Sand mastic in Herne Pound
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. Typical jobs include cement or filler used on old window joints that has cracked and open joints round the window box, across sash and case windows, stone surrounds and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Herne Pound is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you are covered after we have gone.

Frames and glazing around Herne Pound
With historic houses such as Old Soar Manor (about 2.5 miles west) nearby, there’s older building stock in the area around Herne Pound as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much 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 Wateringbury station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Mereworth Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Damaged stone surrounds
- Broken panes
- Sashes that need overhauling

Why act early in Herne Pound
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Older cottages and farmhouses around Herne Pound can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

When to call us in Herne Pound
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Look out for any of the following:
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
In the older streets around St Lawrence's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- How long to leave it before use
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
- How much experience the applicator has

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Herne Pound, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- 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.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
