How To Choose a Window Company in Wentzville

Trustworthiness is important when it comes to choosing a window company. However, your chosen company should also suit your priorities and understand your vision. Consider the following factors during your company search:

Window Cost by Type

When you're shopping for replacement windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing cheap windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The style, material, and size of your replacement windows are the most significant factors in your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. If you're undecided, a window company can help you figure out which options are most suitable 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-$5,584
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-$1,344
Sliding$256-$1,303
Storm$53-$368
Transom$273-$571

Window Material Cost

Window prices also vary based on material. Each option offers different benefits depending on the local climate and energy efficiency needs. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, 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 contractor you're evaluating about warranty fees, labor costs, and permit fees. This will help you understand the financial commitment involved in the project.

Experience and Training

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

Licensing and Credentials

Missouri doesn't mandate window companies to get a state license. Instead, cities and counties set their own licensing requirements. Speak to your city hall to see what rules they have for window installers, and look for businesses with trusted 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

The type of window you want should factor into your company choice. Not every installer will necessarily be familiar with the window styles you want. A company website will provide more about the styles of windows it deals with, such as:

Finally, pay close attention to the 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 wood, vinyl, metal, composite, or fiberglass.

Customer Feedback

Reading other customers' stories is one of the best ways to screen window companies in your area. Read customer reviews on sites such as Trustpilot, Yelp, and Google. 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.
