How Installing Energy-Efficient Windows in New Hanover Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in New Hanover

When considering window installation, each company provides varying services and costs. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Although the average cost to install one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, such as number of windows, the location of your home, size, type, material and more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $312 a year on your energy bills in New Hanover.

Getting free quotes from several companies is the best way to find out which one will work best for your budget.

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 replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without removing the entire frame, which tends to be cheaper than a full-frame installation.

If you’re still debating which kind of installation you should get, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in New Hanover

EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. We have evaluated the best window installation companies in New Hanover primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve New Hanover so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, cost, warranty, professionalism, quality of installation and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave 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. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

New Hanover, PA Window Replacement FAQs

How much does window installation cost?

The typical cost to replace one window ranges between $450 and $650. There are a variety of factors that affect the price, including the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are, your property’s location and the number of windows.

What type of window is the most energy-efficient?

A window’s energy efficiency is affected by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installers do?

Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

How do you know it’s time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on your energy bills, replacing all of your windows at once is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
