How Installing Energy-Efficient Windows in Oconomowoc Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• Decrease your carbon footprint: In Oconomowoc, you can cut your indirect greenhouse gas emissions by about 497 pounds per year after you upgrade to energy-efficient windows.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
• Save money on electricity bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $483 annually on your energy bills in Oconomowoc.

Estimated Cost of Window Replacement in Oconomowoc

Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you’ll find from window installers.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oconomowoc homeowners $483+ per year after replacing single-pane windows.

We advise requesting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Oconomowoc, the choice will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Oconomowoc

The EcoWatch Reviews team is different from other reviewers since we look at these companies through a sustainability lens. We’ve evaluated the top window installers in Oconomowoc mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, professionalism, quality of installation, cost, quality of parts and more.

Cost

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

Warranty

As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies with 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.
