How Installing Energy-Efficient Windows in Hazelwood Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:

  • Protect your investment: If you have a relatively old home, 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 property if you decide to sell.
  • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient windows can help lower that amount, which helps you save more on your bills.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Hazelwood, that’s about 763 pounds per year on average.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Hazelwood

Each window installer offers varying services and has varying costs depending on several factors.

How Much Do New Windows Cost?

According to our research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, like material, the location of your home, type, number of windows, size and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which window installation service you should get, your installer can advise you. 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 Hazelwood

In our hunt to make your home improvements easier and more eco-friendly in Hazelwood, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have decided to evaluate the best window replacement companies in Hazelwood mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut 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 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

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

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of 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 most other categories, including quality of installation, warranty, quality of parts, cost, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious 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

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Hazelwood, MO Window Replacement FAQs

How much should a window install cost?

The typical cost to replace a single window can range from $450 to $650. There are a variety of factors that influence how much it costs, including the materials used in designing the windows, your property’s location, the number of windows, styles and sizes of windows, how energy-efficient the windows are and local labor costs.

Which kind of window is the best?

A window’s energy efficiency depends on several 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 since they are certified by the U.S. Department of Energy.

Can I install my own windows?

If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or experience, we don’t recommend doing it on your own.

What time of year is a good time to replace my windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure 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.

How long does window installation take?

Because the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
