How Installing Energy-Efficient Windows in Rockford Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • More efficient energy usage in your home: In Rockford where the winters can get very cold, energy-efficient windows lower the amount of heat that is lost through your windows, which makes it easier to keep your house warm.

Estimated Cost of Window Replacement in Rockford

Let's go over the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost varies depending on several factors, such as the location of your home, size, type, number of windows, material and more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Rockford homeowners $318+ each year after replacing single-pane windows.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, though 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?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot or deterioration. Full-frame installations are more involved and will raise the overall cost. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can advise you on the best type for your project. In Rockford, the choice will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Rockford

In our search to find the most reliable, eco-friendly window installers in Rockford, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Rockford, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make our list 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 company included in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Rockford's climate, homeowners need to be wary of rot, water damage and low efficiency. 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 should window installation cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

There are various kinds of windows you can get for your home, such as transom windows, double-hung and single-hung windows, casement windows, bay windows, slider windows, picture windows and awning windows.

What services do window replacement companies provide?

Window installation companies cover the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.

How long does window installation generally take?

Each window takes around 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
