How Installing Energy-Efficient Windows in Mount Sinai Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Mount Sinai, that’s about 307 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $215 annually on your energy bills in Mount Sinai.
Estimated Cost of Window Replacement in Mount Sinai
Each window installer offers various services and has different price points based on several factors.
How Much Do New Windows Cost?
Generally, homeowners in Mount Sinai can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. 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 installers also offer door replacements, which will add extra costs to your project.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Mount Sinai homeowners $215+ each year after replacing single-pane windows.
We advise requesting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you’re not sure which window installation service you should get, your installer can advise you. Typically, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Mount Sinai
EcoWatch reviews differ from most 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 using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, cost, quality of installation, quality of parts, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Mount Sinai’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Mount Sinai window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mount Sinai, NY Window Replacement FAQs
How much does a window install cost?
The typical cost of installing a window can range between $450 and $650. There are a variety of factors that affect the cost, such as your property’s location, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs and the number of windows.
What kind of window is the best for energy efficiency?
A window’s energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I replace my own windows?
While it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at the same time is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
How long does window installation generally take?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
