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$225-$1385
Awning$326-$909
Bay$752-$5583
Custom$335-$930
Casement$260-$1509
Double-hung$121-$785
Egress$223-$557
Glass Block$44-$565
Picture$196-$1447
Single-hung$88-$1489
Skylight$111-$1344
Sliding$256-$1302
Storm$52-$368
Transom$272-$570

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$52-$1489
Composite$537-$1207
Fiberglass$88-$752
Vinyl$181-$1675
Wood$268-$1509

Other Window Replacement Costs

Ask each window installer you're evaluating about labor costs, warranty fees, and permit fees. This will help you understand the total costs involved in the project.

Experience and Training

The longer a window company has been in business, 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.

Frequently Asked Questions About Window Replacement in St. Louis

What are the benefits of hiring a window installer?

By working with a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team is well-equipped with the right supplies and training to do the job safely and accurately. You can also get fast, informed answers to your questions and personalized help to maximize your new windows' potential.

What time of year should I replace my windows?

There is no one-size-fits-all time to upgrade your windows, but some seasons might be better than others depending on the local climate and a company's demand. St. Louis experiences average winters, so anytime in the spring, summer, or early fall will maximize your comfort during the process.

Will my window company install blinds?

Whether a company can sell and install blinds ultimately depends on your state's licensing requirements and the company's own preferences. Many jurisdictions require window covering installers to get a separate license, and not every installer will carry one. If you'd like blinds with your new windows, ask a company representative if its crews can handle the cutting and installation. If a company can't work with blinds, they could refer you to another company or subcontract the work.
