How Installing Energy-Efficient Windows in Mehlville Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with 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-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Mehlville, that's about 763 pounds per year on average.
Estimated Cost of Window Replacement in Mehlville
Each window installer provides varying services and has varying price points depending on a few factors.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mehlville homeowners $335+ a year after replacing single-pane windows.
Getting free quotes from multiple providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
When considering window installations, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their advice. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Mehlville
EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Mehlville and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Mehlville area so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand 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
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Mehlville, MO Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to install a window can range between $450 and $650. There are many factors that influence how much it costs, such as your property's location, the number of windows, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and local labor costs.
Which kind of window should I get?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.
How long does it generally take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. 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 isn't necessarily a big factor. Most importantly, the weather should be dry.
