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

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save $323 a year on your bills.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 299 pounds.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in New Castle

Each window installation company offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

Although the typical of replacing one window is about $600, it can range from $200 to $1,200. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Asking for free quotes from multiple companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

When considering window replacements, there are typically two kinds that your provider will have: 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 can also involve extra materials, including insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame. This means instead of removing the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which kind of window installation service you need, your installer can help you out. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in New Castle

EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for New Castle, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in New Castle.

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 contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have good things to say about their experience with a certain company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

New Castle, DE Window Replacement FAQs

How much does a window install cost?

The national average cost to install a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What type of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

Window installation professionals travel to your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

How long does it generally take to install windows?

Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.

What time of year is the best time to replace my windows?

Even though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, the weather should be dry, as rain can make the installation harder.
