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

By switching to energy-efficient windows, you can enjoy several benefits, such as:

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save some money on your bills.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in New Castle

Let's go over the cost of window replacement and the kinds of services you may need for your home.

How Much Do New Windows Cost?

According to our research, the typical cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. These estimates vary depending on specific characteristics of your installation, including type, size, the location of your home, material, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save New Castle homeowners $301+ each year after replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are typically two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company will be able to help you figure out what's best for your needs. In New Castle, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in New Castle

In our search to make your home improvements easier and more eco-friendly in New Castle, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency 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

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, cost, professionalism, quality of parts, warranty and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, 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 provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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