How Installing Energy-Efficient Windows in Fort Atkinson Saves You Money

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

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Fort Atkinson, that’s about 715 pounds per year on average.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.

Estimated Cost of Window Replacement in Fort Atkinson

Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you’ll find from window installers.

How Much Do New Windows Cost?

Though the national average cost of installing one window is around $600, it can range from $200 to $1,200. This is because of the fact that the cost of window installations are based on several 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.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $494 a year on your energy bills in Fort Atkinson.

Asking for free quotes from several companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable damage or rot. Because these installations are more involved, they will raise the total cost. Pocket installations are simpler and won’t cost as much, as they involve simply 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 still debating which type of installation you need, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Fort Atkinson

In our search to find the most reliable, eco-friendly window installers in Fort Atkinson, the EcoWatch Reviews team assessed many companies before deciding on these. We’ve decided to assess the top window replacement companies in Fort Atkinson mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower 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 the Fort Atkinson area so you can find the right window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have positive things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. 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.

Fort Atkinson, WI Window Replacement FAQs

How much does window installation cost?

The typical cost to install one window can range between $450 and $650. There are several factors that affect how much it costs, including how energy-efficient the windows are, the number of windows, styles and sizes of windows, local labor costs, the materials used in designing the windows and your property’s location.

Which type of window should I get?

A window’s energy efficiency is affected by a variety 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.

Can you replace your own windows?

While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

When is it time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
