How Installing Energy-Efficient Windows in Buffalo Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, such as:

  • Better temperature control in your home: When you live in a place like Buffalo where the summers can be pretty warm, you usually have 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.
  • 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 65 pounds per year on average.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Buffalo

When considering window installation, each company provides varying services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. 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 companies also provide door replacements, which carry a higher price tag.

Whether or not you want 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 $368 a year on your energy bills in Buffalo.

Something else that influences the overall cost is the material of the frame you choose. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most 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?

When it comes to window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your professionals will replace the entire window, including the trim, frame and sill. A pocket installation means replacing a window without taking out the entire frame, which is generally less expensive than a full-frame installation.

Your window installation company will be able to help you decide what's best for your needs. In Buffalo, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Buffalo

The EcoWatch Reviews team is different from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Buffalo, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Buffalo.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their experience with a certain installer, you won't see it featured on EcoWatch.

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 scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Buffalo, NY Window Replacement FAQs

How much does window installation cost?

The average cost to replace a window ranges between $450 and $650. There are several factors that influence the cost, including the materials used in designing the windows, styles and sizes of windows, the number of windows, your property's location, local labor costs and how energy-efficient the windows are.

What are the most common types of replacement windows?

There are various kinds of windows you can get for your home, such as bay windows, casement windows, double-hung and single-hung windows, slider windows, picture windows, transom windows and awning windows.

What services do window replacement companies provide?

Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.

How long does it take to install windows?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.

What time of year is the best time to replace my windows?

Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
