Sand mastic in Dunsfold
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have draughts and rain around sash boxes and silicone on a period window that looks wrong, we can put it right, on period & listed homes, sash and case windows and stone surrounds alike.
Around Dunsfold, 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.
Big or small, you get the same one-year guarantee in Dunsfold and across Surrey.

How it works
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for a single window, longer for several, depending on the size of the job. In a small place like Dunsfold, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Different surfaces, different methods
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.

Dunsfold homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Mary and All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
