Sand mastic for homes and businesses in Charing
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We work on period & listed homes, sash and case windows and brick reveals, and the jobs we see most are tired mastic found when preparing windows for paint and a silicone bead on a sash window that spoils the look.
Around Charing, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
All of our work is guaranteed for twelve months.

Landlords, agents and businesses in Charing
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Charing, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. In a smaller place like Charing, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Advice
Why deal with it now?
Replacing sash windows is a big decision for a period home 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. In an older home around Charing, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
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 will explain the quote if you ask.

How the job changes by surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.

Sand mastic in Charing: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Godinton House (about 3.9 miles south-east) are a reminder that the area around Charing has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Church of St Peter and St Paul include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Charing Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Charing station, any sash windows need sound mastic to keep draughts and rain out.

Local landmarks in Charing

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Leave the new mastic unpainted
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
- Avoid heavy scraping on the mastic joint
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- Access and height
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Whether there’s mould to deal with
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- A few photos by email, if you can
- How we’d reach the joints
- The address or postcode of the job
Every job is quoted individually. Just phone 0345 464 0079 or email us with the details, and photos are welcome.
