New windows can make a home quieter, more comfortable and easier to heat and cool, but they're a major investment. Prices vary widely depending on material, size, style and installation method, so it pays to understand what you're comparing before collecting quotes.

Typical installed costs

These are broad U.S. ranges for a standard-size double-hung window, including professional installation. Large, custom-shaped or specialty windows cost more.

Frame materialTypical installed cost per windowNotes
Vinyl$500–$1,200Most popular; low maintenance, good efficiency
Fiberglass$800–$1,800Strong and stable; can be painted
Wood or wood-clad$900–$2,500+Classic look; needs more upkeep unless clad
Aluminum$500–$1,300Durable but conducts heat; best in mild climates

Insert vs. full-frame replacement

An insert (pocket) replacement fits a new window into the existing frame. It's faster and cheaper, and the interior and exterior trim usually stays in place, but it slightly reduces the glass area. A full-frame replacement removes everything down to the rough opening. It costs more but lets the installer fix rot, add proper flashing and insulation, and change the size or style. If the existing frames are soft, rotted or out of square, full-frame is the right call.

How to read the energy label

Look for the NFRC label on every window and the ENERGY STAR rating for your climate zone.

  • U-factor: how well the window keeps heat in. Lower is better, and it matters most in cold climates.
  • Solar heat gain coefficient (SHGC): how much of the sun's heat comes through. Lower is better in hot, sunny climates; a moderate value can help in the North.
  • Low-E coatings and gas fills (argon or krypton) between panes improve both numbers. Triple-pane glass costs more but can pay off in very cold regions.

Repair, restore or replace?

Not every drafty window needs replacing. Weatherstripping, new sash cords, glazing putty and storm windows can dramatically improve older wood windows for far less money. Replacement makes more sense when frames are rotted, insulated glass units have failed (you see fog or condensation between the panes that you can't wipe away), or windows no longer open and lock safely.

Ways to save

  1. Get at least three written quotes for the same product line, quantity and installation type.
  2. Replace the worst windows first rather than the whole house at once.
  3. Stick with standard sizes and styles where possible; custom shapes add a lot.
  4. Ask your utility and state energy office about rebates for ENERGY STAR windows.
  5. Read the warranty carefully, covering both the product and the installation labor.

Don't expect new windows to pay for themselves quickly through energy savings alone; comfort, noise reduction and curb appeal are part of the value. If drafts are your main concern, start with the low-cost steps in our guide to winterizing your home.

Prices are typical U.S. ranges and vary by region, home and contractor. Always get several local quotes and follow local building codes; hire a licensed professional for electrical, gas and structural work.
