Jason had great ideas!
Diana - Wisconsin Dells, WI
We told Jason what we thought we wanted and he made it happen and more. We look forward to working with him next year on another window project! We haven’t had the windows installed yet.
Anne - Madison, WI
Wow, our house has been transformed by Ganser Company from top to bottom (literally)! They provided us with a new roof, gutters, downspouts, siding, windows, and sliding glass door. Plus added additional insulation in the attic to increase the R value. Our 1983 house has been updated for the 21st century and looks brand new! Our neighbors all love how it looks as much as we do. We are so proud every time we pull into our driveway.
Entire Bathroom Remodel
Chris - Fitchburg, WI
This project was the complete remodeling of a bathroom-from-hell.I was very satisfied with the quality of the work and the punctuality, work ethic, friendliness, and respectfulness of Mark, David and David. Work included tearing down walls and remodeling of a tiny, poorly laid out bathroom, including re-piping, new electrical outlets, shower drain relocation in foundation, installation of lovely shower unit, toilet, and vanity, drywalling and priming. Result was a much expanded and spacious, bright, and modern bathroom. We are very pleased.
Kristin - Madison, WI
They were super professional, quick, and the bathroom install was well executed!
Great product, work and service!
Gregg - Belleville, WI
In the past 15 months we have used Ganser for three major home improvement projects; attic insulation, new roof, and new siding. We are very pleased and satisfied with their work. All the people have been very professional, hardworking, and respectful. Also we have been very impressed with their attention to customer service. We felt like they took the worry out of the projects. In addition, we really like their warranties. In summary, we are very happy with their work on all the projects.
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!
Glenn - Jefferson, WI
We do think Marc did a great inspection of our roof concerns and construction of our home. See you again THANKS Glenn and Shirley
