How Installing Energy-Efficient Windows in Stillwater Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Save money on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 206 pounds per year on average.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Stillwater
Let's go over the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
Even though the national average to install one window is around $600, it can range 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 installers also offer door installations and replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation involves replacing a window without taking out the complete frame, which is usually less expensive than a full-frame installation.
Your window installation company can recommend the best type for your project. In Stillwater, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Stillwater
In our search to make your home improvements easier and more eco-friendly in Stillwater, the EcoWatch team landed on the above companies as the best window installation companies in the city. We've evaluated the best window installers in Stillwater mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Stillwater, we only included companies that cover the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Stillwater.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. 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 highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of installation, cost, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points 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 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 a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Stillwater, NJ Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the kinds of windows?
There are several different kinds of windows you can get for your home, including awning windows, casement windows, transom windows, picture windows, bay windows, slider windows and double-hung and single-hung windows.
When do I need to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
How long does window installation take?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How do you know it's time to replace your windows?
Windows usually last about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
