How To Choose a Window Company in Grafton

It's essential to find a window installer that meets your individual values, needs, and preferences. Consider the following areas during your hunt:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with quality is vital. Although premium replacement windows may be more expensive to buy, they often yield better long-term value due to their longer lifespan. The total cost of your window replacement will depend on the particular sizes, styles, and materials you need. 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. A window expert can help you with choosing the solutions that fit your preferences.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window TypesAverage Cost
Glass Block$47-$594

Window Material Cost

Replacement window prices also vary based on material. Each option offers unique advantages depending on your climate and energy efficiency needs. Vinyl and fiberglass 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

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit application fees, and labor. Ensure that you discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

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

Licensing and Credentials

Illinois doesn't issue state contracting licenses to window installers, but municipalities 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. Beyond the Windy City, licensing requirements are different.

Types of Windows Offered

There are many replacement window types you can choose from, and it's vital to find a company that has expertise with the ones you want. Search a company's website and reviews for any of these types:

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

Customer Feedback

Perhaps the best way to screen window companies for your job is to find out what previous customers have said about them. Trustworthy sources for customer reviews include Trustpilot, the BBB, and Google Speak with people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Grafton

What are the benefits of hiring a window installer?

Window replacement is a big expense that greatly impacts your home's livability and energy efficiency. Hiring a professional window company to manage your project ensures your windows will fit correctly, perform efficiently, and be well-sealed. Companies also typically include a guarantee that addresses required maintenance and most needed fixes.

What should I do if a window is molding or has rot?

A window frame with mold or rot indicates a moisture issue. You might not have to replace the entire window. Instead, a simple framing job could do. It's recommended to consult a specialist to ensure correct sealing and weatherproofing.

How can I gauge the quality of a replacement window?

You can gauge the quality of a replacement window by examining some crucial numbers, including the following:
  • Air leakage rating, which indicates how tight a window's seal is
  • Condensation resistance, which shows how a window manages moisture
  • U-factor, which measures a window's temperature-insulating capability
  • Visible transmittance, which determines how much light passes through a window
  • Solar heat gain coefficient, which evaluates how much heat from sunlight can pass through the window
