How Installing Energy-Efficient Windows in Ithaca Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Save on energy bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $241 annually on your energy bills in Ithaca.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Ithaca
When considering window installation, each company offers different services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Although the typical to replace a single window is about $600, it can range anywhere from $200 to $1,200. But costs differ considerably 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 will make your project cost more.
It's important to remember that windows with higher 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 $241+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are solid 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?
The first step when considering an installation is to clarify whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Ithaca
The EcoWatch Reviews team is different from other reviewers since we look at these companies through a sustainability lens. We have evaluated the top window installers in Ithaca mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty 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
When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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
Customer feedback is another super important review factor. If most customers don't have positive things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers may not provide the most quality service. On the other hand, we want to make sure 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 that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Ithaca's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Ithaca window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Ithaca, NY Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost of replacing a single window can range between $450 and $650. There are a variety of factors that affect how much it costs, which include local labor costs, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, your property's location and the number of windows.
What are the different kinds of windows?
There are various types of windows you can get for your home, such as casement windows, bay windows, slider windows, double-hung and single-hung windows, picture windows, transom windows and awning windows.
What services do window replacement companies do?
Window installation professionals travel to your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
