How we handle sand mastic in Clayholes
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. If you’re dealing with old sand mastic that has cracked, crumbled or fallen out and patchy fillers round a sash window, we can put it right, on brick reveals, timber door frames and tenement windows alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Around Clayholes, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.

What the job involves on each surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Frames and glazing around Clayholes
Clayholes is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
Homes close to Carnoustie Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Carnoustie High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Clayholes is about 1 mile north-west of Carnoustie, in Angus. Homes, rented property, offices and hotels in Clayholes is covered for sand mastic. The work is guaranteed for a year. Clayholes is one of 40 towns and villages in Angus we cover. We also work in Dundee, about 10 miles from Clayholes.

What’s near Clayholes
The nearest railway station is Golf Street station, roughly 0.9 miles south. Nearby you will also find Ashludie Hospital (3.8 miles west) and Panmure Castle (1.4 miles north).
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Have rotten timber repaired before new mastic goes in
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
- Go gently near the mastic when preparing windows
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Common questions in Clayholes
Is Clayholes within the area you cover?
Yes. Clayholes is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Clayholes affect outside sealant?
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. Walls facing the sea are usually the first to need attention.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can old silicone round a sash window be swapped for sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Do you need sand mastic in Clayholes?
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Look out for any of the following:
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
Rented homes near Golf Street station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
