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 just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Sand mastic in Greenfield
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. If you have mastic dropping out of the joint and gaps where the frame meets the masonry, we can help.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Greenfield, and in a tenement the outside of the building may be a shared repair.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

- Mastic dropping out of the joint
- Mastic round period door frames that has failed
- Open joints round the window box

For site and facilities teams at buildings such as Eastbank Academy, the mastic around its windows and doors needs looking after like any other building’s.

Sand mastic in Greenfield: local notes
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. 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.
If you let a flat or house near Shettleston station, older sash windows in a rental need their mastic kept sound to keep the weather out. Provand's Lordship, about 2.7 miles west, is one of the historic houses in the wider area around Greenfield.

Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will advise.
Is the work guaranteed?
Every job comes with our 12-month guarantee.
Looking after it afterwards
To keep the joints looking good and working properly:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
- Check with your local planning authority if your home is listed
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Greenfield, damp can travel a long way before it shows.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Greenfield, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit

- Tell us about any previous sealing or DIY attempts
