How we handle sand mastic in Headley
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. If you’re dealing with patchy fillers round a sash window and mastic worn away on windows facing the weather, we can put it right, on brick reveals, tenement windows and period & listed homes alike.
Homes in small places like Headley often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our one-year guarantee.

Frames and glazing around Headley
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Polesden Lacey (about 4.5 miles south-west) nearby, there’s older building stock in the area around Headley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Tadworth station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Schools such as St Andrew's Catholic School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the job changes by surface
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
- Clear gutters so water does not pour onto the windows
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on.
