How To Choose a Window Company in St. Louis

With St. Louis' robust local economy, you're sure to find a reliable window replacement company that aligns with your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

When it comes to upgrading your windows, cost-effectiveness is most important. Each window you buy should deliver top-notch durability at a reasonable price point. Although top-of-the-line replacement windows may cost more upfront, they often provide better long-term value due to their extended lifespan. The overall cost of your window replacement will depend on the specific materials, sizes, and styles you need. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. If you're unsure, a window provider can help you determine which options are ideal for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Arched$226-$1,386
Awning$327-$910
Bay$753-$5,585
Custom$335-$931
Casement$261-$1,510
Double-hung$122-$786
Egress$223-$558
Glass Block$45-$565
Picture$196-$1,448
Single-hung$89-$1,489
Skylight$112-$1,345
Sliding$256-$1,303
Storm$53-$368
Transom$273-$571

Window Material Cost

Window prices also vary based on material. Each option provides different benefits depending on the local climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against St. Louis' fierce wind, so they tend to cost more.

Window TypesAverage Cost
Aluminum$53-$1,489
Composite$538-$1,208
Fiberglass$89-$753
Vinyl$181-$1,675
Wood$269-$1,510

Other Window Replacement Costs

Ask each company you're considering about warranty fees, labor costs, and permit fees. This will help you get a better picture of the overall expenses involved in the project.

Experience and Training

The longer a window company has served your area, the better its workmanship will likely be. Speak with a company representative to learn more about its guarantees, experience, and public and private credentials. Company websites often have photo galleries showing off previous work technicians have done.

Licensing and Credentials

Missouri doesn't mandate window installers to get a state license. Instead, counties and cities set their own credentialing standards. Speak to your county government office to see what rules they have for window installers, and look for companies with credible private accreditations in your own research. A few good places to start include certificates from the American Window and Door Institute or Fenestration and Glazing Industry Alliance.

Types of Windows Offered

There are several replacement window types you can choose from, and it's important to find a company that has expertise with the ones you want. Look on a company's website and reviews for any of these types:

Finally, pay close attention to the framing materials that an installer uses. Each window frame material has a different price point, life span and energy efficiency level. A company will usually specify whether the windows they set up use metal, wood, vinyl, composite, or fiberglass.

Customer Feedback

One of the most surefire ways to vet a company is to read what other customers have said about their experiences. Trustworthy sources for customer reviews include Google, Trustpilot, and the BBB Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.
