WASCO Windows opened in Milwaukee in 1957 as Wisconsin Aluminum Supply Company, and was purchased by Dave Paulus in 1983. At that time, the company manufactured aluminum storm windows, siding and awnings. Under Paulus’ direction WASCO became the first company in this area to manufacture then-new vinyl replacement windows. Since 1983 the Paulus family has transformed WASCO into a company that leads the industry in manufacturing and installing highly energy efficient window products, engineered for Wisconsin’s unique climate.

Abrahamson Services provides a wide range of services to the 4 county Milwaukee area. Anything from windows, doors, roofs, gutters/toppers/cleaning, to roof raking, ice removal and interior work

"Ken was fantastic from start to finish. I hired him to remove an old basketball hoop, pour new cement, and install a new one. The job turned out to be much tougher than expected—the old cement was nearly impossible to break up and the clay ground was hard to dig deeper for the required dept —but Ken handled it like a pro, using a jackhammer and digging through hard clay soil without complaint. Despite the extra work and materials needed, he stuck to his original price even when I asked to pay him more, which speaks volumes about his integrity. He returned a few days later to assemble the hoop, and the final result was perfect—every measurement was spot-on. Ken went above and beyond, and I wouldn’t hesitate to hire him again. Highly recommended!"

Windows questions, answered by experts

Avoid any abrasive tools, like rough cloths or steel wool, which can permanently scratch and damage your windows. Hard water can leave spots or streaks, so distilled or filtered water is usually preferred. Finally, check if your windows have any special features, like tinting, as this may impact what type of cleaning solution to use.

Smart windows can last anywhere from 10 to 50 years. It depends on the type and brand of smart window you choose and how much usage your windows get.

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

There are more than five window types, but five of the most popular types include casement windows, sliding windows, double-hung windows, picture windows, and awning windows. Each style offers something different. Some are great for ventilation, others for letting in light, and some can do a bit of both. For kitchens, specifically, it helps to think about how often you’ll open the window, how easy it is to clean, and whether it fits well in the space you have.

High winds can be harmful to casement windows and all types of windows. Because casement windows can swing outward, high winds could slam the window against the side of the house, bend the hinges, or even rip the window off of the hinges. If you hear some strong gusts outside, it’s best to pull the casement windows shut until it all blows over.
