“Just had my house power washed by Kussmaul and it looks like the day that the siding and awnings were installed! Tressin came out before the job was started to greet me personally, and I am glad that he did, he is very personable, knowledgeable and fair. I would definitely have him work on my house again in the future. I did not have pictures to provide because it was raining the day he came out but he still did the work anyway.”

“They did a wonderful job pressure washing my house and cleaning the exterior windows. They are incredibly meticulous and paid such close attention to detail. They even went the extra mile by getting up on the roof to clean my skylights! They left everything perfectly clean afterwards and their pricing is incredibly reasonable for the high quality of work they deliver. Highly, highly recommend! I will be using them again in the future!”

“Kussmaul Co. did a phenomenal job installing our Christmas lights! The house looks beautiful, and they truly went above and beyond — even taking the extra time to clean out our gutters while they were here. I called the last week of November to get our lights scheduled, and they had everything installed in less than a week. Their customer service was amazing, and communication was timely and effortless from start to finish. Highly recommend Kussmaul Co. for anyone looking for reliable, high-quality holiday lighting!”

“PURE CHRISTMAS MAGIC!!! Absolutely incredible service from start to finish. Tressin was professional, quick, and made my house look like it belonged in a Christmas movie. Every light was perfectly placed, and the attention to detail was unreal. My neighbors have stopped to compliment the display. I'd give them more than seven stars if I could! 🎄✨”

“Best power washing service experts on this side of the Rock River!”

“Excellent job by Tressin & team cleaning windows and weeding/mulching my garden. Timely, clean, courteous, efficient and fair price. I'll employ them again.”

“amazing owner and amazing products, end result was beautiful!!”

“Our house looked beautiful during Christmas! Recommend to guests and family we had over”

“Tressin did a phenomenal job pulling weeds, putting down mulch, and cleaning up leftover leaves for us. I reached out asking if he was able to help cleanup the yard and they came two days later and busted it out in one day. Can't recommend their work enough. We also had them do our Christmas lights over the winter and they knocked that out of the park as well. Great people to work with.”

“Cleaned the exterior windows of our house and when they were gone, the large front window somehow looked worse (the rest of the windows looked great from the start). I sent them a pic to inquire, and they immediately came back, redid that window, AND cleaned the inside of that large window (where it turns out a large part of the problem actually was and was just “unmasked” by cleaning the outside). Cleaning the inside was not part of the original job but they really wanted to make sure it looked good and put in the extra work. It looks fantastic now. Service and responsiveness was top notch, and I was incredibly impressed by their professionalism!”

“Permanent lighting looks great whether it's COLORS for any HOLIDAY controlled anywhere by phone or just WARM ACCENT for every night and Security. No more ladders for xmas lights and now can have fun lighting for 4rth of July, Halloween, Thanksgiving, Valentines Day, St Patrick's Day, etc, or not when ever. Pressure washing helped clean up years of grime too. A nice extra touch. Shulda done yrs ago.”

“The friendliest people you’ll ever meet! They don’t just do the job you hired them to do, they clean up and leave your home nicer than they found it. We’ve used a lot of services over the years but the folks at Kussmaul do the best of any company we’ve ever used. We’ve had them wash our windows, clean our gutters, power wash the house, and just purchased LED whole house lighting. We checked out other lighting companies but you need to make sure you ask the right questions. Now our house is the toast of the neighborhood whether lighting our house up for every holiday, Badger or Packer games, or saving me time on hanging Christmas lights; these guys have great products and are true professionals. I’ll be recommending Kussmaul to all my neighbors and everyone I know!”

“Regarding Kussmaul Co. For my permanent lighting system, from concept to completion the entire project was done as smoothly as possible. Tressin and his entire crew were excellent to work with! I would highly recommend Kussmaul Co. for your personal home services.”

“Hi Tressin. I am so pleased with my gleaming windows! I appreciate you accommodating my schedule & helping out on a task I would not attempt . You are fortunate to have Marco on your team! He did such a great job for us and is a nice person to have in our home. Highly recommend your company. Thanks to you all!”

“I had my windows (20+) washed from the outside and more importantly, the front of the house powerwashed to remove an accumulation of spiderwebs and dirt from the two story portico. Everything was cleaned well, this particular worker was careful and did not damage any property or plants. Good work.”
