How Installing Energy-Efficient Windows in Jennings Saves You Money

When you switch to energy-efficient windows, you may see some perks, such as:

  • Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Decrease your carbon footprint: In Jennings, you can lower your indirect greenhouse gas emissions by about 763 pounds per year after you switch to energy-efficient windows.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Jennings

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the typical cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. This is because window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

It’s also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Jennings home translates to 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 upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide 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 are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has noticeable deterioration. These installations are more involved and will raise overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Jennings, the choice will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Jennings

In our search to find the most reliable, eco-friendly window installers in Jennings, EcoWatch chose the above companies as the top window installation companies in the city. We’ve reviewed the top window installers in Jennings primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce 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 the Jennings area so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, quality of installation, cost, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to make sure 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 sizable 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

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

Jennings, MO Window Replacement FAQs

What is the typical cost to install windows in a home?

The national average cost of replacing one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

When should I use a window installation company?

Unless you have home repair skills and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated 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.

What time of year is the best time to replace my windows?

Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.

How do you know it’s time to replace your windows?

Windows usually have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have an expert take a look at them to determine if they need any repairs or replacements.
