How Installing Energy-Efficient Windows in Mehlville Saves You Money

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

  • Save on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your house.
  • Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Mehlville

When researching window installation, each company provides different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

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

It’s also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Mehlville home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Getting free quotes from multiple providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step of a window replacement is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Mehlville

In our hunt to make your home improvements easier and more eco-friendly in Mehlville, the EcoWatch team assessed dozens of companies before settling on these. We’ve assessed the top window installation companies in Mehlville mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your energy 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 Mehlville, we only included companies that provide services to 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 Mehlville.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, warranty, quality of parts, professionalism, quality of installation and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Mehlville’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Mehlville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Mehlville, MO Window Replacement FAQs

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

The national average cost to replace a window is about $600 but can range from $200 to $1,200, based on several factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

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

What do window installation companies do?

Window installation professionals cover the entire process — from replacing your old windows with brand-new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.

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 make sure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
