Keeping the joints in good condition
Aftercare is simple:
- Clear gutters so water doesn’t pour onto the windows
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Sort the mastic before the decorators arrive
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

Advice
Different surfaces, different methods
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
DIY sealant or a professional job?
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.
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.
Windows and doors in Crocketford
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For jobs in and around Crocketford, choosing the right material for each joint is as important as a tidy finish.

Do you need sand mastic in Crocketford?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
In and around Crocketford, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What else we do in Crocketford
Leave it or put it right?
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. Around Crocketford, water from a failed joint in an older stone home can soak into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
