A Guide to Replacing Windows in St. Louis: What Homeowners Need to Know

Windows do more than just let the light in—they impact your home’s comfort, energy efficiency, and even its curb appeal. If you live in the St. Louis metro area and your windows are drafty, foggy, or just plain outdated, it might be time for a replacement.
A white-framed window with four panes, each showing a different season—spring blooms, summer greens, autumn orange leaves, and winter snow—is the perfect inspiration for your Complete Guide to Replacing Windows.

At Chaney Windows & Doors, we know that window replacement is a big decision, and it can feel overwhelming. That’s why we’ve put together this complete guide to help you understand your options, prepare for the process, and feel confident every step of the way.


When Should You Replace Your Windows?

If you're wondering whether it's really time to replace your windows, here are a few telltale signs:

  • Drafts or temperature swings near windows
  • Condensation or fog between panes
  • Windows that stick, won’t open, or don’t lock properly
  • Noticeably high energy bills
  • Wood rot, warping, or cracked frames
  • Outdated look or poor curb appeal

In Missouri’s four-season climate, energy efficiency is a major concern. Old windows often lack modern insulation technology, which can make it harder—and more expensive—to keep your home comfortable.


What Types of Windows Are Best for St. Louis Homes?

When choosing new windows, you'll want to consider:

  • Material: Vinyl is low-maintenance and cost-effective. Wood offers a traditional look but requires more upkeep. Fiberglass is durable and energy efficient.
  • Glazing: Double- or triple-pane windows with Low-E coatings help regulate temperature and block UV rays.
  • Style: From double-hung to picture windows, your choice depends on ventilation needs, aesthetic, and room function.

At Chaney Windows & Doors, we are a Provia Platinum Dealer and we only install high-quality, durable windows that are proven to perform in Missouri’s hot summers and cold winters.

Chaney Door exceeds expectations! Not only is the product itself superior, Kevin and the crew were fantastic. They did an excellent job with installation, made excellent recommendations and the clean up after installation was excellent. I highly recommend this company if you are looking for superior quality and workmanship. On top of that, the crew was so very polite and respectful. Five stars is really not sufficient 🙂
