How Installing Energy-Efficient Windows in Koshkonong Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

  • Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In Koshkonong, you can cut your indirect greenhouse gas emissions by about 715 pounds per year after you upgrade to energy-efficient windows.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Koshkonong

Let's go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Even though the average of installing a single window is about $600, it can range anywhere from $200 to $1,200. These estimates vary depending on the specifics of your installation, like the location of your home, size, material, type, number of windows and more.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Koshkonong 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. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window replacements, there are typically two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're still debating which kind of installation you should get, you can talk to your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Koshkonong

In our hunt to find the most reliable, eco-friendly window installers in Koshkonong, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Koshkonong and assigned rankings using the following methodology:

Service Area

Because this is a guide for Koshkonong, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Koshkonong.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies 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 wide range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you 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 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.

Koshkonong, WI Window Replacement FAQs

How much should window installation cost?

The typical cost of replacing one window can range from $450 to $650. There are a variety of factors that affect how much it costs, such as your property's location, the materials used in designing the windows, styles and sizes of windows, the number of windows, how energy-efficient the windows are and local labor costs.

Which type 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 the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Can you install your 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 know-how, we recommend getting a professional to do it for you.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.

Should I replace all my windows at once?

If you're upgrading your windows to save on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
