Sand mastic in Eccles
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Common call-outs are for a silicone bead on a sash window that spoils the look and open joints round the window box, on brick reveals, period & listed homes and tenement windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Eccles
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
Look out for these signs:
- Crumbling sand mastic round a window
- Open joints round the window box
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
Whether the job is in Eccles itself or nearby, the right material for each joint matters as much as a neat finish.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
FAQs for Eccles
Is Eccles within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do sand mastic in Eccles?
Yes. Our work covers the whole of Scotland, and Eccles is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Should I use sand mastic or silicone?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can old silicone round a sash window be swapped for sand mastic?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Outdoor work around Eccles depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Advice

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Look over the window mastic once a year
- Keep modern sealant off the mastic
- Get any rot dealt with first
- Renew mastic before redecorating the windows
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Sand mastic in Eccles: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
