How Installing Energy-Efficient Windows in Justice Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
  • Reduce your carbon footprint: In Justice, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year after you switch to energy-efficient windows.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save more on your bills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Justice

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from window installers.

How Much Do New Windows Cost?

Generally, Justice homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at about $600. How much it will cost varies depending on several factors, such as type, size, number of windows, the location of your home, material and more.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Justice homeowners $295+ per year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although 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?

The first step of a window replacement is to think about whether you want a full-frame or pocket installation.

Full-frame installations entail replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has significant damage. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Justice

In our search to make your home improvements easier and more eco-friendly in Justice, the EcoWatch team chose the above companies as the best window installation companies in the city. We've reviewed the top window installers in Justice mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Justice so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of installation, cost, quality of parts, professionalism and more.

Cost

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

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Justice, IL Window Replacement FAQs

What is the typical cost to install windows?

The typical cost of installing a window can range between $450 and $650. There are a variety of factors that affect the cost, which include the number of windows, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs and your property's location.

Which kind of window should I get?

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. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installation professionals cover the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.

How often should you replace windows?

Windows have an average 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.
