How Installing Energy-Efficient Windows in Oak Park Saves You Money

When you switch to energy-efficient windows, you may see several perks, such as:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Oak Park

Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you can find from window installers.

How Much Do New Windows Cost?

On average, homeowners in Oak Park can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost is based on several factors, such as number of windows, size, the location of your home, material, type and more.

Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $572 a year on your energy bills in Oak Park.

Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation you should get, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Oak Park

In our search to make your home improvements easier and more eco-friendly in Oak Park, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Oak Park, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Oak Park.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, professionalism, cost, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Oak Park’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Oak Park window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Oak Park, CA Window Replacement FAQs

What is the average cost to install new windows?

The typical cost of replacing a single window can range between $450 and $650. There are several factors that influence how much it costs, including the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property’s location, the number of windows and styles and sizes of windows.

What are the different kinds of windows?

The most common kinds of windows for homes include: double-hung and single-hung windows, picture windows, slider windows, bay windows, awning windows, transom windows and casement windows.

Do you really have to use a window installation company?

You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best left to the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure 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 more important than the temperature is that the weather should be dry.
