Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Window mastic in Townhead
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We are often asked to deal with gaps left after new windows were fitted and cracked internal joints between frame and plaster, on aluminium frames, uPVC windows and composite doors.
Townhead is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
We stand behind the work with a one-year guarantee.

Common problems we fix in Townhead
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.
If you can see any of these, it’s time to have the joints looked at:
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
Provand's Lordship, about 0.4 miles south-east, is one of the historic houses in the wider area around Townhead.

Townhead questions
Do you cover Townhead for window mastic?
Yes, Townhead is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you help a landlord with a rental near Glasgow Queen Street station?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Is the new sealant paintable?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Window mastic in Townhead: 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Managing a site like Allan Glen's School? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Glasgow Queen Street station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure the drainage slots aren’t blocked
- Check the mastic once a year
- Do not aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
When it is not the sealant
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Timber windows & doors
- Composite doors
- Aluminium frames
- Window sills
- Patio & French doors

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Townhead, it helps to know the floor, the door entry arrangements and the nearest parking.
- 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.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
