How Installing Energy-Efficient Windows in Rockford Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Rockford

Each window replacement company provides various services and has varying prices based on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Rockford can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost varies depending on several factors, like the location of your home, size, number of windows, type, material and more.

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Rockford homeowners $318+ a year when replacing single-pane windows.

We advise requesting free quotes from multiple window installers to find the one that works best for you.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company can advise you on the best type for your project. In Rockford, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Rockford

EcoWatch differs from other reviewers because we examine these companies through a sustainability lens. We’ve decided to assess the best window installation companies in Rockford mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Rockford area so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Rockford, IL Window Replacement FAQs

How much should window installation cost?

The typical cost to install a window can range from $450 to $650. There are several factors that influence how much it costs, including your property’s location, the number of windows, the materials used in designing the windows, local labor costs, styles and sizes of windows and how energy-efficient the windows are.

Which kind of window is the best?

A window’s energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

What services do window replacement companies do?

Window installers travel to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.

What time of year should I replace my windows?

Though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.

When is it time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
