How Installing Energy-Efficient Windows in East Windsor Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, including:
- Save on electricity 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 home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 206 pounds.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in East Windsor
Windows come in varying purposes, styles and shapes, so costs and services will vary greatly depending on several factors. Below, we describe the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Though the typical cost of replacing one window is about $600, it can range anywhere from $200 to $1,200. These amounts vary depending on specific characteristics of your installation, like material, the location of your home, number of windows, size, type and more.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $319 a year on your energy bills in East Windsor.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you’re not sure which window installation service you should get, your installer should be able to assist you. Generally, 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 East Windsor
The EcoWatch Reviews team differs from other reviewers since we assess these companies through a sustainability lens. We’ve decided to evaluate the best window installers in East Windsor mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the East Windsor area so you can find the best window installation company near you.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, warranty, quality of installation, professionalism, cost 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 considerable investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
East Windsor, NJ Window Replacement FAQs
How much does a window install cost?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually influenced by the size of the window, the location of your property and the type and material 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 kinds of windows?
The most common types of windows for homes are double-hung and single-hung windows, transom windows, casement windows, bay windows, awning windows, slider windows and picture windows.
Do you really have to use a window installation company?
Unless you’re handy and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
How long does window installation usually take?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
