Sand mastic for homes and businesses in Anna Valley
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you’re dealing with mastic that needs renewing before redecorating and patchy fillers round a sash window, we can help, on sash and case windows, timber door frames and period & listed homes alike.
Homes in small places like Anna Valley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All our work comes with our 12-month guarantee, wherever you are in Hampshire.

How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a single window, longer for several, including the tidy-up. For a village or hamlet like Anna Valley, 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 look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Signs you need sand mastic in Anna Valley
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
People normally contact us after spotting one of these:
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Tired mastic found when preparing windows for paint
- Cement or filler used on old window joints that has cracked
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

For site and facilities teams at buildings such as Balksbury Junior School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Andover station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not paint over the new mastic
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
- Get any rot dealt with first
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
