Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
What sand mastic looks like in Pitchcott
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Waddesdon Manor (about 3.7 miles south-west) are a reminder that the area around Pitchcott 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.
If you look after a building such as Whitchurch Combined School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St. Giles include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Where a wall is exposed, as many are in small places like Pitchcott, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before work begins.
