How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

Advice
About our sand mastic in Cunningsburgh
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, stone surrounds and brick reveals, and the jobs we see most are draughts and rain around sash boxes and cracked mastic round a front door frame.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Each job carries a 12-month guarantee, large or small.

Common problems we fix in Cunningsburgh
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Mastic round period door frames that has failed
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Open joints round the window box
In and around Cunningsburgh, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What happens if it’s left?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a place like Cunningsburgh, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Cunningsburgh homes and the weather
Cunningsburgh is within about 1 mile 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so the more notice, the better.
Whether the job is in Cunningsburgh itself or nearby, the right material for each joint matters as much as a neat finish.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Common questions in Cunningsburgh

How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will advise.
How to look after the new joints
After the cure time, these simple habits help:
- Clear gutters so water doesn’t pour onto the windows
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
