Marengo Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Marengo, IL 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 Marengo Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to consider making the switch:

  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
  • More efficient energy usage in your household: Because the winters can get very cold in Marengo, homeowners often depend on their heater during that time. Energy-efficient windows lower the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Protect your valuables: Many Energy Star certified 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 Marengo

Let's go over the cost of window installation and the types of services you may need for your home.

How Much Do New Windows Cost?

According to our market research, the typical cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. These numbers are based on the specifics of your installation, such as type, material, the location of your home, number of windows, size and more.

It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Marengo homeowners $317+ a year when replacing single-pane windows.

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 easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with 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?

The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing 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 unsure which type of window installation service you need, your installer can advise you. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Marengo

EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We have evaluated the top window installers in Marengo mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Marengo, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Marengo.

Work Quality

We're willing to bet that you're looking for professionals who 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 received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If most customers don't have positive things to say about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try 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. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Marengo, IL Window Replacement FAQs

How much does window installation cost?

The average cost to install one window can range between $450 and $650. There are several factors that influence the cost, including how energy-efficient the windows are, your property's location, local labor costs, the materials used in designing the windows, the number of windows and styles and sizes of windows.

What are the different types of windows?

There are various types of windows you can get for your home, such as casement windows, picture windows, bay windows, awning windows, double-hung and single-hung windows, transom windows and slider windows.

When do I have to use a window installation company?

Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
