Related advice
Sand mastic in Auchinstarry, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. If you have wind and rain getting in round a sash window and crumbling sand mastic round a window, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we’ll tell you how long to expect.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Auchinstarry homes and the weather
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. Auchinstarry 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.
Rented homes near Croy station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Our Lady's High, larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Whether work needs listed building consent
- Putty and glazing repairs
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.
What we seal
- Sash and case windows
- Period & listed homes
- Tenement windows
- Stone surrounds
- Brick reveals
- Timber door frames
Surface by surface
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- When we can work, for business premises
- The old material and how stubborn it is
- How easy the joints are to reach
- Any mould that needs treating
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Helping us quote
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
- The rough size of the job
- Where the job is, and your postcode
We quote each job on its own, so start by telling us what you need. Just send an email to info@mrmastic.co.uk with the details and send pictures if you have them.

Why it’s worth doing now in Auchinstarry
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.
