How Installing Energy-Efficient Windows in St Charles Saves You Money

When you switch to energy-efficient windows, you may see several benefits, including:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $308 annually on your energy bills in St Charles.

Estimated Cost of Window Replacement in St Charles

Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you'll find from the average window installation company.

How Much Do New Windows Cost?

Generally, St Charles homeowners can expect their window installations to range from $250 to $1,200. The average cost is at approximately $600. This is because window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save St Charles homeowners $308+ per year after replacing single-pane windows.

Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still debating which type of installation to get, you can talk to your provider and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in St Charles

In our search to find the most reliable, eco-friendly window installers in St Charles, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We've evaluated the best window installers in St Charles primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for St Charles, we only included companies that serve the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in St Charles.

Work Quality

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

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, professionalism, cost, warranty and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

St Charles, MO Window Replacement FAQs

What is the average cost to replace windows in a home?

The national average cost to install one window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't 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 — they're certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies provide?

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

How long does window installation take?

Since the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.

Should I replace all my windows at once?

If you're upgrading your windows because of energy-efficiency, replacing all your windows together is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
