How To Choose a Window Company in Thornton

With Thornton's robust local economy, you're sure to find a trustworthy window replacement company in line with your values and preferences. As you gather estimates, keep the following factors in mind:

Window Cost by Type

When it comes to window replacement, cost-effectiveness is most important. Each window you purchase should provide top-notch durability at an affordable price point. Although premium windows may come with a higher initial price tag, they often provide better long-term value due to their increased lifespan. The style, size, and material of your replacement 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 sweeping, custom-size picture window will cost more. It's recommended to consult a reliable window installer to decide on your ideal options.

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

Window TypesAverage Cost
Glass Block$47-$601

Window Material Cost

Window prices also vary based on material. Each option gives you unique advantages 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 in Thornton's strong storms, so they tend to cost more.

Window TypesAverage Cost

Other Window Replacement Costs

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

Experience and Training

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

  • How long it's been in business
  • Photo galleries of completed projects
  • Privately-issued certificates attesting to its workmanship
The more experience a company has, the better its service and workmanship.

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 their business filings for the public record. Beyond the Windy City, licensing requirements are not uniform.

Types of Windows Offered

The style of window you prefer should influence your company choice. Not every installation crew will necessarily be familiar with the window brand you want. A company website will reveal more about the styles of windows it focuses on, such as:

Equally important to your desired windows' shape is their framing. Ask your window provider if it offers the frame material you want, such as aluminum, wood, fiberglass, vinyl, or composite.

Customer Feedback

Perhaps the best way to screen window companies for your job is to find out what previous customers have said about them. You can find customer reviews on websites like Trustpilot, the BBB, Google, and Yelp. 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.

Frequently Asked Questions About Window Replacement in Thornton

What are the benefits of hiring a window installer?

By working with a professional, you don't need to worry about measurement missteps or lacking the right tools. A window installation crew is well-equipped with the right tools and skills to do the job safely and precisely. You can also get fast, informed answers to your questions and tailored guidance to make the most of your new windows

I've heard there are tax credits for energy-efficient windows. How much could I save?

Ultimately, the tax incentives you can claim are determined by the scope of your window replacement and where you are. You can claim 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to contact your local utility for more information on tax breaks specific to your area.

What's the typical timeline for a professional window replacement?

The length of a window replacement project depends on several factors. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes around an hour per window. Keep in mind, larger windows or more complex installations may require additional time.
