How we handle sand mastic in Kincardine O'Neil
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. If you’re dealing with old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, we can put it right, on sash and case windows, stone surrounds and period & listed homes alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Big or small, you get the same one-year guarantee in Kincardine O'Neil and across Aberdeenshire.

- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.

Related advice
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.

Landlord and commercial work in Kincardine O'Neil
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Why act early in Kincardine O'Neil
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Kincardine O'Neil homes and the weather
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Whether the job is in Kincardine O'Neil itself or nearby, the right material for each joint matters as much as a neat finish. Around Kincardine O'Neil, as everywhere, sand mastic is only as good as the preparation behind it.

Aftercare tips
Looking after new joints is easy:
- Clear gutters so water does not pour onto the windows
- Sort the mastic before the decorators arrive
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
When something else is needed
A few problems are outside what sealant work can do:
- Whether work needs listed building consent
- Sashes that need overhauling
- Timber that has rotted
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
