How Installing Energy-Efficient Windows in Milwaukee Saves You Money

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

• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Milwaukee

Windows come in different shapes, styles and purposes, so costs and services will vary greatly based on your project. Below, we detail the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Although the national average cost of replacing one window is around $600, it can range from $200 to $1,200. But costs will differ considerably depending on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Milwaukee homeowners $466+ a year when replacing single-pane windows.

How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, although 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 types of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

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

How We Choose the Best Window Installers in Milwaukee

EcoWatch reviews are different from other reviews since we’re examining these companies through a sustainability lens. We’ve decided to evaluate the top window replacement companies in Milwaukee primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. 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 Milwaukee, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Milwaukee.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as 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. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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