About our sand mastic in Drayton St Leonard
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. Common call-outs are for draughts and rain around sash boxes and weathered mastic on the most exposed windows, across timber door frames, period & listed homes and brick reveals.
Around Drayton St Leonard, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Frames and glazing around Drayton St Leonard
Historic houses like Clifton Hampden Manor (about 3.1 miles west) are a reminder that the area around Drayton St Leonard has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Culham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Older cottages and farmhouses around Drayton St Leonard can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What we are called out for in Drayton St Leonard
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
Most people get in touch when they notice something like this:
- Mastic that needs renewing before redecorating
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
- Mastic round period door frames that has failed
For an older house near a landmark such as Church of St Leonard, the joint between an old wall and a newer frame is generally the first place rain gets in.

Common questions in Drayton St Leonard
I let a flat near Culham station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Drayton St Leonard?
Yes. Drayton St Leonard is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Do you have insurance?
Yes. We’re fully insured.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Keeping the joints in good condition
Aftercare is simple:
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
