Sand mastic in Dry Sandford
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on timber door frames, tenement windows and brick reveals, and people most often call us about cracked mastic round a front door frame and a silicone bead on a sash window that spoils the look.
Around Dry Sandford, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by a 12-month guarantee, wherever you are in Oxfordshire.

Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Why deal with it now?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Around Dry Sandford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.

Frames and glazing around Dry Sandford
With historic houses such as Appleton Manor (about 1.7 miles north-west) nearby, there’s older building stock in the area around Dry Sandford 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’s traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Helen, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Radley station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Dry Sandford Primary School, the mastic around its windows and doors needs looking after like any other building’s.
