How Installing Energy-Efficient Windows in Rockford Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 449 pounds per year on average.
  • Save money on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save about $318 annually on your energy bills in Rockford.

Estimated Cost of Window Replacement in Rockford

Windows come in varying styles, purposes and shapes, so costs and services will differ considerably based on your project. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

On average, Rockford homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. How much it will cost varies depending on several factors, including number of windows, the location of your home, material, size, type and more.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $318 a year on your energy bills in Rockford.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When considering window installations, there are generally two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Rockford

EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Rockford, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Rockford.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, cost, quality of installation, professionalism, warranty and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Rockford, IL Window Replacement FAQs

What is the average cost to replace windows?

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

What are the most common types of replacement windows?

The most common kinds of windows for homes include: awning windows, picture windows, casement windows, bay windows, double-hung and single-hung windows, slider windows and transom windows.

What services do window installation companies offer?

Window installation professionals visit your home to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.

How long does window installation take?

Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on energy costs, replacing all of your windows together is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
