How Installing Energy-Efficient Windows in Fair Lawn Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, including:
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 206 pounds.
- 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 your furniture, carpet and other valuables from fading.
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in Fair Lawn
Each window installation company offers varying services and has different price points depending on a few factors.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But prices differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will add extra costs to your project.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with 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 replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the old frame. This means instead of taking out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you decide what’s best for your needs. In Fair Lawn, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Fair Lawn
The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Fair Lawn and ranked them based on the following methodology:
Service Area
Because this is a guide for Fair Lawn, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Fair Lawn.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. 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
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good feedback about their service from a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Fair Lawn, NJ Window Replacement FAQs
How much should window installation cost?
The typical cost to install a single window can range between $450 and $650. There are many factors that influence the price, including how energy-efficient the windows are, styles and sizes of windows, your property’s location, the number 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 are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll get 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 installation companies do?
Window installers will do the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
