Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. Potential leaks or drafts from your windows can make your AC or heater work extra hard in the summer or winter.

That's also bad for the environment, as the extra energy used by outdated windows increases your carbon footprint.

Because windows are so important for your home, picking the best company for you is a big decision to make. That's why the EcoWatch team has made this list of the top window replacement companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Morristown Saves You Money

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

  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
  • Better temperature control in your home: Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Morristown

Let's go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the typical cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. This is due to the fact that the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Morristown home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full 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 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. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can advise you on the best type for your project. In Morristown, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Morristown

In our hunt to make your home improvements easier and more eco-friendly in Morristown, the EcoWatch Reviews team assessed many companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

Since this is a guide for Morristown, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Morristown.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks 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 customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, warranty, cost, professionalism, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, 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 labor rank higher with EcoWatch.

Years of Experience

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

Morristown, NJ Window Replacement FAQs

How much does a window install cost?

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

Which kind of window is the best?

A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installers do?

Window installation companies cover the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.

How often should you replace your windows?

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