How Installing Energy-Efficient Windows in Stillwater Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
- More efficient energy usage in your household: Because the winters can get cold in Stillwater, homeowners usually depend on their heater during that time. Energy-efficient windows cut back on the amount of heat that is lost through your windows, making it easier to keep your home warm.
- Better temperature control in your home: When you live in a place like Stillwater where the summers can get pretty warm, you usually need to rely on your air conditioner to keep your house cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
Estimated Cost of Window Replacement in Stillwater
Let's go over the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Although the national average of replacing one window is about $600, it can range from $200 to $1,200. How much it will cost you depends on several factors, like size, the location of your home, material, type, number of windows and more.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Stillwater homeowners $386+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations require 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 deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window replacement company will be able to help you decide what's best for your needs. In Stillwater, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Stillwater
In our search to find the most reliable, eco-friendly window installers in Stillwater, the EcoWatch team assessed many companies before deciding on these. We've decided to evaluate the best window installation companies in Stillwater mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity 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 installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. 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, quality of parts, warranty, quality of installation, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is protected. 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 good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Stillwater, NY Window Replacement FAQs
What is the average cost to install 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 typically influenced by 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 initially but can save you a decent amount of money a year in energy bills.
What are the types of windows?
There are several different types of windows you can get for your home, including slider windows, transom windows, awning windows, picture windows, bay windows, double-hung and single-hung windows and casement windows.
Can I replace my own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window installation company 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 the same time?
If you want to get more efficient windows and save money on energy costs, replacing all your windows together is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
