Four quick questions. Most quotes come back the same day.
Ngaio's housing runs heavily to compact timber homes, with a good share of workers cottages from the 1890s to 1930s alongside interwar bungalows. Small footprints, simple joinery and a lot of it still original. The suburb sits in a shaded gully with bush along many boundaries, which keeps humidity up and means timber here stays damp longer after rain than it does on an open north facing slope.
Shade and damp are hard on timber joinery
Ngaio's gully setting and the bush along many sections mean less sun on the joinery and slower drying after rain. Paint film breaks down sooner and rot gets a foothold faster, particularly on south facing elevations that never see direct sun in winter.
The practical advice is dull but it works: keep the paint intact, especially on the sill nose and end grain, and deal with a break in the coating before it lets water into the timber rather than after.
Cottage joinery is small, simple and worth keeping
Workers cottage windows are modest: double hung sashes with plain rails and no decorative work. That makes them cheap to repair and easy to retrofit, because there is no complicated profile to reproduce.
The timber is old growth, so a sill with soft timber at one end usually has decades left in the rest. Scarfing in new wood is quick on a small sash and the repair disappears under paint.
Draughts in a small house
In a compact cottage a single draughty window has a much bigger effect on how the house feels than the same window would in a large home. There is less air volume to buffer it and often only one heat source.
Brush pile draught seals in the sashes plus re rubbering anywhere aluminium has been added over the years is usually the highest value thing we can do here, and it costs a fraction of glazing work.

Window repair in Ngaio: common questions
Why does the joinery on my Ngaio house rot faster than my parents' place?
Shade and slow drying. Bush edged gully sections hold moisture, so paint breaks down sooner and timber stays wet longer after rain.
Is it worth repairing small cottage windows?
Yes. They are simple, the timber is old growth, and repairs are quick. Replacing them costs far more and usually looks wrong on a cottage.
