Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Questions from Crookston
Can you do window mastic in Crookston?
Yes, Crookston 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, and we will send you a clear quote.
How do repairs to the shared parts of a tenement in Crookston get organised?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before work begins.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Where do you work from?
We work from Crawley. We cover Crookston and the rest of Glasgow.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Walk round the house once a year and look at the joints
- Don’t use solvent cleaners on the joint
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Common problems we fix in Crookston
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
People normally contact us after spotting something like this:
- Hard, cracked sealant around windows
- Mastic that is falling out in pieces
- Untidy mastic left by window fitters
- Water coming in at the bottom corners of a door
Managing a site like Rosshall Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

How it works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes a morning for a couple of windows and a door. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Crookston, tell us the floor, how the door entry system works and where we can park nearby.
- 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.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

What window mastic looks like in Crookston
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, and many buildings use a factor to arrange it. Windows normally belong to the flat, but the title deeds have the final say. Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
Letting a property close to Crookston station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Historic houses such as Pollok House, about 2.2 miles south-east, show how far back building around Crookston goes.

Local landmarks in Crookston
In Crookston, that means homes and buildings near Barshaw Park. Crookston has its own railway station: Crookston station. Nearby you will also find Leverndale Hospital (0.6 miles south) and Silverburn Shopping Centre (1.8 miles south-east).
What happens if it’s left?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
