Hampstead Norreys Sand Mastic
We cover Hampstead Norreys for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Old sand mastic that has cracked, crumbled or fallen out
- Open joints round the window box
- Cracked mastic round a front door frame
Different surfaces, different methods
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
About our sand mastic in Hampstead Norreys
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on sash and case windows, stone surrounds and brick reveals, and people most often call us about wind and rain getting in round a sash window and open joints round the window box.
Somewhere as small as Hampstead Norreys, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The number of rooms or windows
- Whether the work is at height
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
Asking for a quote

Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Older cottages and farmhouses around Hampstead Norreys can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Do you need sand mastic in Hampstead Norreys?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The problems people generally mention when they call include:
- Old cement repairs round a window that have failed
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
For an older house near a landmark such as Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Advice

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 chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
