Newbank Window Mastic
Window and door frames in Newbank need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
Window mastic in Newbank, done properly
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you are dealing with black, perished sealant on frames and sealant in the wrong colour for the frame, we can help, on aluminium frames, patio & French doors and uPVC windows alike.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. In Newbank, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
What we’re called out for in Newbank
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
People normally contact us when they notice one of these:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- Cracked or shrunken mastic around the frame
Historic houses such as Provand's Lordship, about 1.7 miles north-west, show how far back building around Newbank goes, and older homes nearby need a sealant that suits their walls.

FAQs for Newbank
How do repairs to the shared parts of a tenement in Newbank 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. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you do window mastic in Newbank?
Yes. We work across all of Scotland, and Newbank is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. For a tenement in Newbank, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

What else we do in Newbank
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Wind-driven rain gets into any failed joint on the outside of a city building, and in Newbank, damp can spread through stone and plaster before anyone sees it.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Walk round the house once a year and look at the joints
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Window mastic in Newbank: local notes
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. Glasgow’s tenements are largely red and blond sandstone, and porous sandstone needs a sealant that won’t mark it.
For landlords with property near Duke Street station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as St Mungo's Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
