About our sand mastic in Hale Green
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you’re dealing with failed mastic on an exposed elevation and window mastic to renew ahead of painting, we can put it right, on timber door frames, brick reveals and sash and case windows alike.
Around Hale Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Aftercare tips
Aftercare is simple:
- Ask us before painting near the mastic
- Check with your local planning authority if your home is listed
- Ask a joiner to look at soft timber first
- Renew mastic before redecorating the windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.

What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.

What sand mastic looks like in Hale Green
Historic houses like Horselunges Manor (about 2.4 miles south-east) are a reminder that the area around Hale Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Chiddingly Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. Somewhere like Hale Green needs a little journey planning: 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 start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
