How Installing Energy-Efficient Windows in West Milford Saves You Money

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

  • 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In West Milford, that’s about 73 pounds per year on average.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up 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 West Milford

Each window installation company provides various services and has different price points based on several factors.

How Much Do New Windows Cost?

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

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save West Milford homeowners $288+ each year after replacing single-pane windows.

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

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re unsure which kind of window installation service you should get, your installer should be able to advise you. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in West Milford

In our hunt to find the most reliable, eco-friendly window installers in West Milford, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed several window installers in West Milford and assigned rankings using the following methodology:

Service Area

Because this is a guide for West Milford, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in West Milford.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand 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 find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, warranty, cost, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

West Milford, NJ Window Replacement FAQs

How much does window installation cost?

The national average cost to replace a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the different types of windows?

There are several different kinds of windows you can get for your home, such as casement windows, double-hung and single-hung windows, transom windows, picture windows, bay windows, slider windows and awning windows.

Can you replace your own windows?

Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, it shouldn’t be raining, since rain can make the installation more difficult.

How long does it take to install windows?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
