Sand Mastic in Pett Bottom
Our applicators work in Pett Bottom on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

How we handle sand mastic in Pett Bottom
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include draughty sash windows at the surround and failed mastic on an exposed elevation, across brick reveals, stone surrounds and sash and case windows.
Around Pett Bottom, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Make sure water runs off the sill
- Get any rot dealt with first
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

What sand mastic looks like in Pett Bottom
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.
If you look after a building such as Simon Langton Grammar School for Boys, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
