Sand mastic in Ewshot
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We are often asked to deal with gaps between timber frames and stone or brick and draughts and rain around sash boxes, on timber door frames, sash and case windows and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Ewshot is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with a one-year guarantee.

What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Ewshot, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Ewshot, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Advice
Frames and glazing around Ewshot
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Farnham Castle (about 1.9 miles south-east) nearby, there’s older building stock in the area around Ewshot as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around St Mary's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as St Nicholas' School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Farnham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- How easy the joints are to reach
- The type of sealant required
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Whether it’s a home or a business
- Where the job is, and your postcode
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.

What else we do in Ewshot
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the window mastic once a year
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Have rotten timber repaired before new mastic goes in
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Surface by surface
Tenement and terrace windows
Upper-floor windows need access planning. Let us know the floor and we will confirm access.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
