How Installing Energy-Efficient Windows in Upper Montclair Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- More efficient energy usage in your household: Because the winters can get very cold in Upper Montclair, homeowners usually depend on their heater during that time. Energy-efficient windows lower the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
- 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.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Upper Montclair
Let's take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
On average, Upper Montclair homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. These figures are based on the specifics of your installation, such as material, number of windows, size, the location of your home, type and more.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $283 a year on your energy bills in Upper Montclair.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Upper Montclair, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Upper Montclair
In our hunt to make your home improvements easier and more eco-friendly in Upper Montclair, the EcoWatch team assessed dozens of companies before landing on these. We've decided to evaluate the top window installation companies in Upper Montclair primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower 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 a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, cost, warranty, quality of installation, professionalism and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure 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. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Upper Montclair's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Upper Montclair window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Upper Montclair, NJ Window Replacement FAQs
How much does a window install cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the type and material of the window 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.
Which kind of window is the best?
A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals go to your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How do you know it's time to replace your windows?
Windows typically last about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.
