About our window mastic in Sandyhills
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have draughty joints inside around the window and mastic that has split away from the wall, we can put it right, on timber windows & doors, uPVC windows and window sills alike.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What we cannot put right

- Penetrating damp from a failed cavity tray or render
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)

Common problems we fix in Sandyhills
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The most common problems we see are:
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
- White mastic on grey or black frames
- Rain getting in at the frame or under the sill
Rented homes near Shettleston station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sandyhills questions
I let a flat near Shettleston station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
How do repairs to the shared parts of a tenement in Sandyhills get organised?
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 don’t.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
How do I get a quote for window mastic in Sandyhills?
Size, access and the old material all affect the cost. Ask us for a quote.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Can I paint over the new sealant?
Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Surface by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Sandyhills homes and the weather
Historic houses like Provand's Lordship (about 3.5 miles west) are a reminder that the area around Sandyhills has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Provand's Lordship, about 3.5 miles west, is one of the historic houses in the wider area around Sandyhills, and older homes nearby need a sealant that suits their walls. Managing a site like Eastbank Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Sandyhills
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Private landlords in Sandyhills must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
