How we handle sand mastic in Sutton Green
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We’re often asked to deal with gaps round a timber door in stone or brick and failed mastic on an exposed elevation, on period & listed homes, stone surrounds and timber door frames.
Mastic can only go onto a dry, clean joint, so window work in Sutton Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Signs you need sand mastic in Sutton Green
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
The problems people generally mention when they call are:
- Old cement repairs round a window that have failed
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
- Gaps between timber frames and stone or brick
For site and facilities teams at buildings such as Hoe Valley School, larger buildings have plenty of frames, and the mastic around each one ages.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a small place like Sutton Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Aftercare tips
A little care helps the new joints last. We recommend:
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
- Leave the new mastic unpainted
Do not 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.
Sutton Green homes and the weather
With historic houses such as Clandon Park (about 3 miles south-east) nearby, there’s older building stock in the area around Sutton Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to All Souls' Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Worplesdon station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
