How Installing Energy-Efficient Windows in New Ulm Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in New Ulm
Windows come in various shapes, purposes and styles, so costs and services will differ remarkably based on several factors. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Even though the average cost of replacing a single window is around $600, it can range from $200 to $1,200. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save New Ulm homeowners $477+ a year when replacing single-pane windows.
We advise requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the total window, including the trim, sill and frame. A pocket installation means replacing a window without removing the entire frame, which tends to be less expensive than a full-frame installation.
If you’re unsure which type of window installation service you need, your installer should be able to advise you. Typically, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in New Ulm
EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We’ve reviewed the top window installers in New Ulm mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce 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 the New Ulm area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of parts, professionalism, cost, quality of installation and more.
Cost
Cheaper windows certainly don’t 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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
New Ulm, MN Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is often dependent on 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 upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
A window’s energy efficiency is influenced 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 often the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is a good time to replace my windows?
Though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
How long does window installation typically take?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
