How Installing Energy-Efficient Windows in Webster Groves Saves You Money

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

  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Webster Groves

Each window installer offers various services and has varying price points depending on a few factors.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200. But costs will vary significantly depending on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $376 a year on your energy bills in Webster Groves.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In Webster Groves, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Webster Groves

In our search to make your home improvements easier and more eco-friendly in Webster Groves, the EcoWatch Reviews team assessed dozens of companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Webster Groves so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, cost, professionalism, warranty, quality of parts and more.

Cost

This one is a give-and-take: as with other services, cheap window installers won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Webster Groves’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Webster Groves window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Webster Groves, MO Window Replacement FAQs

What is the average cost to install windows?

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

What are the most common types of replacement windows?

The most common types of windows for homes include: transom windows, picture windows, awning windows, slider windows, double-hung and single-hung windows, casement windows and bay windows.

What services do window installation companies offer?

Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
