How Installing Energy-Efficient Windows in Fondulac Saves You Money

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

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Decrease your carbon footprint: In Fondulac, you can reduce your indirect greenhouse gas emissions by about 642 pounds per year after you upgrade to energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $318 a year on your bills.

Estimated Cost of Window Replacement in Fondulac

When considering window installation, each company provides different services and costs. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Generally, Fondulac homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost varies depending on several factors, such as number of windows, type, the location of your home, size, material and more.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Fondulac homeowners $318+ per year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Fondulac

EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Fondulac area so you can find the best window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have nice things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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