About our sand mastic in Crosshill
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. If you have silicone on a period window that looks wrong and mastic round period door frames that has failed, we can help, on sash and case windows, stone surrounds and brick reveals alike.
Outdoor sealant needs a dry surface, so window work around Crosshill is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
- Look over the window mastic once a year
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
