How Installing Energy-Efficient Windows in Newark Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• Protect your valuables from fading: When you upgrade 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.
• Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 299 pounds.

Estimated Cost of Window Replacement in Newark

Windows come in all shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

On average, Newark homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost is based on several factors, such as the location of your home, number of windows, size, type, material and more.

It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Newark home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a window replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

Your window replacement company should be able to help you decide what’s best for your needs. In Newark, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly 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 Newark

EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. We’ve assessed the best window installers in Newark mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Newark area so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have good things to say about their service from a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide 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.

Years of Experience

Due to Newark’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Newark window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
