How Installing Energy-Efficient Windows in University City Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could help you:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In University City, that's about 763 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in University City
When considering window installation, each company provides different services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost you varies based on several factors, like type, the location of your home, size, material, number of windows and more.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your University City 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 varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with 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 offer decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In University City, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in University City
In our search to find the most reliable, eco-friendly window installers in University City, the EcoWatch team chose the above companies as the best window installation companies in the city. We have decided to review the top window installation companies in University City mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for University City, we only included companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in University City.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, warranty, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to University City's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of University City window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
University City, MO Window Replacement FAQs

There are various kinds of windows you can get for your home, such as casement windows, transom windows, double-hung and single-hung windows, slider windows, bay windows, picture windows and awning windows.
Do you really have to use a window installation company?
You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
How long does it generally take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
