Wasco The WASCO Difference is taking the time to carefully craft every window individually with the attention to detail that you and your home deserve. Take a look and we're confident you'll like what you see.
Services
Commonly called "Tilt & Turn windows, " our European windows are made from the best components from Germany, the United States and Canada. They are available as a single Tilt & Turn Window, a true mullionless French Window (which allows both panes to be opened or a single pane to be tilted) or in a variety of multi-pane designs.
How your windows look is as important as how they perform. WASCO offers a number of exterior and interior color combinations, clear or frosted glass, multiple grid options and the choice of full or half screens to help customize your windows to your home. WASCO Premium Windows are available in white or almond REHAU RAU-PVC with three optional woodgrain interiors.
From door replacements and conventional new construction to high energy performance homes, WASCO can fit you with the right door, ensuring maximum security, energy efficiency and beauty for your home. The GENEO series, made from high tech, six-chamber REHAU RAU-FIPRO profiles, is the right choice for passive or high energy performance homes.
A product of WASCO's Milwaukee Fensterwerk, Balcony and Terrace Doors offer better thermal performance and far higher security than leaky sliding doors. Balcony doors are ideal where it is not necessary to lock or unlock the door from outside, such as for patio, balcony and deck applications. Terrace doors retain the tilt-in feature but add an exterior lock and handle.

WASCO was timely in their replacement of all windows. The weather was not in their favor so they had to come back and replace the rest on the third day. I liked the way they prepared themselves for work inside the house to keep it free from dust. I'd say my only suggestion is to watch for nails and screws more closely before leaving after the job is complete. We requested new trim around bigger windows and we are to stain them.

We replaced all of the windows in our 1923 Cape Cod with Wasco Tilt-and Turn windows a few years ago. My wife is German and I've spend enough time abroad to admit that it's just a superior window design. We can tilt them in the rain or when we're not home. We can throw them wide open on nice days and get that fresh breeze. Better view, easier to clean than even the best double-hung.

When we first contacted them they up a meeting to see the product in action with people who actually had them in their house. (You're welcome to see mine.) They sent someone out to measure each window individually and determine which direction they wanted to swing open. *Every single window* We have tiny casement window on our stairs, and it was noted that would need to be tempered glass.

Attention to detail and communication was awesome. We had contacted a half dozen other companies for quotes, and were really clenching our teeth waiting to hear what triple pane, custom produced, niche market windows would cost. It was more than the cheapest vinyl offer by maybe 30%. But it was also half what "premium" double pane wood would have been.

We met with several window companies and WASCO not only had the best quality but they also had the best price. The warranty is exceptional. Our salesman, Jeremiah, wasn't pushy and was very knowledgeable. Service: Window installation

I had Wasco Windows replace all 11 windows in my home a few years ago. Took a tour of their facility and watched how the windows were constructed. The installers came on time and did an excellent job. They even calked some areas that weren't part of the windows install process, i would highly recommend them. I noticed an immediate drop in my heating bill the following winter.

Over a period of some 20 years, we have had about 20 Wasco vinyl windows installed. Most of them are casement windows because we like the idea that the harder the wind blows the tighter the seal. Our last window was installed in 2014. Wasco has kept their end of the contract by servicing the windows in disrepair but rarely has there been a problem with their windows.

Even the earliest models were well made and the newer models have a better designed latching system. The aluminum screens have always been substantial. Before we had our windows installed, the winter wind howled through the joints of our old, so difficult to clean, double hung windows. Not so now. Moreover, the new windows are a pleasure to clean affording an almost instant clear view of our lovely street.

My husband and I purchased nine windows from WASCO over twenty years ago are are still very pleased with them. We only had one issue many years after purchasing them and the company came immediately and put in a new window with no questions asked. The company is an honest and fair business and all the employees are polite and professional. I have recommended them for several years to all my friends and family. I wish there were more companies that you could trust to do excellent work at a fair price.

WASCO provides detailed information on services, how windows are constructed, being WI based, and available for any questions. We had our home done in two schedules a year apart. We had a request of keeping some of our old windows, because of the style, that we used for decoration. The work crew ensured we received them after removal. Both installers were professional, friendly, on time, and open to questions. I would recommend this company for the professionalism and warranty.

