Sand mastic in Ridgeway, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. We work on sash and case windows, stone surrounds and timber door frames, and common reasons people get in touch are mastic dropping out of the joint and cement or filler used on old window joints that has cracked.
Homes in small places like Ridgeway often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Frames and glazing around Ridgeway
With historic houses such as Westenhanger Castle (about 3.6 miles south-east) nearby, there’s older building stock in the area around Ridgeway as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Westenhanger station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Smeeth Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Should I use sand mastic or silicone?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you replace silicone on a period window with sand mastic?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. In a small place like Ridgeway, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
- Don’t run silicone over sand mastic
- Check the mastic when you check the paintwork
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Ridgeway, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
