How we handle sand mastic in Duncrievie
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with open joints round the window box and cracked mastic round a front door frame, we can put it right.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
You’re covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. Around Duncrievie, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Clear the area around the work

Related advice
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
Avoid painting over the new mastic, which is the traditional advice. If you’re redecorating, ask us first.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.

Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Can you do several jobs on one visit?

Is the work guaranteed?

Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Why it’s worth doing now in Duncrievie
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Around Duncrievie, water from a failed joint in an older stone home can soak into timber and plaster.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Frames and glazing around Duncrievie
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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In and around Duncrievie, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. For an older house near a landmark such as Arngask Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
