Sand mastic in Halfway: local notes
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that will not mark it. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Schools such as Craigton Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Pollok House, about 1.3 miles south-east, is one of the historic houses in the wider area around Halfway, and older homes nearby need a sealant that suits their walls.
Halfway is about 2 miles south-west of Yorkhill, in Glasgow. Halfway gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Halfway is one of 183 places in Glasgow we cover for sand mastic.

About our sand mastic in Halfway
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We are often asked to deal with gaps between timber frames and stone or brick and window mastic to renew ahead of painting, across brick reveals, sash and case windows and stone surrounds.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. For a flat in Halfway, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
Each job carries a 12-month guarantee, whatever its size.

Common questions in Halfway
How is work on the outside of a tenement in Halfway generally arranged?
It normally 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.
Is Halfway in your area for sand mastic?
Yes, Halfway is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
How long does sand mastic take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we’ll say how long yours will take.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
How do I get a quote for sand mastic in Halfway?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
The process
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Halfway, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

- The product the joint needs
- Whether the work is at height
- The number of rooms or windows
- The old material and how stubborn it is
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- The rough size of the job
- Whether it has been sealed before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Decisions on consent for listed homes
- Decayed frames that need repair
- Broken panes
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Look over the window mastic once a year
- Clear gutters so water doesn’t pour onto the windows
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
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 we’re called out for in Halfway
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Keep an eye out for these signs:
- Mastic worn away on windows facing the weather
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
If you let a flat or house near Corkerhill station, older sash windows in a rental need their mastic kept sound to keep the weather out.
