Why it’s worth doing now in Dirleton
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area 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.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
What you get with us

About our sand mastic in Dirleton
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on period & listed homes, tenement windows and stone surrounds, and people most often call us about weathered mastic on the most exposed windows and a silicone bead on a sash window that spoils the look.
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.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep modern sealant off the mastic
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Go gently near the mastic when preparing windows
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
What sand mastic looks like in Dirleton
Dirleton is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
If you look after a building such as North Berwick High School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to North Berwick station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

FAQs for Dirleton
Is sand mastic in a coastal place like Dirleton any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near North Berwick station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is the work guaranteed?
Our 12-month guarantee covers every job, sand mastic included.
Signs you need sand mastic in Dirleton
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Any of these means the joints need attention:
- Mastic that needs renewing before redecorating
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
- Modern sealant on a period surround
In the older streets around Dirleton Parish Church Hall, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
