Cheapest time for wood and fiberglass window replacement in either city

How much should new windows really cost you?
Frame material, glass package and install type decide the price. Our editors on what's worth paying for.
The value case
Double-pane, low-E vinyl is the workhorse spec for a reason: it handles the vast majority of drafts and heat loss without the price jump of premium materials. When you're replacing every window at once and watching the total, it's the default that leaves the least on the table.
The efficiency case
In extreme climates, triple-pane or premium low-E/gas-fill glass pays back in comfort and bills — and ENERGY STAR units may qualify for rebates. Spend on the glass package before the frame upgrade.
The install case
The best window on the market still fails when it's set into a bad opening without proper flashing. If the existing frame is rotted, a full-frame replacement that reseals the opening outlasts a cheap pocket insert every time — let the home's condition, not the lowest bid, decide the method.
If you're trimming a window budget, trim the frame material before the glass package or the installation — those two are where corners actually show up, in comfort and in leaks.
