How Installing Energy-Efficient Windows in Northwest Harbor Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:
- Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
Estimated Cost of Window Replacement in Northwest Harbor
Let's take a look at the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Generally, Northwest Harbor homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which have a higher price tag.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Asking for free quotes from multiple providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has significant deterioration. Full-frame installations are more involved and will raise the total cost. A pocket installation involves replacing a window within the existing frame. So, instead of tearing out the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Northwest Harbor
In our search to make your home improvements easier and more eco-friendly in Northwest Harbor, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed 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 Northwest Harbor so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. 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 patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, cost, warranty, quality of installation, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies with 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.
Northwest Harbor, NY Window Replacement FAQs
How much does a window install cost?
The average cost of replacing a window ranges from $450 to $650. There are many factors that affect how much it costs, which include your property's location, the number of windows, styles and sizes of windows, the materials used in designing the windows, local labor costs and how energy-efficient the windows are.
What type of window is the best for energy efficiency?
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. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that need to be installed.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.
