How Installing Energy-Efficient Windows in Waterloo Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to think about making the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
- 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.
Estimated Cost of Window Replacement in Waterloo
Each window installer provides varying services and has different costs depending on a few factors.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will make your project cost more.
It's also worth noting that energy-efficient windows will typically cost more initially, but Energy Star predicts that switching out the windows on your Waterloo home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step of an installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation means replacing a window without taking out the entire frame, which is usually cheaper than a full-frame installation.
Your window replacement company will be able to help you choose what's best for your needs. In Waterloo, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Waterloo
EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best 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 insulation and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say 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 would like 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
Protecting your investment in new windows is important. For that reason, window installation companies that have 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 water damage, low efficiency and rot. 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 average cost to install new windows in a home?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installation professionals go to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, it shouldn't be raining, since rain can make the installation harder.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
