About our sand mastic in Stoneleigh
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, timber door frames and tenement windows, and people most often call us about cement or filler used on old window joints that has cracked and old sand mastic that has cracked, crumbled or fallen out.
Houses in smaller places like Stoneleigh can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
Every job is covered by our 12-month guarantee.

Why it’s worth doing now in Stoneleigh
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In an older home around Stoneleigh, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Can I do it myself?
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Common problems we fix in Stoneleigh
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
Most people get in touch when they notice one of these:
- Wind and rain getting in round a sash window
- Open joints round the window box
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
Homes close to The Parish Church of St John the Baptist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sand mastic looks like in Stoneleigh
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Fitznells Manor (about 0.8 miles south) are a reminder that the area around Stoneleigh 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.
Managing a site like Auriol Junior School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Stoneleigh station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Aftercare tips
To keep the joints looking good and working properly:
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
- Do not run silicone over sand mastic
- Make sure water runs off the sill
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
