Sand Mastic in Greenfoot

Sand mastic for homes and businesses in Greenfoot
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on tenement windows, period & listed homes and stone surrounds, and the jobs we see most are weathered mastic on the most exposed windows and modern sealant on a period surround.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You get a 12-month guarantee, the same in Greenfoot as everywhere else we work.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

How do I get a quote for sand mastic in Greenfoot?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Greenfoot.
Signs you need sand mastic in Greenfoot
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they generally need raking out.
Look out for these signs:
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
In the older streets around Church Of Scotland, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before booking anyone
- What guarantee comes with the work
- Whether all the old sealant comes out first
- How much experience the applicator has
- What the cure time is
What happens on the day
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Greenfoot need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear the area around the work
- Mention if the joints have been sealed before

What sand mastic looks like in Greenfoot
Greenfoot is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Gartcosh 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 Buchanan High School, its window and door frames need their mastic kept sound, just like a home’s.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Make sure water runs off the sill
- Get any rot dealt with first
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
