About our sand mastic in Shieldhall
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Common call-outs are for patchy fillers round a sash window and a silicone bead on a sash window that spoils the look, on sash and case windows, timber door frames and tenement windows.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you’re in a tenement flat or a house in Shieldhall, the joint between frame and wall is what keeps the weather out.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Check with your local planning authority if your home is listed
- Don’t run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
- Do not paint over the new mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Shieldhall homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Historic houses such as Pollok House, about 3.3 miles south-east, show how far back building around Shieldhall goes, and older homes nearby need a sealant that suits their walls. Schools such as Renfrew High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need sand mastic in Shieldhall?
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
The problems people normally mention when they call are:
- Silicone on a period window that looks wrong
- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
- Weathered mastic on the most exposed windows
Rented homes near Hillington West station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Shieldhall questions
How is work on the outside of a tenement in Shieldhall usually arranged?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can you do sand mastic in Shieldhall?
Yes, Shieldhall is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
How long does sand mastic take to harden?
Not right away. The skin forms first, and the full set comes later, and we will tell you what to expect.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.
