How Installing Energy-Efficient Windows in Millbury Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:

• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Millbury, that’s about 139 pounds per year on average.
• 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.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Installing energy-efficient windows can help reduce that amount, which helps you save $482 a year on your bills.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Millbury

When considering window installation, each company offers varying services and costs. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

Though the national average cost to replace a single window is around $600, it can range anywhere from $200 to $1,200. Costs will vary significantly depending on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Millbury home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable deterioration. Because these installations are more involved, they will increase overall costs. A pocket installation involves replacing a window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which type of window installation service you need, your installer can help you out. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Millbury

EcoWatch differs from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Millbury and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Millbury, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Millbury.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well 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 installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
