How do I stop drafts around my front door?

Replace the door sweep first (the strip along the bottom) — it's the single biggest source of PNW cold air infiltration. Then run a lit candle around the perimeter on a windy day: any flicker is a leak. Foam weatherstripping in the jamb takes 20 minutes and fixes the top and sides.

Why are my windows foggy between the panes?

Fog between the two panes of a sealed insulated window means the seal has failed and moisture is trapped inside. The glass unit (called an IGU) can be replaced without replacing the whole window frame — usually $150–$400 per unit. It won't fix itself and it won't get better.
