Depends. My wife does almost all of the cooking, a lot of the routine cleaning, and laundry.
I do almost all of the renovations, all of the car maintenance, and a good portion of the yard work. I would say that if you broke it down and charted hours over time, she clearly does more consistent work, but when I'm on a project, it could be dozens of hours. When I was doing our floors (800is sq ft of hardware and subfloor, plus removal of carpeting and laminate through about 3000 sq ft of our house) it was several weeks where I'd work my day job, and come home around 5:30 and work till 11 pm on the house.
A casual observer would just see that I come home most days, work out, and then put my feet up.
