Gilmerton homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes 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.
Around Gilmerton, as everywhere, sand mastic is only as good as the preparation behind it.

Sand mastic in Gilmerton, done properly
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead and we will explain which is best for yours. If you’re dealing with window mastic to renew ahead of painting and gaps round a timber door in stone or brick, we can help, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Gilmerton is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months, in Gilmerton and everywhere else we cover.

Why act early in Gilmerton
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In an older home around Gilmerton, damp from a failed joint can get into timber and plaster.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Gilmerton: your questions answered
Will you come out to Gilmerton?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Gilmerton?
Yes. Our work covers the whole of Scotland, and Gilmerton is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Do you guarantee sand mastic work?
You get our one-year guarantee on every job.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Aftercare tips
A little care helps the new joints last. We recommend:
- Take care around the mastic when scraping paint
- Clear gutters so water doesn’t pour onto the windows
- Plan mastic work ahead of painting
- Ask the planning authority about consent for listed or conservation-area homes
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

Different surfaces, different methods
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
