Sand mastic in Butt's Green, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you have silicone on a period window that looks wrong and mastic dropping out of the joint, we can help, on sash and case windows, brick reveals and timber door frames alike.
Mastic can only go onto a dry, clean joint, so window work in Butt's Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What sand mastic looks like in Butt's Green
With historic houses such as Danbury Place (about 1.1 miles north-east) nearby, there’s older building stock in the area around Butt's Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as The Sandon School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Beaulieu Park station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Sashes that need overhauling
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Period & listed homes
- Brick reveals
- Tenement windows
- Stone surrounds
- Sash and case windows
- Timber door frames
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Renew mastic before redecorating the windows
- Don’t paint over the new mastic
- Check the mastic when you check the paintwork
- Clear gutters so water does not pour onto the windows
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Different surfaces, different methods
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
