How Installing Energy-Efficient Windows in Buffalo Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Buffalo, that's about 286 pounds per year on average.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
Estimated Cost of Window Replacement in Buffalo
Windows come in various shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Although the national average to install one window is about $600, it can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $314 a year on your energy bills in Buffalo.
Requesting free quotes from multiple installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step of an installation is to figure out whether you need a full-frame or pocket installation.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant damage. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window replacement company will be able to help you figure out what's best for your needs. In Buffalo, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Buffalo
EcoWatch reviews are different from other reviews because we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Buffalo, we only included companies that provide services to the city. There are other reputable providers that didn't make our list 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 of window you get. 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 online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, quality of installation, warranty, cost, professionalism and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Buffalo's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Buffalo window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Buffalo, PA Window Replacement FAQs
What is the average cost to install windows?
The typical cost to install a window ranges between $450 and $650. There are a variety of factors that affect the price, such as the materials used in designing the windows, the number of windows, how energy-efficient the windows are, styles and sizes of windows, your property's location and local labor costs.
What kind of window is the most energy-efficient?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installation companies cover the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, because rain can make the installation harder.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
