How To Choose a Window Company in St. Louis

With St. Louis' sheer size, you're sure to find a reliable window company that aligns with your values and preferences. As you gather estimates, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a significant undertaking, so balancing cost with value is vital. Choosing budget windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The material, style, and size of your new windows are the most significant factors in your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. An installer can guide you through selecting the solutions that fit your requirements.

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

Window Types Average 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 your climate and energy-saving goals. Vinyl and fiberglass 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 Types Average Cost
Aluminum $52-$1489
Composite $537-$1207
Fiberglass $88-$752
Vinyl $181-$1675
Wood $268-$1509

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to assess the cost of labor, guarantees, and any other additional costs that your project may require.

Experience and Training

The longer a window provider has been in business, the better its workmanship will likely be. Contact a company representative to learn more about its experience, guarantees, and public and private credentials. Company websites often keep photo galleries demonstrating previous work technicians have done.

Licensing and Credentials

Missouri doesn't mandate window providers to get a state license. Instead, counties and cities set their own licensing requirements. Consult with your city government to see what regulations they have for window installers, and look for businesses with reliable private accreditations in your own research. A few good places to start include credentials from the American Window and Door Institute or Fenestration and Glazing Industry Alliance.

Types of Windows Offered

The kind of window you desire should play a role in your company choice. Not every installation crew will necessarily be familiar with the types you want. A company website will provide more about the kinds of windows it specializes in, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the framing materials that a provider uses. Each frame material has a different energy efficiency level, life span and price point. A company will usually specify whether the windows they place use composite, metal, fiberglass, vinyl, or wood.

Customer Feedback

One of the best ways to screen a company is to read what other customers have said about their experiences. Read customer reviews on sites such as Google, Yelp, and Trustpilot. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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.
