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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way.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.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Waterloo, that’s about 642 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Waterloo

Windows come in different shapes, purposes and styles, so costs and services will vary remarkably depending on your project. Below, we describe the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies depending on several factors, such as the location of your home, material, type, number of windows, size and more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Waterloo homeowners $317+ a year after replacing single-pane windows.

Costs will also vary depending on the material you want for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most 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 step when considering a window installation is to think about whether you want a full-frame or pocket installation.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you should get, your installer can assist you. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Waterloo

EcoWatch reviews are different from other reviews since we’re examining these companies through a sustainability lens. We have evaluated the best window installers in Waterloo mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power 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 Waterloo so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Waterloo, IL Window Replacement FAQs

How much should a window install cost?

The average cost to replace a single window ranges from $450 to $650. There are many factors that affect how much it costs, which include local labor costs, the number of windows, your property’s location, styles and sizes of windows, how energy-efficient the windows are and the materials used in designing the windows.

Which kind of window should I get?

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

Do I really need to use a window installation company?

Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated 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 company is a faster, more efficient and much safer alternative.

How long does window installation typically take?

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