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

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

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • 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.
  • Better temperature control in your home: Residing in a very cold place like New Castle often means relying on your heater to keep your house cool. Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in New Castle

Windows come in varying shapes, styles and purposes, so costs and services will differ remarkably depending on several factors. Below, we describe the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. But costs will differ considerably depending on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save New Castle homeowners $301+ each year after replacing single-pane windows.

Asking for free quotes from multiple installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're not sure which kind of window installation service you need, your installer can advise you. Generally, the choice 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

In our hunt to find the most reliable, eco-friendly window installers in New Castle, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we evaluated 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 the New Castle area so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good things to say about their service from 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 as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, 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

What is the typical cost to install windows in a home?

The average cost to install a single window ranges between $450 and $650. There are many factors that affect how much it costs, including the materials used in designing the windows, the number of windows, styles and sizes of windows, how energy-efficient the windows are, your property's location and local labor costs.

What are the different types of windows?

The most common kinds of windows for homes are slider windows, double-hung and single-hung windows, picture windows, transom windows, awning windows, casement windows and bay windows.

Do I really need to use a window installation company?

You should hire a window installation professional whenever you want new windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, it shouldn't be raining, since rain can make the installation more difficult.
