Why you can trust EcoWatch
A review of the top window replacement companies in Quincy may not seem like the most riveting article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could be responsible for about 30% of residential energy climate costs. In Quincy, where the energy bills are an average of $35 per month, that's almost $$126 per year wasted.
That's also bad news for the environment because the extra energy used by leaky windows increases your carbon footprint.
So if you're building a new home, renovating or replacing your windows in Quincy, this is the best place to get started.

How Installing Energy-Efficient Windows in Quincy Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to make the switch:
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save $327 a year on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- More efficient energy usage in your household: In Quincy where the winters can be very cold, energy-efficient windows reduce how much heat is lost through your windows, which makes it easier to keep your house warm.
Estimated Cost of Window Replacement in Quincy
Windows come in various shapes, styles and purposes, so costs and services will vary tremendously based on several factors. Below, we describe the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Quincy home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you pick 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 using 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're still trying to decide which kind of installation to get, you can consult with your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Quincy
EcoWatch is different from most reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using 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
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, warranty, quality of parts, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers 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.
Quincy, IL Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is often dependent on 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 hundreds of dollars a year in energy bills.
What are the different types of windows?
The most common types of windows for homes are casement windows, double-hung and single-hung windows, picture windows, awning windows, slider windows, transom windows and bay windows.
Can you install your own windows?
While you can install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
Should I replace all my windows at once?
If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
