About our sand mastic in Steward's Green
Across Steward's Green, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, brick reveals and period & listed homes, and the jobs we see most are crumbling sand mastic round a window and old cement repairs round a window that have failed.
Outdoor sealant needs dry, clean surfaces, so work on frames around Steward's Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Damaged stone surrounds
- Whether work needs listed building consent
- Cracked or broken glass
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Stone surrounds
- Tenement windows
- Brick reveals
- Sash and case windows
- Period & listed homes
- Timber door frames
What we are called out for in Steward's Green
Rain on the window surround works into any crack and pushes it out. Exposed elevations usually fail first.
The most common problems we see are:
- Silicone on a period window that looks wrong
- Mastic worn away on windows facing the weather
- Window mastic to renew ahead of painting
- Gaps between timber frames and stone or brick
If you live in an older home near Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- The length of the guarantee
- Who turns up on the day
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
Steward's Green homes and the weather
With historic houses such as Hill Hall (about 1.6 miles south-east) nearby, there’s older building stock in the area around Steward's Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Ivy Chimneys Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. For a village or hamlet like Steward's Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Older cottages and farmhouses around Steward's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.
