How To Choose a Window Company in Rock Island

Each window provider has different offerings and approaches. To ease the company search, keep these factors in mind:

Window Cost by Type

When it comes to replacing your windows, value is paramount. Each window you replace should provide top-notch durability at a fair price point. Although top-of-the-line replacement windows may come with a higher initial price tag, they often yield better long-term value due to their extended lifespan. The overall cost of your replacement windows will depend on the specific materials, styles, and sizes you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A window expert can guide you through selecting 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
Glass Block$47-$594

Window Material Cost

You'll also need to pick a window material. Homeowners usually make their selection by considering energy efficiency objectives, the local climate 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

Other Window Replacement Costs

Your total cost for window replacement will also include applicable warranty fees, permit-related costs (if required), and labor. Make sure to discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Call a company representative to learn more about its public and private credentials, guarantees, and experience. Company websites often have photo galleries showing off previous work technicians have done.

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 more varied.

Types of Windows Offered

The type of window you want should influence your company choice. Not every contractor will necessarily be familiar with the window brand you want. A company website will tell more about the varieties of windows it focuses on, such as:

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

Customer Feedback

Perhaps the best way to vet window companies for your job is to read what previous customers have said about them. Read customer reviews on sites such as Trustpilot, Yelp, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Ask people you know who have used the company you're evaluating, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Rock Island

How could new windows help my energy efficiency?

Rock Island homeowners could save up to $320 each year by switching to efficient windows. They'll also lower their property's carbon dioxide emissions by 480 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 retain heat in the wintertime, improving your comfort and furthering your dollar.

How frequently should I upgrade or replace my windows?

Refer to your window warranty to best understand how long your windows are meant to last. Most residential windows can last about 15–20 years. Check your windows for damage, water infiltration, and subpar performance to determine whether you need a replacement.

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

The answer to this question largely depends on your financial situation, how your windows are doing overall, and your plan for your home. A full-window replacement can save you money on energy bills and add value to your home, while replacing windows gradually can be more budget-friendly and let you focus on the windows in the worst condition. Ultimately, it's important to weigh the pros and cons and decide on the method that best fits your needs.
