Denise - Madison, WI
We couldn’t be happier. Had a new patio door installed. Great experience from beginning to end. Prompt quote, continuous schedule updates, installers were amazing. And the work they did is just beautiful. We’ve done four projects with Ganzer and have been happy every time!
New insert windows by Infinity
Jack - Sun Prairie, WI
Jason the salesperson was very professional. He explained my options well. Pricing was competitive. Wasn’t the least expensive or the highest price of our 3 proposals. We choose Ganser Co. because of the history of the company. Work crews were courteous and professional. Ganser Co. has a very good workmanship warranty. And the Infinity windows has an excellent warranty. So if you want a high quality window at a great price, GANSER THATS THE ANSWER!
