The windows look wonderful and were exactly what we wanted. The service and installation were very professional and high quality.
Good service, at a respectable price
Pat - Madison, WI
Had a deck door and updated gutters put in by Ganser. Process went really smoothly, they kept in constant contact in the time leading up to the install for any status updates, and the price was fair. I'd go back to them again.
Jon - Oregon, WI
Jason was honest and fun to work with. He did a great job with planning our project. The installers were awesome. The work was done quick and perfect. The new windows look great and the woodwork looks better than the original. Our repainted front door is just what we wanted.

The lead person on the 2 man crew was careful, very efficient, clean, polite, good to his subordinates and knew the job! He worked as hard as 2 people to get our remodel done and in perfect shape! We are very pleased with end result.

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.
