How Installing Energy-Efficient Windows in Glen Rock Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save money on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: In Glen Rock, you can reduce your indirect greenhouse gas emissions by about 206 pounds per year when you install energy-efficient windows.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in Glen Rock
Each window replacement company offers various services and has varying price points based on several factors.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, such as number of windows, the location of your home, material, type, size and more.
It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Glen Rock homeowners $285+ a year when replacing single-pane windows.
Requesting free quotes from multiple providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
When it comes to window installations, there are typically two types that your installer will offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the old frame. So, instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company will be able to help you choose what’s best for your needs. In Glen Rock, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Glen Rock
The EcoWatch Reviews team differs from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Glen Rock and assigned rankings based on 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 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 included on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of installation, professionalism, warranty, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious 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
Due to Glen Rock’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Glen Rock window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Glen Rock, NJ Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost of installing a single window can range from $450 to $650. There are a variety of factors that influence the price, including the materials used in designing the windows, styles and sizes of windows, the number of windows, how energy-efficient the windows are, local labor costs and your property’s location.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products manufactured 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 once?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
How long does window installation typically take?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
