How Installing Energy-Efficient Windows in Wentzville Saves You Money

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

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Save money on energy bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $382 annually on your energy bills in Wentzville.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Wentzville, that’s about 763 pounds per year on average.

Estimated Cost of Window Replacement in Wentzville

Let’s take a look at the cost of replacing your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Generally, Wentzville homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But prices vary 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 installations, which carry a higher price tag.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Wentzville homeowners $382+ per year after replacing single-pane windows.

We advise requesting free quotes from several window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company can recommend the best type for your project. In Wentzville, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Wentzville

EcoWatch is different from other reviewers since we evaluate these companies through a sustainability lens. We have decided to evaluate the top window installers in Wentzville mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower power 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 only included companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Wentzville.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Wentzville, MO Window Replacement FAQs

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

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

What are the most common kinds of replacement windows?

There are several different kinds of windows you can get for your house, such as double-hung and single-hung windows, picture windows, slider windows, bay windows, awning windows, casement windows and transom windows.

Can you install your own windows?

If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or know-how, we recommend hiring a professional.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.

How long does it typically take to install windows?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
