How Installing Energy-Efficient Windows in Des Peres Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, such as:

  • Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Des Peres

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

How Much Do New Windows Cost?

Though the national average of installing one window is around $600, it can range from $200 to $1,200. This is because of the fact that the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Des Peres homeowners $328+ each year after replacing single-pane windows.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, 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 kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to recommend the best type for your project. In Des Peres, the choice will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Des Peres

In our hunt to make your home improvements easier and more eco-friendly in Des Peres, the EcoWatch team assessed many companies before landing on these. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

Since this is a guide for Des Peres, we paid more attention to companies that serve 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 Des Peres.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
