About our sand mastic in Mintlaw
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 and built up by hand. On older homes, it suits the building far better than silicone. Common call-outs are for silicone on a period window that looks wrong and weathered mastic on the most exposed windows, across sash and case windows, timber door frames and tenement windows.
In and around a place like Mintlaw, 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.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Work for landlords, hotels and businesses
Landlords and letting agents in Mintlaw can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
Frames and glazing around Mintlaw
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Managing a site like Mintlaw Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

Aftercare tips
To keep the joints looking good and working properly:
- Have rotten timber repaired before new mastic goes in
- Renew mastic before redecorating the windows
- Do not run silicone over sand mastic
- Ask us before painting near the mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. Outside jobs in Mintlaw need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Advice
Common questions in Mintlaw
Is Mintlaw in your area for sand mastic?
Yes. We work across all of Scotland, and Mintlaw is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Mintlaw?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
When to call us in Mintlaw
Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.
Look out for any of the following:
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
In and around Mintlaw, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
