How Installing Energy-Efficient Windows in Montclair Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
- 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.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Montclair, that's about 117 pounds per year on average.
Estimated Cost of Window Replacement in Montclair
Let's take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. These amounts vary depending on specific characteristics of your installation, such as material, size, the location of your home, type, number of windows and more.
It's important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Montclair homeowners $540+ a year when replacing single-pane windows.
Asking for free quotes from multiple companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations require replacing the full 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 time-consuming and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company will be able to help you figure out what's best for your needs. In Montclair, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Montclair
EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Montclair and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Montclair, we only included companies that serve the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Montclair.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, professionalism, quality of installation, quality of parts, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a variety 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 that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Montclair's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Montclair window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Montclair, CA Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a single window can range from $450 to $650. There are a variety of factors that affect how much it costs, such as how energy-efficient the windows are, your property's location, local labor costs, the materials used in designing the windows, the number of windows and styles and sizes of windows.
What kind of window is the best for energy efficiency?
A window's energy efficiency depends on a variety of factors, including 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.
Do you really need to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
How long does it generally take to install windows?
Because a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
