DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Sand mastic in Bridge of Cally, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on tenement windows, brick reveals and sash and case windows, and common reasons people get in touch are old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look.
In and around a place like Bridge of Cally, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Each job carries a 12-month guarantee, large or small.

How the job changes by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Bridge of Cally questions
Is Bridge of Cally within the area you cover?
Yes. Bridge of Cally is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on sand mastic in Bridge of Cally?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before we start.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

- Old sand mastic that has cracked, crumbled or fallen out
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
In and around Bridge of Cally, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What sand mastic looks like in Bridge of Cally
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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.
If you live in an older home near Netherton Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
