Picking Windows for the Washington Climate
Winter lows near 26°F and warm summers mean the glass works year round. A balanced Low-E coating is the right call; skip it only to hit a tight budget.
Climate regions run from 1 (cool) to 5 (hot); Washington sits in region 2.
Humid weather brings condensation and mildew at the sill. New sealed units help, but ask the installer to check the old sill and framing for soft wood before the new window goes in.
Gentle winters and summers keep heating and cooling loads small. Choose windows for looks, easy cleaning and noise, and keep the standard Low-E coating for sun control.
In wildfire country, the glass type is a code question. Tempered panes resist heat cracking far better than standard glass; check your local fire zone map before you approve a quote.
Order early. Units are built to your measurements, and the factory queue usually sets the start date more than the weather does.
Reading Window Estimates in Washington
Line up bids on equal terms. These are the details that explain most of the gap between quotes:
- Rot check. Ask what happens, and what it costs, if the old sill or framing is soft once the sash comes out.
- Crew. Find out if the seller installs with its own staff or a subcontractor.
- Better build. A stronger frame and sash adds about $1,280 for 10 windows here; ask what it buys you.
