Sand mastic for sash & case windows in Tannadice, Angus
We cover Tannadice for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Mastic worn away on windows facing the weather
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
How we handle sand mastic in Tannadice
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, sash and case windows and tenement windows, and the jobs we see most are mastic round period door frames that has failed and window mastic to renew ahead of painting.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look over the window mastic once a year
- Do not paint over the new mastic
- Take care around the mastic when scraping paint
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The type of sealant required
- The old material and how stubborn it is
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we’ll talk you through it.
What to tell us for a quote
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- Roughly how big the job is
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours per window, depending on the condition of the joints. Outside jobs in Tannadice need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

We also work for property managers and facilities teams in Tannadice and across Angus. We can quote a run of properties together, and we’re fully insured.
If you manage several properties in or around Tannadice, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
When something else is needed

- Cracked or broken glass
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes

Period and listed homes
Period homes look their best with traditional materials.
Frames and glazing around Tannadice
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
In and around Tannadice, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. If you live in an older home near Parish Church And Old Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
