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.
