How Installing Energy-Efficient Windows in Ithaca Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Save on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Ithaca

When researching window installation, each company provides varying services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. These figures vary based on specific characteristics of your installation, including material, type, size, the location of your home, number of windows and more.

It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Ithaca homeowners $402+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the full window, including the frame, trim and sill. A pocket installation involves replacing a window within the existing frame. This means instead of tearing out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Ithaca

EcoWatch reviews differ from other reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Ithaca area so you can find the right window installation company near you.

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 installer included on this list to make sure its technicians are well-qualified and that the company has gotten tons 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 positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure that investment is protected. Window installation companies that give you 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 a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
