insured.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Can new window sealant be painted?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you quote for more than one area?
Yes. Just list everything you need.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Keep drainage slots and sill grooves clear
- Use gentle cleaners on frames and sealant
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
