How we handle window mastic in Partick
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you’re dealing with untidy mastic left by window fitters and water coming in at the bottom corners of a door, we can put it right.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you’re in a tenement flat or a house in Partick, the joint between frame and wall is what keeps the weather out.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Looking after it afterwards
After the cure time, these simple habits help:
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What else we do in Partick
How the job changes by surface
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that, where a rigid one would crack.
Honest limits
We won’t take on work that will not last, so these are the limits:
- A sash or casement that will not close properly
- Damp coming through the wall itself rather than the frame joint
- Worn gaskets, brush seals or a door that has dropped
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Composite doors
- Aluminium frames
- Patio & French doors
- uPVC windows
- Window sills
- Timber windows & doors
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Access and height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote

Common questions in Partick
Do you cover Partick for window mastic?
Yes, Partick 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.
Who arranges sealant work on the shared parts of a tenement in Partick?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
How long will my window job take?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Do you need window mastic in Partick?
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Most people get in touch when they notice one of these:
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
Tenement House, about 1.6 miles east, is one of the historic houses in the wider area around Partick, and older homes nearby need a sealant that suits their walls.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door. Inside a flat in Partick, 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.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit

What window mastic looks like in Partick
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. Partick 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.
Managing a site like St Peter's Boys School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Partick station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