We had new windows installed in our house this past June. The whole process was fantastic! From the start of visiting the showroom, to the installation. John was a great salesman, wasn't push, and wanted us to be sure we were making the right decision. Installation was delayed a little bit, but that was because of the pandemic. We weren't in a hurry, so it didn't affect us as to when they were installed.

We absolutely love our windows, and would use WASCO again! We were recommended to WASCO by 3 different friends who have used them. I would highly recommend you to friends and family.

August, 2021 WASCO replaced 14 windows in our home. We are very happy with the windows and in the past 2 months have had no problems with them. My husband, who works in the Mechanical contracting industry, did a lot of research on windows and felt these were a good choice. He spent hours asking questions and getting answers. We appreciated that. The crew consisted of Dave and Nick. They are seasoned window installers and did a wonderful job.

It's been about 10 years and LOVE my windows. I needed some little catches yesterday (a little safety device to restrict how high they can open) and Steve just gave them to me. I so recommend them, And they are stylish too. My energy bills have gone down and stay down. Ted Tuescher was my installer and you couldn't have had a nicer guy. Service: Window installation

We LOVE our WASCO Windows. We only replaced our main living room and garage windows, but definitely plan on going with WASCO in the future when we get around to the other windows in the house. The salesperson wasn't pushy, the installers were nice and picked up after themselves afterwards. After a year I still believe the quality of windows are great.

We had 5 new WASCO windows installed in 2020 to update our kitchen and garage windows. The windows are extremely high quality, also the customer service and the installation service was great! We are extremely happy with our decision to go with WASCO to update our pre-existing windows. Also, we used the WASCO window lifetime warranty to replace some of our existing WASCO windows (installed over 20 years ago) that had some small imperfections - the warranty service was amazing!

We had All our old windows replaced (15) and our other leaded glass windows wrapped with vinyl. Was on was outstanding and amazing to work with. The installers were great, fast and efficient. The sales people that we worked with were very good and gave us great options to choose from and were not pushy. The scheduler was timely and kept us informed. This is the second home that we have had Wasco replace our windows. I always recommend them to anyone looking for window replacements. LOVE THEM!

Wasco replaced all my windows and my patio door in 2017. The installation was a bit slow as it took my entire vacation (5 days) to complete. The products though have been great. A few minor issues cropped up but all were taken care of in a timely manner. Happy with my windows and patio door.

We met with many window companies here in the Milwaukee area but decided on WASCO because of the knowledge and comfort that our salesman (John Hanus) provided to us about the product, service and warranty that WASCO provides. We spent $17,692.00 on WASCO windows over 10 years ago and are still 100% satisfied with our windows and would not hesitate to make the same decision all over again.

There are parts of my Wasco Windows that I love. Wisconsin made, triple pane, tilt n turn, heavy duty mechanics solidly built. Spent a lot of money on replacing every window in the house and love to show everyone who comes over how many lock points are activated when closing. Two things went very wrong. Each of my right side handles is lower than the left one.

On EVERY window. After three years and three attempts I still do not have screens for the four windows in my living room. How can a company not get the right size screens for windows they made? The last time they made me measure it and I had only measured the opening, not knowing that when they give measurements they add something (1/2inch?) to include extra for a surrounding flange.

The end result was the screens fit completely within the opening. I should not be responsible for measuring. Frankly, the screens I do have installed on the other windows are the worst functioning screens ever. They do not lie flush against the window frame (arrived bowed and the builder did his best to bend them the other way) some of the pins had to be forced at awkward angles to meet the corresponding holes, and the house ends up filled with bugs if I dare open any windows at night.

I do not like A/C, so this is a major pain point for me. Every summer I curse my Wasco windows. I just built another building and went with Anderson 100 inexpensive windows. The windows are not as efficient or cool, but the screens are GREAT.

Wasco makes a beautiful American made product with professionalism at a great cost. They replaced 4 old pully-type windows with a gorgeous bay window. I highly recommend this small business vs the over priced giants of the industry.
