How To Choose a Window Company in Downers Grove

With Downers Grove's robust local economy, you're sure to find a trustworthy replacement window company that matches your values and preferences. As you reach out to companies, keep the following factors in mind:

Window Cost by Type

When it comes to upgrading your windows, value is king. Each window you purchase should offer maximum durability at an affordable price point. Choosing economy windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The final cost of your replacement windows will depend on the particular styles, materials, and sizes you need. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. A window expert can help you with choosing the options that fit your preferences.

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$49-$620

Window Material Cost

Materials also help determine a window's cost. You might pick a material based on your desired look, your energy efficiency goals, and the local climate. For example, wooden windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window TypesAverage Cost

Other Window Replacement Costs

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

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Talk with a company representative to learn more about its guarantees, experience, and public and private credentials. 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 towns 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. Outside the Windy City, licensing requirements are not uniform.

Types of Windows Offered

The style of window you prefer should factor into your company choice. Not every installer will necessarily be familiar with the types you want. A company website will tell more about the window types it focuses on, such as:

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

Customer Feedback

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

Frequently Asked Questions About Window Replacement in Downers Grove

How much energy and money will I save by upgrading my windows?

Downers Grove homeowners could potentially save $300 annually by installing efficient windows. They'll also reduce their property's carbon dioxide emissions by 450 pounds per year.

According to the federal Department of Energy, up to a third of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-efficient windows help keep heat out in the summertime and in during the wintertime, both protecting your comfort and saving you money.

What is the maintenance schedule for an average window, and how long will it last?

Windows don't have an indefinite lifespan, and most vinyl models are built to serve your home for 15 to 20 years. Over time, weatherproofing materials weaken, framing shifts, and window coatings lose their efficacy. These changes result in condensation, air leaks, energy loss, and other expensive problems necessitating repair or replacement.

Is it better to replace all my windows at once, or just a few at a time?

To form a window replacement strategy, consider your finances, home improvement goals, and energy efficiency targets. A gradual replacement helps you save money and prioritize the windows that need the most attention, but you'll also notice smaller gains in efficiency. A complete window replacement will require a larger investment up front, but you'll see a more noticeable energy efficiency improvement.
