Sand mastic for homes and businesses in Chiddingstone Hoath
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for modern sealant on a period surround and draughts and rain around sash boxes, on tenement windows, sash and case windows and timber door frames.
Mastic can only go onto a dry, clean joint, so window work in Chiddingstone Hoath is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our one-year guarantee in Chiddingstone Hoath and across Kent.

What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Chiddingstone Hoath, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

When to call us in Chiddingstone Hoath
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
Any of these means the joints need attention:
- Gaps between timber frames and stone or brick
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
- Draughts and rain around sash boxes
Historic houses such as Chiddingstone Castle, about 1.6 miles north, show how far back building around Chiddingstone Hoath goes.
What your quote should include
- Whether they seal over old material or remove it
- What the cure time is
- How long the guarantee is
- Whether they’re fully insured
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Keeping the joints in good condition
Looking after new joints is easy:
- Avoid heavy scraping on the mastic joint
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

Chiddingstone Hoath homes and the weather

With historic houses such as Chiddingstone Castle (about 1.6 miles north) nearby, there’s older building stock in the area around Chiddingstone Hoath as well as newer homes.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In a small place like Chiddingstone Hoath, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
