Sand mastic in Muchalls, done properly
Across Muchalls, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you’re dealing with weathered mastic on the most exposed windows and silicone on a period window that looks wrong, we can put it right, on brick reveals, stone surrounds and period & listed homes alike.
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.
Big or small, it’s backed by our one-year guarantee.

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. Somewhere like Muchalls may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.

FAQs for Muchalls
Do you cover smaller places like Muchalls?
Yes. Muchalls is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Portlethen station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Are you insured?
Yes. We’re fully insured for every job we do.
Is it worth trying it myself?
It depends on the job. 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.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Is the work guaranteed?
Every job comes with our 12-month guarantee, and we’re fully insured.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Common problems we fix in Muchalls
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
Common reasons people contact us are:
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
- Mastic dropping out of the joint
In the older streets around Saint Ternan's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Don’t paint over the new mastic
- Take care around the mastic when scraping paint
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Sashes that need overhauling
- Broken panes
- Timber that has rotted
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Timber door frames
- Tenement windows
- Brick reveals
- Stone surrounds
- Sash and case windows
- Period & listed homes
What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What sand mastic looks like in Muchalls
Muchalls is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Rented homes near Portlethen station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
