How Installing Energy-Efficient Windows in Mehlville Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
Estimated Cost of Window Replacement in Mehlville
Let's go over the cost of window installation and the kinds of services offered by installers.
How Much Do New Windows Cost?
Typically, Mehlville homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at about $600. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.
It's also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Mehlville home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from multiple providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has noticeable rot. Full-frame installations are more involved and will raise the total cost. Pocket installations are simpler and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Mehlville, the decision will mostly depend on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Mehlville
EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. We have decided to evaluate the best window installation companies in Mehlville primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities 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 company on this list to ensure its contractors are well-qualified and that the company has received a lot 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 consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, professionalism, cost, quality of installation, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most 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. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Mehlville's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Mehlville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mehlville, MO Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of installing one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, remember 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 affected 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 usually the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installers cover the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. 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 your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
