Surface by surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
How we handle sand mastic in Gardenhall
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on stone surrounds, brick reveals and timber door frames, and people most often call us about gaps where the frame meets the masonry and patchy fillers round a sash window.
In and around a place like Gardenhall, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
All our work comes with a 12-month guarantee.

Common problems we fix in Gardenhall
Water gets into small cracks in the mastic and pushes it out. Exposed elevations generally fail first.
Look out for these signs:
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Wind and rain getting in round a sash window
- Mastic worn away on windows facing the weather
If you let a flat or house near Hairmyres station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Before booking anyone
- Whether VAT is included
- Whether all the old sealant comes out first
- How hidden problems are handled
- What product goes in the joint
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
- Keep sills and gutters clear so water drains away
- Check with your local planning authority if your home is listed
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

- Sashes that rattle, stick or will not open
- Planning or listed building consent (your local planning authority decides)
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.

Gardenhall homes and the weather
Gardenhall is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Duncanrig Secondary School, its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
The process
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a single window, longer for several. Around Gardenhall, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
