Sand mastic for homes and businesses in Polton
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We are often asked to deal with modern sealant on a period surround and window mastic to renew ahead of painting, on sash and case windows, stone surrounds and tenement windows.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, it’s backed by our 12-month guarantee.

Common problems we fix in Polton
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
It’s worth asking for a quote if you see:
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
Letting a property close to Eskbank station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Why it’s worth doing now in Polton
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. In an older home around Polton, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
Why us?
- A 12-month guarantee on all work
- Fully insured
- Sanitary silicone with an anti-fungal additive in wet areas
- ARBOMaster approved applicator
Frames and glazing around Polton
With historic houses such as Melville Castle (about 2 miles north-east) nearby, there’s older building stock in the area around Polton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Managing a site like Lasswade High School Centre? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Leaonard's Episcopal Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Will you come out to Polton?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

Yes. Tell us about everything you’d like done and we’ll quote it together.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. Outdoor work around Polton depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
