Windows that will not open in a Mickleham rental

A stuck or locked window can touch three rental standards at once. How windows, ventilation and fresh air are judged in a Mickleham home.

In short: The windows standard asks for a working latch on every outside window that opens. A window that cannot be opened at all can also leave a room without the ventilation the Building Code expects, and wet areas need a fan that actually reaches outside.

The latch test

Each external window that can be opened must be able to be held closed with a latch. We open and close each window by hand and note any with a missing, loose or broken catch.

Stuck is a different problem

Windows painted shut, locked with a lost key or jammed in their tracks pass the latch test in a sense, because they cannot be opened. But a bedroom whose only window will not open may no longer be ventilated to Building Code requirements, which is its own standard.

Wet areas and the exhaust fan

Where a bathroom or laundry relies on an exhaust fan, the fan has to take the air somewhere. A fan left unducted in the roof sends moist air into the ceiling space, where it condenses on the underside of the roof.

Fix order

Free stuck windows first, then replace missing latches, then deal with any fan ducting. All three are small trade jobs that can be done in the gap between leases.

FAQ

Questions Mickleham owners ask about this

Do window locks count as latches?

A keyed window lock that holds the window shut does the job of a latch. What matters is that the window can be secured closed.

Will you open every window?

Every window we can safely reach. Any we could not get to are listed in the report.

Can you see where the exhaust fan duct goes?

Where the roof space is safely accessible, yes. We note whether the duct ends outside or stops inside the roof.

Is condensation on windows a fail?

Condensation on its own is not. Mould around window frames caused by a building defect, such as a leak, is part of the mould and damp standard.
