How Installing Energy-Efficient Windows in Mahopac Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Better temperature control in your home: When you live in a city like Mahopac where the winters can be very cold, you usually need to depend on your heater to keep your home warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.
  • Better temperature control in your home: Energy-efficient windows can decrease the amount of cool air lost through your windows when cooling your home.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Mahopac, that's about 65 pounds per year on average.

Estimated Cost of Window Replacement in Mahopac

Windows come in different styles, shapes and purposes, so costs and services will differ greatly depending on several factors. Below, we go over the average cost and services that you'll find from window installers.

How Much Do New Windows Cost?

Generally, homeowners in Mahopac can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mahopac homeowners $332+ each year after replacing single-pane windows.

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

What Services do Window Installers Offer?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage. Because full-frame installations are more involved, they will increase overall costs. A pocket installation involves installing a new window within the old frame. This means instead of taking out the whole window and rebuilding 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 understand what's best for your needs. In Mahopac, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Mahopac

The EcoWatch Reviews team differs from most reviewers since we're examining these companies through a sustainability lens. We have assessed the best window replacement companies in Mahopac primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Mahopac so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window 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

Customer feedback is another super important review factor. If most customers don't have nice feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Mahopac, NY Window Replacement FAQs

What is the typical cost to install windows?

The typical cost of replacing one window ranges between $450 and $650. There are several factors that influence how much it costs, including the number of windows, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows, your property's location and local labor costs.

What type of window is the most energy-efficient?

A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can you install your own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.

How long does it typically take to install windows?

Since a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
