How Installing Energy-Efficient Windows in Randolph Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Randolph, that’s about 206 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Randolph
Each window replacement company provides varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
Generally, Randolph homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These figures vary depending on the specifics of your installation, such as the location of your home, type, number of windows, size, material and more.
It’s also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Randolph home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per 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 you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re still debating which kind of installation to get, you can consult with your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Randolph
EcoWatch is different from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Randolph and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Randolph area so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has gotten lots 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 consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure 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 significant investment, so you’ll want to be certain that investment is protected. Window installation companies that offer 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 proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Randolph, NJ Window Replacement FAQs
How much should a window install cost?
The typical cost to install a window can range from $450 to $650. There are many factors that affect the price, including your property’s location, the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are and the number of windows.
What type of window is the best for energy efficiency?
A window’s energy efficiency depends on a number of factors, including 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.
When should I use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it’s best left to the professionals.
What time of year should I replace my 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 ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to see a noticeable difference. However, if you have only a few windows that are broken or leaky, you can replace just those.
