Sand mastic for homes and businesses in Crowhurst Lane End
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you are dealing with gaps where the frame meets the masonry and draughts and rain around sash boxes, we can help, whatever the surface.
In a village or hamlet like Crowhurst Lane End, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What else we do in Crowhurst Lane End
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Honest limits

Historic houses like Titsey Place (about 4.6 miles north-east) are a reminder that the area around Crowhurst Lane End has older buildings as well as new.

When to call us in Crowhurst Lane End
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they generally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Cracked mastic round a front door frame
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
Homes close to Church of St George include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- How long the guarantee is
- Whether you can choose the colour
- Whether VAT is included
- When the joint can take water or movement
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
