Window Mastic in Canisbay
Our applicators work in Canisbay on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Mastic that has split away from the wall
Common problems we fix in Canisbay
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
These are the problems we’re asked about most:
- Gaps where the sill meets the wall
- Gaps left after new windows were fitted
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
Homes close to Canisbay Parish Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Before you book anyone
- Whether they seal over old material or remove it
- What product goes in the joint
- How long the guarantee is
- Is VAT in the price?
Window mastic in Canisbay
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Common call-outs are for untidy mastic left by window fitters and white mastic on grey or black frames, across window sills, timber windows & doors and composite doors.
Outdoor sealant needs a dry surface, so window work around Canisbay is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Big or small, it’s backed by our 12-month guarantee in Canisbay and across Highland.

Advice
Questions from Canisbay
Does living near the coast affect window mastic in Canisbay?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover Canisbay for window mastic?
Yes. Our work covers the whole of Scotland, and Canisbay is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Windows and doors in Canisbay
Canisbay is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Around Canisbay, as everywhere, window mastic is only as good as the preparation behind it.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Landlords, agents and businesses in Canisbay
If you manage several properties in or around Canisbay, several properties can be quoted together. Send us the addresses and the work at each.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Keep timber frames painted
- Walk round the house once a year and look at the joints
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
