Sand mastic for homes and businesses in Bowling
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you are dealing with mastic dropping out of the joint and gaps between timber frames and stone or brick, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Your job is guaranteed for a year, as with all our work.

Do you need sand mastic in Bowling?
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Common reasons people contact us are:
- Cement or filler used on old window joints that has cracked
- Failed mastic on an exposed elevation
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
If you look after a building such as Park Mains High School, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Bowling
Is Bowling within the area you cover?
Yes. Bowling is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Bowling affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we’re fully insured.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

Advice
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What sand mastic looks like in Bowling
Bowling is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

Why deal with it now?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a place like Bowling, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
