How Installing Energy-Efficient Windows in Newark Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to make the switch:
- Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 property if you decide to sell.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
Estimated Cost of Window Replacement in Newark
When researching window installation, each company offers varying services and prices. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
Although the average cost to install one window is around $600, it can range from $200 to $1,200. This is due to the fact that the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Newark.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid 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 kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the complete window, including the trim, frame and sill. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole window 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 can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Newark
In our hunt to find the most reliable, eco-friendly window installers in Newark, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We’ve reviewed the top window installation companies in Newark mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Newark, we paid more attention to companies that serve 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 Newark.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. 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
Customer feedback is another very important review factor. If the majority of customers don’t have nice things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, 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 provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
