How Installing Energy-Efficient Windows in Green Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Better temperature control in your home: Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
- 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. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Green
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, Green homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. Costs will differ considerably based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.
Whether or not you want energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $289 a year on your energy bills in Green.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company will be able to help you understand what's best for your needs. In Green, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Green
In our hunt to make your home improvements easier and more eco-friendly in Green, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Green and ranked them based on the following methodology:
Service Area
Since this is a guide for Green, we only included companies that cover the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Green.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers higher marks 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 determine the companies with the most customer satisfaction, weighted by sample size. 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
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Green's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Green window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Green, NJ Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
There are various kinds of windows you can get for your house, such as bay windows, awning windows, casement windows, double-hung and single-hung windows, slider windows, picture windows and transom windows.
Do I really need to use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all of your 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 damaged or drafty, you can replace just those.
