Sand Mastic in Farleigh Green
Sand mastic across Farleigh Green and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sand mastic for homes and businesses in Farleigh Green
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on tenement windows, sash and case windows and stone surrounds, and the jobs we see most are mastic worn away on windows facing the weather and cement or filler used on old window joints that has cracked.
Mastic can only go onto a dry, clean joint, so window work in Farleigh Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by a 12-month guarantee.

Windows and doors in Farleigh Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Stoneacre (about 4.9 miles east) are a reminder that the area around Farleigh Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as East Farleigh Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
