How Installing Energy-Efficient Windows in Ellisville Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Ellisville

When researching window installation, each company offers different services and costs. Let's look at some average costs and services.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, such as number of windows, type, size, material, the location of your home and more.

It's also worth noting that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Ellisville home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window within the old frame. This means instead of taking out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Ellisville

In our search to make your home improvements easier and more eco-friendly in Ellisville, the EcoWatch Reviews team examined many companies before landing on these. We have reviewed the best window replacement companies in Ellisville mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Ellisville so you can find a quality window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most 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 cost, quality of installation, professionalism, quality of parts, warranty 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 offer a range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

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

Ellisville, MO Window Replacement FAQs

How much does a window install cost?

The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on several factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the types of windows?

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

Do you really have to use a window installation company?

Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but warmer weather is typically better. 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 your house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
