How Installing Energy-Efficient Windows in Wauwatosa Saves You Money

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

• 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 497 pounds.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Wauwatosa

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

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, including the location of your home, material, type, size, number of windows and more.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are usually 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 provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a window installation is to clarify whether you want a full-frame or pocket installation.

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. A pocket installation entails replacing a window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation to get, you can talk to your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage present.

We’ve decided to assess the best window replacement companies in Wauwatosa mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Wauwatosa, we only included companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Wauwatosa.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has gotten a lot 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 experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
