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!"

Why replace the whole window when you can replace Just the Glass! Signs of a seal failure can be seen as "foggy" glass or a purple hue on the outside. A closer look can reveal mold spots or "dirty" glass that is on the inside of the thermopane. In most cases, just the glass can be replaced for a fraction of the cost of new windows. We provide free estimates and our lead time is short. We aim to have your project complete in 2-3 weeks from approval. Our glass is custom ordered locally right here in Wisconsin. Need a storm door installed or replaced? We can help with that too. We are a locally owned and operated company that values honesty and integrity, and treats your home as if it were our own. We specialize in glass installation and repair. Our services are customized to the individual project, paying close attention to the details of each project that we're involved with. We look forward to building long-term relationships with our clients and guarantee your satisfaction!

FAQs for window service projects in Sullivan, WI
If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift.
Replace multiple windows at once to bundle your purchase
Inquire about discounts, coupons, or special offers
Consider window repair as soon as you see damage to help prevent the need for replacement
Maintain your windows often by inspecting your windows for drafts, leaks, and cracks
There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
