Sand mastic in Staplehurst, done properly
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include cracked mastic round a front door frame and tired mastic found when preparing windows for paint, on timber door frames, period & listed homes and sash and case windows.
Many houses in smaller places like Staplehurst have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. Parking around Staplehurst is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Letting a property close to Staplehurst station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common problems we fix in Staplehurst
Rain on the window surround works into any crack and loosens it further. Exposed elevations usually fail first.
People normally contact us when they notice something like this:
- Patchy fillers round a sash window
- Weathered mastic on the most exposed windows
- Open joints round the window box
- Wind and rain getting in round a sash window
If you look after a building such as Staplehurst School, the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
