About our sand mastic in Warren Row
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with crumbling sand mastic round a window and cracked mastic round a front door frame, on tenement windows, timber door frames and period & listed homes.
Somewhere as small as Warren Row, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a 12-month guarantee.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Go gently near the mastic when preparing windows
- Ask us before painting near the mastic
- Plan mastic work ahead of painting
- Inspect the joints round the windows every year or so
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Why act early in Warren Row
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Warren Row can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Why book with us
- We leave the area clean and tidy

What the job involves on each surface
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Planning or listed building consent (your local planning authority decides)
- Sashes that rattle, stick or won’t open
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Sash and case windows
- Tenement windows
- Timber door frames
- Stone surrounds
- Period & listed homes
- Brick reveals
Common problems we fix in Warren Row
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
These are the problems we are asked about most:
- Gaps between timber frames and stone or brick
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
- Draughty sash windows at the surround
If you live in an older home near St Paul's Mission Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Frames and glazing around Warren Row
Historic houses like Harleyford Manor (about 2.4 miles north) are a reminder that the area around Warren Row has older buildings as well as new. 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Shiplake station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Knowl Hill Church of England Primary Academy, the mastic around its windows and doors needs looking after like any other building’s.
