Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
How we handle sand mastic in Stunts Green
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on tenement windows, period & listed homes and sash and case windows, and people most often call us about a silicone bead on a sash window that spoils the look and mastic worn away on windows facing the weather.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stunts Green is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What exactly is sand mastic?

Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Around Stunts Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Decisions on consent for listed homes
- Decayed frames that need repair
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.
