How Installing Energy-Efficient Windows in Wentzville Saves You Money

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

• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Save on electricity bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save around $382 annually on your energy bills in Wentzville.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Decrease your carbon footprint: In Wentzville, you can cut your indirect greenhouse gas emissions by about 763 pounds per year when you install energy-efficient windows.

Estimated Cost of Window Replacement in Wentzville

Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you can find from window installers.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200. But prices 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 offer door installations, which will make your project cost more.

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 $382 a year on your energy bills in Wentzville.

Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window installations, there are generally two types that your installer will offer: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

If you’re still debating which kind of installation you need, you can consult with your provider and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage present.

In our hunt to find the most reliable, eco-friendly window installers in Wentzville, the EcoWatch team chose the above companies as the best window installation companies in the city. We have reviewed the best window installers in Wentzville mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your energy 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 cover the city. There are 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 picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand 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

Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other 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 wide range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
