How To Choose a Window Company in St. Clair

Reliability is important when it comes to choosing a window installer. However, your chosen company should also suit your needs and appreciate your vision. Keep in mind the following factors during your company search:

Window Cost by Type

When it comes to replacing your windows, cost-effectiveness is king. Each window you replace should provide unparalleled durability at a fair price point. Choosing economy windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The style, size, and material 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 sweeping, custom-size picture window will cost more. If you're unsure, a window specialist can help you decide which options are best for your home.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$194-$1,188
Awning$280-$780
Bay$646-$4,789
Custom$287-$798
Casement$224-$1,295
Double-hung$104-$674
Egress$192-$478
Glass Block$38-$485
Picture$168-$1,242
Single-hung$76-$1,277
Skylight$96-$1,153
Sliding$220-$1,118
Storm$45-$316
Transom$234-$490

Window Material Cost

You'll also need to select a window material. Homeowners frequently make their selection by considering the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost
Aluminum$45-$1,277
Composite$461-$1,036
Fiberglass$76-$646
Vinyl$155-$1,437
Wood$231-$1,295

Other Window Replacement Costs

Your total cost for new windows will also include warranty fees (if applicable), permit application fees, and labor. Ensure that you discuss each of these factors with an estimator before committing to a window company.

Experience and Training

Browse a company's website and contact a representative to learn more about its product and service offerings, pricing, and warranties. Many window companies also keep online photo galleries that highlight past projects.

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been in business, the more likely it will deliver excellent craftsmanship.

Licensing and Credentials

Illinois doesn't issue state contracting licenses to window installers, but cities in the Land of Lincoln might have their own requirements for companies to follow. In Chicago proper, window installers must have a Class D or E license and submit copies of business disclosures for the public record. Outside the Windy City, licensing requirements are not uniform.

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's crucial to find a company that focuses on installing the ones you want. Search a company's website and reviews for any of these types:

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

Customer Feedback

Perhaps the best way to evaluate window companies for your job is to see what previous customers have said about them. You can find customer reviews on websites like Google, Yelp, Trustpilot, and the BBB. Talk to people you know who have used the company you'd like to hire, and ask a representative for professional references.
