How Installing Energy-Efficient Windows in Cortlandt Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Decrease your carbon footprint: In Cortlandt, you can reduce your indirect greenhouse gas emissions by about 154 pounds per year when you install energy-efficient windows.
- Save on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Cortlandt
When looking into window installation, each company offers different services and prices. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Generally, homeowners in Cortlandt can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. These figures vary depending on the specifics of your installation, including type, material, the location of your home, number of windows, size and more.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Cortlandt homeowners $331+ per year after replacing single-pane windows.
We recommend getting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step of a window installation is to figure out whether you want a full-frame or pocket installation.
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler 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.
If you're still debating which kind of installation you should get, you can talk to your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Cortlandt
In our search to find the most reliable, eco-friendly window installers in Cortlandt, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Cortlandt and ranked them based on the following methodology:
Service Area
Because this is a guide for Cortlandt, we only included companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Cortlandt.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type 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
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, warranty, quality of parts, cost, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Cortlandt, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to replace one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don't have the time or experience, we recommend hiring a professional.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
