How Installing Energy-Efficient Windows in Buffalo Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Buffalo

Each window replacement company offers various services and has different costs depending on a few factors.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies depending on several factors, such as type, the location of your home, number of windows, size, material and more.

It’s important to remember that windows with the best 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 Buffalo homeowners $511+ a year when replacing single-pane windows.

Something else that affects the total cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your installers will replace the entire window, including the trim, frame and sill. Pocket installations are on the simpler end and won’t carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installation company will be able to help you figure out what’s best for your needs. In Buffalo, the decision will mostly be based on how old your home is and if there’s any moisture damage. Wood can decay if not properly maintained 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 Buffalo

EcoWatch reviews differ from most reviews since we evaluate these companies through a sustainability lens. We’ve decided to evaluate the best window installers in Buffalo mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Buffalo, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Buffalo.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good feedback about their service from a certain company, it won’t be featured on EcoWatch.

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

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

Years of Experience

Lastly, 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.
