Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's efficiency can also have a large impact on home energy conservation. During the cold winter months, the last thing you want is your heat to leak out of your outdated, drafty windows.
That's also bad for the environment, as the extra energy required by drafty windows increases your carbon footprint.
Efficient windows are particularly important in Lockport, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $335 each year.

How Installing Energy-Efficient Windows in Lockport Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to make the switch:
- 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save money on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Lockport
When researching window installation, each company offers varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
On average, Lockport homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But prices vary remarkably depending 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, which have a higher price tag.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Lockport homeowners $335+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has significant damage. Because full-frame installations are more involved, they will increase the total cost. Pocket installations are on the simpler end and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to help you understand what's best for your needs. In Lockport, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Lockport
EcoWatch reviews are different from most reviews, as we look at these companies through a sustainability lens. We've reviewed the best window replacement companies in Lockport primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient 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
Since this is a guide for Lockport, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Lockport.
Work Quality
When selecting 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 opt for. 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. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, professionalism, warranty, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, 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.
Lockport, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors.

Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
A window's energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a involved process that can take a lot of time, so it's best handled by the professionals.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation more difficult.
When is it time to replace your windows?
Windows typically last about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them looked at by an expert to see if they need any repairs or replacements.
