How Installing Energy-Efficient Windows in South Plainfield Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, including:

• Save on power bills: After you install 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 house.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in South Plainfield

Let’s go over the cost of updating your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Although the average cost of replacing one window is about $600, it can range from $200 to $1,200. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which have a higher price tag.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save South Plainfield homeowners $306+ a year when replacing single-pane windows.

Requesting free quotes from multiple installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the whole window, including the sill, trim and frame. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re unsure which type of window installation service you need, your installer can help you out. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

EcoWatch reviews are different from other reviews since we’re examining these companies through a sustainability lens. We have evaluated the best window installation companies in South Plainfield mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your electricity 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 South Plainfield, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in South Plainfield.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
