How Installing Energy-Efficient Windows in Denville Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Denville, that's about 206 pounds per year on average.
  • Save money on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $287 annually on your energy bills in Denville.

Estimated Cost of Window Replacement in Denville

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

How Much Do New Windows Cost?

Although the average of installing one window is about $600, it can range from $200 to $1,200. How much it will cost you varies depending on several factors, like the location of your home, number of windows, type, size, material and more.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, 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 Denville homeowners $287+ each year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve 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 a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're not sure which window installation service you should get, your installer should be able to help you out. In general, the decision 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 Denville

In our hunt to make your home improvements easier and more eco-friendly in Denville, EcoWatch examined dozens of companies before landing on these. We have evaluated the best window replacement companies in Denville primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Denville, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Denville.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, warranty, professionalism, quality of installation, cost and more.

Cost

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

Warranty

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

Years of Experience

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

Denville, NJ Window Replacement FAQs

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

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

What kind of window is the best for energy efficiency?

A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

You should use a window installation professional whenever you need new windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.

How long does window installation generally take?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.

How often do you need to replace your windows?

Windows typically have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they need any repairs or replacements.
