Why act early in Auldcathie
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Sand mastic in Auldcathie, done properly
We work across Auldcathie renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on timber door frames, brick reveals and period & listed homes, and people most often call us about cement or filler used on old window joints that has cracked and mastic dropping out of the joint.
In and around a place like Auldcathie, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
A 12-month guarantee comes as standard.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
- Check the mastic when you check the paintwork
- Do not run silicone over sand mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Auldcathie homes and the weather
Auldcathie is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Winchburgh Academy? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Uphall station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

What we are called out for in Auldcathie
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The most common problems we see are:
- Cement or filler used on old window joints that has cracked
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Open joints round the window box
Homes close to Auldcathie Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Different surfaces, different methods
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
How it works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints in most cases. Somewhere like Auldcathie 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.
- 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 finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

Auldcathie questions
Is sand mastic in a coastal place like Auldcathie any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
Do you work for letting agents?
Yes, often. We can quote for several properties at once.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
