Keeping a Buffalo Home Warm Through a Lake-Effect Winter

Published July 1, 2026

Every Buffalo homeowner knows the moment the wind shifts off Lake Erie and the first real lake-effect band rolls in. If your house has old windows, you feel it in the rooms near the glass long before the snow stops. The good news is that most heat loss is fixable, and summer is the smart time to plan the work. Here is what to watch for and how to get ahead of the cold.

Feel for the Draft

Stand by each window on a breezy day and hold the back of your hand near the sash and the frame edge. A noticeable cold stream means the weatherstripping or the seal has given up. On an older Elmwood Avenue double, drafts often show up first at the meeting rail where the two sashes overlap. That air movement is heat leaving and money with it.

Look for Fog Between the Panes

Condensation trapped inside an insulated glass unit is a sure sign the seal has failed and the argon fill is gone. Once that happens, the window is doing little better than a single pane against a January night. You cannot squeegee it away, and it will only spread. Foggy glass is the clearest signal it is time for a new unit.

Match the Glass to the Climate

Not every window needs the same package. For walls that face the wind, low-E glass with argon fill and a low U-factor makes the biggest difference, and our energy-efficient windows are built to those targets. For a sheltered south wall, a quality double-pane window may be all you need. The NFRC label on each unit lets you compare before you decide.

Seal the Whole Opening, Not Just the Glass

A great window still leaks if the rough opening around it is not insulated and flashed. That is why we foam the perimeter and flash each opening to shed the meltwater that runs down a Buffalo wall in a thaw. Skipping that step is how cold air sneaks in behind good glass.

Plan the Work Before the Freeze

Windows are built to order, so the smart move is to measure in the warmer months and install before the first hard freeze. That way your home is buttoned up when the lake-effect season arrives, not waiting on a crew in the middle of it. A quick in-home measure turns guesswork into a plan.
