How Installing Energy-Efficient Windows in Wentzville Saves You Money

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

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save money on electricity bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $382 annually on your energy bills in Wentzville.

Estimated Cost of Window Replacement in Wentzville

Windows come in various shapes, styles and purposes, so costs and services will differ remarkably depending on several factors. Below, we detail the average cost and services that you'll find from window installers.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But costs will vary significantly depending on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

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

Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation entails installing a new window within the existing frame. So, instead of tearing out the whole window and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're not sure which window installation service you need, your installer should be able to help you out. Generally, the choice depends 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 Wentzville

The EcoWatch Reviews team differs from most reviewers because we evaluate these companies through a sustainability lens. We have reviewed the top window installation companies in Wentzville mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your 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 Wentzville, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Wentzville.

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 type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don't have nice feedback about their service from a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like 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. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Wentzville's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Wentzville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Wentzville, MO Window Replacement FAQs

How much should window installation cost?

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

Which type 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 get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or know-how, we recommend hiring a professional.

What time of year is a good time to replace my windows?

While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation more difficult.

How often should you 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 time to have them looked at by an expert to determine if they are in need of a repair or replacement.
