Sand mastic for homes and businesses in Eton Wick
Across Eton Wick, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you are dealing with open joints round the window box and draughts and rain around sash boxes, we can put it right, on tenement windows, period & listed homes and stone surrounds alike.
Somewhere as small as Eton Wick, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, large or small.

The process
At the end, we look at the finished work together. The work normally takes a few hours for a single window, longer for several, depending on the amount of work. For a village or hamlet like Eton Wick, 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

Landlord and commercial work in Eton Wick
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Common problems we fix in Eton Wick
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
These are the problems we are asked about most:
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
Schools such as Eton Wick CofE First School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Windows and doors in Eton Wick
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Dorney Court (about 1.4 miles west) nearby, there’s older building stock in the area around Eton Wick as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Windsor & Eton Central station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Church of Saint John the Baptist, the joint between an old wall and a newer frame is usually the first place rain gets in.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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 fails, we can still redo it.
