How we handle sand mastic in Lambhill
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you have gaps round a timber door in stone or brick and a silicone bead on a sash window that spoils the look, we can put it right, whatever the surface.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. In Lambhill, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
Big or small, it’s backed by our 12-month guarantee.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
Common problems we fix in Lambhill
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
The most common problems we see are:
- Window mastic to renew ahead of painting
- Silicone on a period window that looks wrong
- Mastic round period door frames that has failed
- Patchy fillers round a sash window
Rented homes near Possilpark & Parkhouse station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

FAQs for Lambhill
How is work on the outside of a tenement in Lambhill generally arranged?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Can you do sand mastic in Lambhill?
Yes, Lambhill is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How do I get a quote for sand mastic in Lambhill?
Every job is different, so each one gets its own quote. To get one, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Can old silicone round a sash window be swapped for sand mastic?
Normally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Sand mastic in Lambhill: local notes
Historic houses like Tenement House (about 1.7 miles south) are a reminder that the area around Lambhill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Schools such as John Paul Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Tenement House, about 1.7 miles south, is one of the historic houses in the wider area around Lambhill, and older homes nearby need a sealant that suits their walls.

Landlords, agents and businesses in Lambhill
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Private landlords in Lambhill must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.
