Sand mastic for homes and businesses in Partick
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, tenement windows and period & listed homes, and the jobs we see most are crumbling sand mastic round a window and patchy fillers round a sash window.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Partick, the joint between frame and wall is what keeps the weather out.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Do you cover Partick for sand mastic?

Do you work for landlords with property near Partick station?

Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll talk you through it.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Timber that has rotted
- Sashes that rattle, stick or will not open
- Masonry that needs repairing
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Joints and surfaces we work on
- Timber door frames
- Brick reveals

Aftercare tips
A little care helps the new joints last. Our advice:
- Avoid patching sand mastic with silicone
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Check with your local planning authority if your home is listed
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
Why act early in Partick
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a tenement flat in Partick, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Doing several joints on one visit is generally more efficient than separate visits. We’ll send you a clear quote for the lot.
Why Partick customers choose us
- Anti-fungal sanitary silicone in wet areas
- Quality sealants from Arbo and Everbuild
- Neat joints and a tidy finish
- Every job guaranteed for a year

Partick homes and the weather
Historic houses like Tenement House (about 1.6 miles east) are a reminder that the area around Partick has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Managing a site like St Peter's Boys School? Then larger buildings have plenty of frames, and the mastic around each one ages. Tenement House, about 1.6 miles east, is one of the historic houses in the wider area around Partick.

What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- The old material and how stubborn it is
- Any mould that needs treating
- How many areas need sealing
- Which sealant suits the joint
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Advice
Do you need sand mastic in Partick?
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Gaps between timber frames and stone or brick
For landlords with property near Partick station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
