Sand mastic in Hampers Green
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. Typical jobs include mastic round period door frames that has failed and tired mastic found when preparing windows for paint, across sash and case windows, period & listed homes and timber door frames.
Homes in small places like Hampers Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. In a small place like Hampers Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed

Common problems we fix in Hampers Green
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Look out for any of the following:
- Cracked mastic round a front door frame
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Open joints round the window box
If you live in an older home near The Church of St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.

What sand mastic looks like in Hampers Green
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Petworth House (about 0.6 miles south) nearby, there’s older building stock in the area around Hampers Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Petworth Cof E Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Pulborough station, any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
Aftercare is simple:
- Do not run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Hampers Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
