How Installing Energy-Efficient Windows in Sappington Saves You Money

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

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Sappington

Each window installer provides varying services and has varying costs depending on several factors.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. This is because of the fact that the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $327 a year on your energy bills in Sappington.

Getting free quotes from multiple providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the total window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Sappington, the decision will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Sappington

In our hunt to find the most reliable, eco-friendly window installers in Sappington, EcoWatch landed on the above companies as the top window installation companies in the city. 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 installers that serve Sappington so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installers won't always 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

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

Sappington, MO Window Replacement FAQs

What is the typical cost to install new windows in a home?

The average cost to replace a window can range from $450 to $650. There are a variety of factors that influence the price, such as styles and sizes of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are, the number of windows and your property's location.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies offer?

Window installers go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How often do you need to replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
