- Mastic that needs renewing before redecorating

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How we handle sand mastic in Oad Street
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on brick reveals, tenement windows and stone surrounds, and people most often call us about cracked mastic round a front door frame and silicone on a period window that looks wrong.
Around Oad Street, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

Frames and glazing around Oad Street
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.
For an older house near a landmark such as Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Borden Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
