Sand mastic in Mastrick, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. If you have patchy fillers round a sash window and window mastic to renew ahead of painting, 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 Mastrick, and in a tenement the outside of the building may be a shared repair.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What sand mastic looks like in Mastrick
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Historic houses such as Friendville, about 1.9 miles south-east, show how far back building around Mastrick goes, and older homes nearby need a sealant that suits their walls. Letting a property close to Aberdeen station? Then any sash windows need sound mastic to keep draughts and rain out. Schools such as Northfield Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Plan mastic work ahead of painting
- Avoid heavy scraping on the mastic joint
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. Parking in city streets around Mastrick can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- 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

Advice
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Wind-driven rain gets into any failed joint on the outside of a city building, and in Mastrick, damp can spread through stone and plaster before anyone sees it.

Quotes for sand mastic in Mastrick
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- The type of sealant required
- The old material and how stubborn it is
- Access and height
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
When you contact us, it’s useful to know:
