How Installing Energy-Efficient Windows in Andover Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, such as:

• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
• Save money on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $434 annually on your energy bills in Andover.

Estimated Cost of Window Replacement in Andover

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

Although the typical cost to install a single window is about $600, it can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will make your project cost more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Asking for free quotes from several companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the whole window, including the frame, sill and trim. A pocket installation involves installing a new window without replacing the frame. This means instead of removing the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

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 Andover, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Andover

EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer 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 Andover area so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks 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 most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of installation, professionalism, quality of parts, warranty and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to make sure 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

Because of Andover’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Andover window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
