Sandy Balls: your questions answered
Will you come out to Sandy Balls?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is sand mastic in Sandy Balls guaranteed?
All our work, in Sandy Balls and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
How long does sand mastic take?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we’ll say how long yours will take.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll advise.
Sand mastic for homes and businesses in Sandy Balls
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on tenement windows, stone surrounds and period & listed homes, and common reasons people get in touch are mastic that needs renewing before redecorating and draughty sash windows at the surround.
In a village or hamlet like Sandy Balls, 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 one-year guarantee comes as standard.

How it works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. For a village or hamlet like Sandy Balls, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
- Move anything stored near the joints

Advice
Do you need sand mastic in Sandy Balls?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
For site and facilities teams at buildings such as The Burgate School and Sixth Form, its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Sand mastic in Sandy Balls: local notes
Historic houses like Breamore House (about 2.9 miles north) are a reminder that the area around Sandy Balls 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Giles, the joint between an old wall and a newer frame is generally the first place rain gets in.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Look over the window mastic once a year
- Don’t run silicone over sand mastic
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
How the job changes by surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
