How To Choose a Window Company in Florissant

It's crucial to find a window installer that meets your specific values, needs, and preferences. Consider the following points during your search:

Window Cost by Type

When you're shopping for new windows, it's essential 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, due to their shorter lifespan and more intensive maintenance needs. The style, material, and size of your replacement windows have the greatest impact on your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. An installer can help you with choosing 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 TypesAverage Cost
Arched$237-$1,452
Awning$342-$953
Bay$789-$5,851
Custom$351-$975
Casement$273-$1,582
Double-hung$127-$823
Egress$234-$584
Glass Block$47-$592
Picture$205-$1,517
Single-hung$93-$1,560
Skylight$117-$1,409
Sliding$269-$1,365
Storm$55-$386
Transom$286-$598

Window Material Cost

Window prices also vary based on material. Each option offers unique advantages depending on your climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost
Aluminum$55-$1,560
Composite$563-$1,266
Fiberglass$93-$789
Vinyl$190-$1,755
Wood$282-$1,582

Other Window Replacement Costs

Your total cost for window replacement will also include applicable warranty fees, permit application fees, and labor. Be sure to discuss each of these elements with an estimator before committing to a window company.

Experience and Training

Select a company that focuses on window installation and repair, and look for this information on its website:

  • How long it's been serving the Florissant area
  • Photo galleries of projects its crews completed
  • Official non-government certifications attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

Missouri doesn't mandate window companies to get a state license. Instead, counties and cities set their own licensing requirements. Check with your county government office to see what regulations they have for window installers, and look for companies with credible 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 type of window you want should factor into your company choice. Not every installation crew will necessarily be familiar with the window styles you want. A company website will reveal more about the varieties of windows it specializes in, such as:

Also, check the type of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include vinyl, aluminum, composite, wood and fiberglass.

Customer Feedback

Reading other customers' stories is a great way to screen different window replacement companies. Trustworthy sources for customer reviews include Google, Yelp, and Trustpilot Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.
