How Installing Energy-Efficient Windows in Princeton Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Princeton, that’s about 206 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Princeton
Each window installation company provides varying services and has varying price points depending on several factors.
How Much Do New Windows Cost?
According to our market research, the national average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. But costs will vary considerably based on the quality of your products, the current condition of your home, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
It’s also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Princeton home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the frame that’s already there. This means instead of tearing out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which window installation service you need, your installer should be able to advise you. In general, the choice is based on 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 Princeton
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. We have decided to review the best window installation companies in Princeton primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Princeton, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Princeton.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain installer, it won’t be featured on EcoWatch.
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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Princeton’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Princeton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Princeton, NJ Window Replacement FAQs
How much should a window install cost?
The average cost to install one window can range from $450 to $650. There are many factors that influence the price, such as how energy-efficient the windows are, your property’s location, the number of windows, styles and sizes of windows, local labor costs and the materials used in designing the windows.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to see a noticeable difference. However, if you have only a few windows that are broken or drafty, you can replace just those.
How long does it generally take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during an 8-hour work day.
