How Installing Energy-Efficient Windows in West Milford Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- More efficient energy usage in your home: In West Milford where the winters can be very cold, energy-efficient windows cut back on the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save some money on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in West Milford
Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in West Milford can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These numbers vary depending on the specifics of your installation, including material, type, number of windows, the location of your home, size and more.
It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your West Milford home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a window replacement is to clarify whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the entire 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 comprehensive and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company can recommend the best type for your project. In West Milford, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in West Milford
In our search to find the most reliable, eco-friendly window installers in West Milford, the EcoWatch team chose the above companies as the top window installation companies in the city. We have evaluated the best window installers in West Milford mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the West Milford area so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has received 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 feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most 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
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
West Milford, NJ Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of installing one window is about $600 but can range between $200 and $1,200, based on several factors. The price is typically dependent on 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 hundreds of dollars a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
