Window and Glass Repair in Khandallah, Wellington

The Mount Kaukau anemometer sits directly above this suburb, and during the June 2013 storm it recorded a gust of 202 km/h, the highest reading of that event anywhere in the country. Nothing about window specification in Khandallah is theoretical. Sites on the upper slopes sit in the higher council wind zones, which changes glass thickness, fixing centres and flashing detail.

What the wind zone means for your quote

Wellington City Council maps wind zones from Low through to Specific Design. Elevated and exposed Khandallah sites commonly fall in the upper bands, and windows are tested to NZS 4211 against those pressures, with an Extra High rating covering site wind speeds up to 55 metres per second.

Higher pressure means thicker glass and closer fixings. It also means heavier sashes, which flows through to the stays and hinges. We look the zone up for the address before ordering, and it is the reason a Khandallah quote can differ from an identical window in a sheltered street.

Hardware fails before glass does

The wind rarely breaks a pane directly. It catches a sash on the latch, overloads the friction stay, and the sash swings through the frame. Once a stay has been forced it has fatigued and will fail again.

On exposed Khandallah elevations we replace with heavy duty stays and fit restrictors as a matter of course. It costs very little at the time and it breaks the cycle of repeat repairs.

Steep sections, poor access, careful planning

Khandallah houses are cut into the hillside, and back elevations often drop away steeply. Reaching a second storey window at the low side can need a ladder from a platform or, occasionally, scaffolding.

That gets assessed at the quote and not on the morning. Photographs from the street and from the back, sent with your enquiry, usually tell us enough to give you a real number before we visit.
