I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can I paint the new mastic?

Sand mastic for homes and businesses in Dinnet
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we will advise if you’re redecorating. We are often asked to deal with crumbling sand mastic round a window and mastic worn away on windows facing the weather, on sash and case windows, stone surrounds and period & listed homes.
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.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Dinnet, water from a failed joint in an older stone home can soak into timber and plaster.
Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.
What you get with us

Quotes for sand mastic in Dinnet
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Working hours on commercial sites
- How many areas need sealing
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Whether it has been sealed before
- The type of property
- A few pictures by email, if you can
- What’s wrong with the joints now
To get a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. We’ll give you a clear price before any work starts.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Decayed frames that need repair
- Whether work needs listed building consent
- Broken panes
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.

Dinnet homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Homes close to Dinnet Parish Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Signs you need sand mastic in Dinnet
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
It’s worth asking for a quote if you see:
- Window mastic to renew ahead of painting
- Silicone on a period window that looks wrong
- Mastic dropping out of the joint
- Failed mastic on an exposed elevation
In and around Dinnet, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
