About our sand mastic in Kilmichael Glassary
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include mastic dropping out of the joint and failed mastic on an exposed elevation, across tenement windows, brick reveals and timber door frames.
Mastic can only go onto a dry joint, so outside work in Kilmichael Glassary depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
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.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It generally takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Kilmichael Glassary need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Advice
Your questions about sand mastic in Kilmichael Glassary
Is sand mastic in Kilmichael Glassary guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will you come out to Kilmichael Glassary?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are you fully insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we’ll explain why.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Windows and doors in Kilmichael Glassary
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
For an older house near a landmark such as Kilmichael Glassary Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a place like Kilmichael Glassary, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
