Window mastic in Royston, done properly
From a single sill to a whole house of windows, the work is priced before anything is done. Just send an email to info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. We work on patio & French doors, aluminium frames and window sills, and common reasons people get in touch are draughts coming in around windows and doors and gaps left after new windows were fitted.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Royston, the joint between frame and wall is what keeps the weather out.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes most of a day for a typical house, less for a few frames. In a city area like Royston, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- Each frame is looked over and we agree which ones need resealing.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

What else we do in Royston
Do you need window mastic in Royston?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Keep an eye out for these signs:
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
- Mastic that is falling out in pieces
Rented homes near Barnhill station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Why act early in Royston
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. 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.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Why us?
- Anti-fungal sanitary silicone in wet areas
- Fully insured
- An ARBOMaster approved applicator
- We leave the area clean and tidy

Frames and glazing around Royston
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. With historic houses such as Provand's Lordship (about 0.5 miles south) nearby, there’s older building stock in the area around Royston as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Townhead and Blochairn Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as St. Roch's Secondary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

For landlords and businesses
We also work for property managers and facilities teams in Royston and across Glasgow. We can quote a run of properties together, and we’re fully insured for the work.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Aftercare tips
After the cure time, these simple habits help:
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Don’t aim a pressure washer at the joints
- Air rooms to keep condensation down around windows
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
