Sand mastic for homes and businesses in Maiden's Green
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. Common call-outs are for open joints round the window box and silicone on a period window that looks wrong, across sash and case windows, timber door frames and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Maiden's Green is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Advice
What the job involves on each surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
How to look after the new joints
After the cure time, these simple habits help:
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
- Make sure water runs off the sill
- Get any rot dealt with first
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Sand mastic in Maiden's Green: local notes
Historic houses like St Leonard's Hill (about 3 miles north-east) are a reminder that the area around Maiden's Green 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. 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 Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Broken panes
- Sashes that need overhauling

If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Tenement windows
- Period & listed homes
- Sash and case windows
- Brick reveals
- Stone surrounds
- Timber door frames
Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What we’re called out for in Maiden's Green
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
It’s worth asking for a quote if you see:
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
If you let a flat or house near Martins Heron station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before you book
