Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In an older home around Devonside, damp from a failed joint can get into timber and plaster.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

How we handle sand mastic in Devonside
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. We work on timber door frames, tenement windows and brick reveals, and common reasons people get in touch are window mastic to renew ahead of painting and silicone on a period window that looks wrong.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Your job is guaranteed for a year, as with all our work.

Frames and glazing around Devonside
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you let a flat or house near Alloa station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Alva Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs 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 doesn’t move well, and the joint depth matters as much as the finish.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours for a single window, longer for several. Outside jobs in Devonside 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 is not affected.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.

How the job changes by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
