Sand mastic in Auchenhowie
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. Typical jobs include silicone on a period window that looks wrong and gaps where the frame meets the masonry, on tenement windows, stone surrounds and timber door frames.
In and around a place like Auchenhowie, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Big or small, it’s backed by our 12-month guarantee in Auchenhowie and across East Dunbartonshire.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Letting agents and landlords in Auchenhowie can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
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.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. 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.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. Outdoor work around Auchenhowie depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.

What else we do in Auchenhowie
What sand mastic looks like in Auchenhowie
With historic houses such as Tenement House (about 4.7 miles south) nearby, there’s older building stock in the area around Auchenhowie as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is 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.
Homes close to St Paul’s Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Boclair Academy, its window and door frames need their mastic kept sound, just like a home’s.
