How Installing Energy-Efficient Windows in St. James Saves You Money

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

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In St. James, that's about 307 pounds per year on average.

Estimated Cost of Window Replacement in St. James

Each window replacement company provides various services and has varying price points based on a few factors.

How Much Do New Windows Cost?

According to our research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. But prices vary 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 offer door replacements, which will make your project cost more.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $215 a year on your energy bills in St. James.

We recommend getting free quotes from several window installers to find the one that works best for you.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can recommend the best type for your project. In St. James, the choice will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in St. James

In our search to make your home improvements easier and more eco-friendly in St. James, EcoWatch evaluated dozens of companies before settling on these. We have decided to evaluate the top window installers in St. James mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for St. James, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in St. James.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. Still, 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor 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 years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

St. James, NY Window Replacement FAQs

What is the typical cost to install windows?

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

What kind of window is the most energy-efficient?

A window's energy efficiency is affected by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installers do?

Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.

How do you know it's time to replace your windows?

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

Should I replace all my windows at the same time?

If you're upgrading your windows to get more efficient windows, replacing all your windows at once is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
