In Buffalo and Rochester, the first frost has shown up as early as the first week of October. A short checklist now saves you a long, cold list of regrets later.

1. Do the Candle Test

Move a lit candle slowly around each window frame — a flickering flame means air is getting through.

2. Check for condensation between the panes

Fog trapped inside the glass means the seal has failed, and no amount of cleaning will fix it.

3. Inspect frames for rot, warping, and sticking sashes

Windows that won’t open easily in September won’t open at all once moisture swells the wood.

4. Reverse your ceiling fans

Clockwise at low speed pushes warm air back down instead of pulling it up.

5. Book any replacement work now, not in December

Custom-built windows need lead time, so scheduling early is what gets you sealed up before heating season.
