Sand mastic for homes and businesses in Whitehills
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We are often asked to deal with gaps round a timber door in stone or brick and mastic worn away on windows facing the weather, across tenement windows, sash and case windows and stone surrounds.
Outdoor sealant needs a dry surface, so window work around Whitehills is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Do you need sand mastic in Whitehills?
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber and we normally remove them.
These are the problems we’re asked about most:
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Old cement repairs round a window that have failed
- Mastic worn away on windows facing the weather
Managing a site like Duncanrig Secondary School? Then the mastic around its windows and doors needs looking after like any other building’s.

What sand mastic looks like in Whitehills
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Whitehills is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
For landlords with property near East Kilbride station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- When we can work, for business premises
- Whether the work is at height
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- What’s wrong with the joints now
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job.
DIY versus a professional finish
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, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Whitehills
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
