Sand Mastic in Ewhurst Green
Our applicators work in Ewhurst Green on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
How we handle sand mastic in Ewhurst Green
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you’re dealing with window mastic to renew ahead of painting and cement or filler used on old window joints that has cracked, we can put it right.
In a village or hamlet like Ewhurst Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. In a small place like Ewhurst Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

In the older streets around Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Ockley station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Leave it or put it right?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like Ewhurst Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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, and we’ll explain the quote if you ask.
Why us?

Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Signs you need sand mastic in Ewhurst Green
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
Signs it’s time to call us include:
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
- A silicone bead on a sash window that spoils the look
Managing a site like Ewhurst CofE Aided Infant School? Then its window and door frames need their mastic kept sound, just like a home’s.
Comparing quotes
- Whether they’re fully insured
- How the colour is chosen
- Who does the work, and how experienced they are
- What product goes in the joint
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
