How Installing Energy-Efficient Windows in Potsdam Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to think about making the switch:

  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.

Estimated Cost of Window Replacement in Potsdam

When looking into window installation, each company offers varying services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our market research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. These numbers vary depending on specific characteristics of your installation, like number of windows, type, size, material, the location of your home and more.

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

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve 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. These installations are more involved and will raise the total cost. A pocket installation entails replacing a window within the old frame. So, instead of tearing out the whole unit and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Potsdam

In our search to find the most reliable, eco-friendly window installers in Potsdam, the EcoWatch team landed on the above companies as the best window installation companies in the city. We’ve reviewed the best window installers in Potsdam mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Potsdam, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Potsdam.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you get. 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

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the most 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

Protecting your investment in new windows is important. For that reason, window installation companies that provide 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 proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Potsdam, NY Window Replacement FAQs

How much does a window install cost?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

The most common types of windows for homes are double-hung and single-hung windows, awning windows, transom windows, slider windows, picture windows, bay windows and casement windows.

Can I replace my own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.

When is it time to replace your windows?

Windows usually have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.
