This logotype is very unique. Even though the word is "one" a line slashing thorough is appealing to the eye. It shows two words saying "one" the darker bold font, and the light font. It shows good use of alignment and contrast.
I like the left logo idea on the left, under "Logo Variations". Again, would have "WoH" with letters (that perhaps would also look like a cleaning/wizard-related drawing at first glance) and under a simple "Wizard of Homes"
