How Installing Energy-Efficient Windows in North Wantagh Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: In North Wantagh, you can reduce your indirect greenhouse gas emissions by about 307 pounds per year when you upgrade to energy-efficient windows.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in North Wantagh

Getting free quotes from several companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails installing a new window within the old frame. This means instead of taking out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in North Wantagh

The EcoWatch Reviews team is different from most reviewers because we assess these companies through a sustainability lens. We’ve decided to evaluate the best window installation companies in North Wantagh mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for North Wantagh, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in North Wantagh.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of North Wantagh’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of North Wantagh window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
