Factors That Influence Window Replacement Costs

Window pricing may be confusing, especially if it’s your first time shopping or purchasing your items for your new home. To help you familiarize yourself with the costs and how they are affected as a whole, read this replacement windows guide.

Window Replacement Cost

  • Frame type or material: It can be noted that wood and fiberglass frames may cost a lot more than vinyl. However, vinyl is more cost-effective than wood and fiberglass. It still offers significant benefits, such as low maintenance and durability.

  • Glass type: Windows with a single pane of glass should always be cheaper than those with two or three panes of glass. However, the energy efficiency benefits of having multiple glass panes make double- and triple-pane windows well worth the investment.

  • Installation type: Costs for installation depend on which type you choose. Full-frame replacements are usually more expensive compared to simple insert installations. This is because this type requires a window company to remove your old window entirely.

  • Window type: There could be specific designs and styles that are cheaper than others. Bay windows, for example, will almost always be more expensive than a casement window particularly because of their size.

  • Location inside your home: The space within your home may affect installation and unit costs. For example, your window in the receiving area will have greater square footage than a pantry window. Most of the time, a bedroom window will have an opening mechanism, whereas hall windows could be simple and without opening.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
