Sand mastic for homes and businesses in Uplees
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have weathered mastic on the most exposed windows and mastic round period door frames that has failed, we can put it right, whatever the surface.
In a village or hamlet like Uplees, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work comes with our one-year guarantee, wherever you are in Kent.

Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Uplees can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear price for the lot.

What sealant work cannot fix
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
- Don’t run silicone over sand mastic
- Leave the new mastic unpainted
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a single window, longer for several. Somewhere like Uplees needs a little journey planning: 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.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Uplees homes and the weather
Uplees is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
