How Installing Energy-Efficient Windows in Rockford Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could help you:

  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Rockford

Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Generally, Rockford homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. Costs will vary significantly based on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that switching out the windows on your Rockford home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We advise requesting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

Your window installation company will be able to help you decide what’s best for your needs. In Rockford, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Rockford

EcoWatch reviews are different from other reviews, as we assess these companies through a sustainability lens. We’ve decided to review the top window installation companies in Rockford mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

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

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Rockford’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Rockford window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Rockford, IL Window Replacement FAQs

How much does a window install cost?

The average cost to install one window ranges between $450 and $650. There are several factors that influence how much it costs, such as your property’s location, styles and sizes of windows, the number of windows, the materials used in designing the windows, local labor costs and how energy-efficient the windows are.

Which type of window is the best?

A window’s energy efficiency depends on a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What services do window installation companies provide?

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

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.

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 probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
