About our sand mastic in Laurencekirk
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we will explain which is best for yours. We work on period & listed homes, sash and case windows and timber door frames, and common reasons people get in touch are mastic worn away on windows facing the weather and old cement repairs round a window that have failed.
Mastic can only go onto a dry joint, so outside work in Laurencekirk depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All our work is covered by our 12-month guarantee.

Why it’s worth doing now in Laurencekirk
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- More than 20 years in sealant work

Frames and glazing around Laurencekirk
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Common problems we fix in Laurencekirk
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Common reasons people contact us include:
- Gaps where the frame meets the masonry
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
For an older house near a landmark such as Laurencekirk, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Whether all the old sealant comes out first
- What preparation is included

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Different surfaces, different methods
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
