20 Best Window Companies in South Milwaukee, WI (2025 Reviews)

How Installing Energy-Efficient Windows in South Milwaukee Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save $426 a year on your bills.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
• Reduce your carbon footprint: In South Milwaukee, you can cut your indirect greenhouse gas emissions by about 497 pounds per year after you install energy-efficient windows.
• Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in South Milwaukee

When considering window installation, each company provides different services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Even though the typical cost to replace one window is about $600, it can range from $200 to $1,200. These amounts are based on the specifics of your installation, such as size, material, the location of your home, number of windows, type and more.

It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save South Milwaukee homeowners $426+ a year when replacing single-pane windows.

Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window replacements, there are typically two types that your installer will offer: full-frame and pocket installations.

Full-frame installations involve replacing the whole 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 deterioration. Full-frame installations involve more time and labor 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 will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which type of installation you need, you can consult with your provider and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in South Milwaukee

In our search to make your home improvements easier and more eco-friendly in South Milwaukee, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

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

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks 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 nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of South Milwaukee’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of South 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.
