How Installing Energy-Efficient Windows in Wausau Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Save on electricity bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $561 annually on your energy bills in Wausau.
• Protect your valuables: Many energy-efficient 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.
• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Wausau

How Much Do New Windows Cost?

High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation involves installing a new window within the old frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you choose what’s best for your needs. In Wausau, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Wausau

EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. We have decided to assess the best window installation companies in Wausau mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Wausau, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Wausau.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. 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

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window 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 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 be certain 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 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.
