Sand mastic for sash & case windows in Lochawe, Argyll and Bute
Sand mastic across Lochawe and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed

What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In an older home around Lochawe, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

About our sand mastic in Lochawe
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. If you have draughty sash windows at the surround and mastic dropping out of the joint, we can put it right, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Lochawe is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months.

Advice
Sand mastic in Lochawe: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Lochawe 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.
For landlords with property near Loch Awe station, any sash windows need sound mastic to keep draughts and rain out. Homes close to St Conan’s Kirk include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Lochawe is about 30 miles north-west of Helensburgh, in Argyll and Bute. Jobs in Lochawe get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Lochawe is one of 118 towns and villages in Argyll and Bute we cover for sand mastic. There’s also a page for Glasgow, about 48 miles away.
Postcode districts we cover here for sand mastic: PA33. Local streets include Old Military Road and St Conan's Road.

How the job changes by surface

Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

What else we do in Lochawe
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
