Oak Park Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Oak Park, CA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

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  • Protect your investment: When you have an older home, your windows could also be outdated or leaky.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 expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is because of the fact that window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

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

Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the complete window, including the frame, trim and sill. Pocket installations are simpler and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Oak Park

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

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain company, it won’t be featured on EcoWatch.

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 providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

Because of 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 typical cost to replace windows in a home?

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

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 need 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 take a lot of time, so it’s best left to the professionals.

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 make sure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.

How long does window installation usually take?

Since the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.
