How Installing Energy-Efficient Windows in Rockford Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, including:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
  • Decrease your carbon footprint: In Rockford, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year when you install energy-efficient windows.

Estimated Cost of Window Replacement in Rockford

Windows come in different purposes, styles and shapes, so costs and services will vary greatly based on several factors. Below, we detail the typical cost and services that you'll find from window installation companies.

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 $271 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.

Which type of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

Do you really have to use a window installation company?

Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer option.

How long does it usually take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.

Should I replace my windows all at the same time?

If you want to get more efficient windows and save money on energy costs, replacing all the windows at once is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
