Window & door mastic in Anniesland, Glasgow
Our applicators work in Anniesland 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.
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- White mastic on grey or black frames
About our window mastic in Anniesland
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you’re dealing with rushed sealant from a window installation and black, perished sealant on frames, we can put it right, whatever the surface.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Anniesland, and in a tenement the outside of the building may be a shared repair.
All our work comes with a 12-month guarantee.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
When to call us in Anniesland
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
If you can see any of these, it’s time to have the joints looked at:
- Black, perished sealant on frames
- White mastic on grey or black frames
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
For site and facilities teams at buildings such as Knightswood Secondary School, its window and door frames need their mastic kept sound, just like a home’s.

Windows and doors in Anniesland
Anniesland 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. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Windows normally belong to the flat, but the title deeds have the final say.
If you live in an older home near Jordanhill Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Anniesland station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Inside a flat in Anniesland, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp problems in the wall away from the window
- A sash or casement that will not close properly
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
What we seal

- Timber windows & doors
- uPVC windows
- Patio & French doors

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Do not aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
- Wash the frames with mild soapy water
- Look round the frames every year or so
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Your questions about window mastic in Anniesland
Is Anniesland in your area for window mastic?
Yes, Anniesland is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
How do repairs to the shared parts of a tenement in Anniesland get organised?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can new window sealant be painted?
Most silicone can’t be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Why act early in Anniesland
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. For landlords in Anniesland, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

- Sanitary silicone with an anti-fungal additive in wet areas
