How Installing Energy-Efficient Windows in Fond du Lac Saves You Money

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

• 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.
• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty.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.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 715 pounds.
• Save on electricity bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.

Estimated Cost of Window Replacement in Fond du Lac

Let’s go over the cost of replacing your windows and the types of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. These amounts vary depending on the specifics of your installation, such as size, number of windows, type, material, the location of your home and more.

Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Asking for free quotes from multiple companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the full window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot or deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation means replacing a window without removing the complete frame, which is generally less expensive than a full-frame installation.

If you’re not sure which type of window installation service you need, your installer can advise you. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Fond du Lac

In our hunt to make your home improvements easier and more eco-friendly in Fond du Lac, the EcoWatch Reviews team assessed many companies before settling on these. We have assessed the best window installation companies in Fond du Lac mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window 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 super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain company, it won’t be 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, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. 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.
