About sand mastic in East Renfrewshire
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. Common call-outs are for mastic dropping out of the joint and gaps where the frame meets the masonry, on tenement windows, brick reveals and period & listed homes.
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows from start to finish.
- 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.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Pricing in East Renfrewshire
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Frames and weather across East Renfrewshire
Homes across East Renfrewshire range from period properties with timber or sash windows to new builds with uPVC. Exposed walls are where window sealant usually fails first, wherever they are in East Renfrewshire.
Homes in Scotland come with their own details: sash and case windows, harled walls and, in the towns and cities, tenement flats. We work across Scotland, including East Renfrewshire.
Newton Mearns: If you let a flat or house near Patterton station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Mearns Castle High School, its window and door frames need their mastic kept sound, just like a home’s.
Why it fails
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
These are the problems we are asked about most:
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
- Modern sealant on a period surround
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them.
What your quote should include
- Are they insured?
- How long to leave it before use
- Whether all the old sealant comes out first
- Whether VAT is included
What affects the quote in East Renfrewshire
There’s no set price list, because no two jobs are the same. What we look at:
- Access and height
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Any working-time requirements on site
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Get any rot dealt with first
- Take care around the mastic when scraping paint
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
East Renfrewshire: your questions answered
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
