Sand mastic in Ayr
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, brick reveals and tenement windows, and people most often call us about weathered mastic on the most exposed windows and mastic round period door frames that has failed.
Scottish towns like Ayr tend to mix older stone-built streets, harled houses and newer estates, and windows range from older sash and case to modern uPVC. Each needs the right sealant against the right wall.
Every job is covered by our 12-month guarantee, wherever you are in South Ayrshire.

Landlord and commercial work in Ayr
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Landlords and agents in Ayr can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
- Clear gutters so water doesn’t pour onto the windows
- Ask a joiner to look at soft timber first
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Parking around Ayr is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- 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.
How to prepare
- Mention any tricky access
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before

Advice
Common questions in Ayr
Can you do sand mastic in Ayr?
Yes, Ayr is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Is sand mastic in a coastal place like Ayr any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Should I use sand mastic or silicone?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.

Signs you need sand mastic in Ayr
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Old sand mastic that has cracked, crumbled or fallen out
- Open joints round the window box
- Modern sealant on a period surround
- Draughty sash windows at the surround
Rented homes near Ayr station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before you book
- Are they insured?
- How the colour is chosen
- When the joint can take water or movement
- Whether all the old sealant comes out first
Why it’s worth doing now in Ayr
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. For landlords in Ayr, damp and leaks can fall under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Frames and glazing around Ayr
Ayr is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you look after a building such as Belmont Academy, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Andrews Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
