How Installing Energy-Efficient Windows in Alsip Saves You Money

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

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Alsip

Let's go over the cost of updating your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Even though the typical to replace a single window is around $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Alsip homeowners $269+ a year when replacing single-pane windows.

Getting free quotes from several companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable rot. Full-frame installations are more involved and will raise the total cost. A pocket installation entails replacing a window without removing the whole frame, which is generally cheaper than a full-frame installation.

If you're still debating which type of installation you need, you can ask your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Alsip

In our search to find the most reliable, eco-friendly window installers in Alsip, EcoWatch examined many companies before settling on these. We've decided to review the top window replacement companies in Alsip mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When choosing 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 consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback 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 reflects the quality of services across nearly every category, including cost, quality of parts, quality of installation, professionalism, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Because of Alsip's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Alsip window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Alsip, IL Window Replacement FAQs

How much does window installation cost?

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

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. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Do you really need to use a window installation company?

Unless you have experience with home improvement projects and have all the tools you need 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 one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.

What time of year should I replace my windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
