How Installing Energy-Efficient Windows in Lemay Saves You Money

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

  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 763 pounds per year on average.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Lemay

Each window installation company offers varying services and has varying price points depending on several factors.

How Much Do New Windows Cost?

Even though the national average cost to install one window is about $600, it can range from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Lemay home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from multiple window companies to find the one that works best for you.

What Services do Window Installers Offer?

There are typically two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re unsure which window installation service you need, your installer can help you out. Generally, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lemay

EcoWatch reviews are different from most reviews since we’re examining these companies through a sustainability lens. We’ve decided to review the top window installers in Lemay primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. 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

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Lemay so you can find the best 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 company featured on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest 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 previously, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide 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 installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Lemay, MO Window Replacement FAQs

How much should window installation cost?

The national average cost of installing one window is around $600 but can range from $200 to $1,200, depending on a few different 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, 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 kind of window is the most energy-efficient?

A window’s energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installation professionals go to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
