How Installing Energy-Efficient Windows in Leavenworth Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, such as:
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 583 pounds per year on average.
Estimated Cost of Window Replacement in Leavenworth
When considering window installation, each company provides varying services and prices. Let’s go over some average costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These amounts vary depending on the specifics of your installation, like number of windows, type, size, material, the location of your home and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Leavenworth homeowners $474+ a year after replacing single-pane windows.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more 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 still trying to decide which type of installation you need, you can consult with your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Leavenworth
EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. We’ve decided to assess the best window installers in Leavenworth primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified 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
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, 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. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Leavenworth, KS 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 generally dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
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 often the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
