About our window mastic in Shawfair
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Typical jobs include white mastic on grey or black frames and old mastic that has gone black or come away, on composite doors, aluminium frames and timber windows & doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- A frame that has rotted at the joint
- Faulty window hardware
- Condensation trapped between the panes

Aftercare tips
Good habits help new joints last longer. A few tips:
- Walk round the house once a year and look at the joints
- Clean frames with a soft cloth and soapy water
- Keep jet washers away from the mastic
- Avoid harsh chemicals near the mastic
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

Expect the work to take a morning for a couple of windows and a door, and we tell you how long to leave it before we go.

Shawfair homes and the weather
Shawfair is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Newton Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Castlebrae Community High School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Shawfair station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why act early in Shawfair
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Shawfair, water from a failed joint in an older stone home can soak into timber and plaster.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
