How Installing Energy-Efficient Windows in Buffalo Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: In Buffalo, you can cut your indirect greenhouse gas emissions by about 65 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Buffalo
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, Buffalo homeowners can expect their window installations to range from $250 to $1,200. The average cost is at about $600. These figures vary based on the specifics of your installation, including the location of your home, material, type, number of windows, size and more.
It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Buffalo homeowners $368+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are completely 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 regard to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Buffalo
EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Buffalo, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Buffalo.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Buffalo’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Buffalo window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Buffalo, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
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 often the most energy-efficient since they are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation company whenever you need to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best left to the professionals.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all the windows together is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or leaky, you can replace just those.
How long does it typically take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
