How Installing Energy-Efficient Windows in Waterloo Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save money on power bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $317 annually on your energy bills in Waterloo.
  • Decrease your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Waterloo

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

How Much Do New Windows Cost?

Typically, Waterloo homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at around $600. How much it will cost varies based on several factors, like the location of your home, material, number of windows, size, type and more.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide 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 cost the most and are the most in-demand. They’re also aesthetically pleasing and provide 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?

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In Waterloo, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Waterloo

EcoWatch is different from other reviewers, as we assess these companies through a sustainability lens. We’ve evaluated the top window installation companies in Waterloo primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Waterloo so you can find the best window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a hefty 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

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

Waterloo, IL Window Replacement FAQs

What is the typical cost to install windows in a home?

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

What kind of window is the best for energy efficiency?

A window’s energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

You should hire a window installation professional whenever you want to upgrade your windows. Installing windows is a involved process that can take a lot of time, so it’s best left to the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. No matter 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.

How long does it usually take to install windows?

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