At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

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!

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.

"Needed warranty repair on 11 windows. The Appleton service manager drove up to me, did all the work onsite. quick and efficient. Windows are like new again."

Windows questions, answered by experts

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

Because bay windows are a combination of three windows, there are many options for how wide or tall they can be. That said, individual windows come in standard sizes, and you can use those as a guide for the width and height of your bay window.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

Replacing basement windows can be worth the cost if replacement is necessary. If your windows are leaking and leading to water damage in your basement, it’s absolutely worth replacing them. Similarly, if your basement windows are no longer insulating your basement or pose a security risk, you need to replace them.

In some cases, you may be able to save money by repairing a window instead of replacing it. A contractor can help you decide the right course of action.
