20 Best Window Companies in West Allis, WI (2025 Reviews)

How Installing Energy-Efficient Windows in West Allis Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to make the switch:

• 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 due to their ability to filter out damaging UV rays.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.
• Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 497 pounds.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in West Allis

Windows come in different purposes, shapes and styles, so costs and services will differ tremendously based on your project. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

On average, homeowners in West Allis can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will add extra costs to your project.

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

Something else that influences the total cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your installers will replace the whole window, including the frame, trim and sill. 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 slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In West Allis, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in West Allis

In our hunt to find the most reliable, eco-friendly window installers in West Allis, the EcoWatch team examined dozens of companies before settling on these. We have decided to review the best window replacement companies in West Allis mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a sizable 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

Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
