How Installing Energy-Efficient Windows in Stony Brook University Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Stony Brook University
Windows come in different purposes, shapes and styles, so costs and services will vary greatly depending on several factors. Below, we go over the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Typically, homeowners in Stony Brook University can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates vary depending on the specifics of your installation, including size, number of windows, type, material, the location of your home and more.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, 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 Stony Brook University homeowners $215+ each year after replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Because full-frame installations are more involved, they will raise the overall cost. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Stony Brook University, the decision will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Stony Brook University
EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. We have evaluated the top window replacement companies in Stony Brook University mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Stony Brook University so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and variety 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a 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 Stony Brook University's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Stony Brook University window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Stony Brook University, NY Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
The most common kinds of windows for homes include: picture windows, double-hung and single-hung windows, bay windows, awning windows, transom windows, casement windows and slider windows.
Can I install my own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How do you know it's time to replace your windows?
Windows usually last 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to see a noticeable difference. However, if you have only one or two windows that are damaged or leaky, you can replace just those.
