Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a smaller place like Claygate, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Sand mastic for homes and businesses in Claygate
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with failed mastic on an exposed elevation and cement or filler used on old window joints that has cracked, across sash and case windows, stone surrounds and period & listed homes.
Many houses in smaller places like Claygate have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
Our work is backed for twelve months, in Claygate and everywhere else we cover.

Frames and glazing around Claygate
Historic houses like The Homewood (about 2.3 miles west) are a reminder that the area around Claygate has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Claygate station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Claygate Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Make sure water runs off the sill
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.

We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
