How Installing Energy-Efficient Windows in Libertyville Saves You Money

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

  • Better temperature control in your home: When you live in a city like Libertyville where the winters can be very cold, you often have to rely on your heater to keep your home warm. Energy-efficient windows can decrease the amount of heat lost through your windows when heating your home.
  • Save on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date 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 because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Libertyville

Windows come in varying shapes, purposes and styles, so costs and services will differ greatly depending on your project. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. But costs will vary significantly based on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $298 a year on your energy bills in Libertyville.

Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Libertyville, the choice will mostly depend on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Libertyville

In our hunt to find the most reliable, eco-friendly window installers in Libertyville, the EcoWatch team examined dozens of companies before landing on these. Along with energy efficiency, we evaluated several window installers in Libertyville and assigned rankings using the following methodology:

Service Area

Since this is a guide for Libertyville, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Libertyville.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer included in our guide to ensure 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 patterns 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 indicates the quality of services across nearly every category, including warranty, quality of parts, quality of installation, cost, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave 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 have lengthy warranties for products, parts and labor 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 will earn higher rankings by our standards. We like to see at least ten years of experience.

Libertyville, IL Window Replacement FAQs

What is the typical cost to install windows?

The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

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

Can I replace my own windows?

If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don't have the time or know-how, we recommend hiring a professional.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
