How Installing Energy-Efficient Windows in Herculaneum Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Save on power bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $345 annually on your energy bills in Herculaneum.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Decrease your carbon footprint: In Herculaneum, you can lower your indirect greenhouse gas emissions by about 763 pounds per year after you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in Herculaneum

Let's take a look at the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the national average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. But costs differ remarkably based 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 replacements, which will make your project cost more.

Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $345 a year on your energy bills in Herculaneum.

Requesting free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the whole window, including the trim, frame and sill. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which kind of window installation service you should get, your installer should be able to help you out. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Herculaneum

EcoWatch reviews are different from most reviews since we examine these companies through a sustainability lens. We've evaluated the best window installers in Herculaneum mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Herculaneum, we only included companies that serve the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Herculaneum.

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 rate window installers higher 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 may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, professionalism, cost, warranty, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installers won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide 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 offer 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 been in the industry for a while. Window installers 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.

Herculaneum, MO Window Replacement FAQs

What is the typical cost to install windows?

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

What are the most common types of replacement windows?

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

What do window installers do?

Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.

How often do you need to replace windows?

Windows generally have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.

Should I replace my windows all at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at the same time is the only way to see a noticeable difference. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
