Columbus, OH
Cole learned home projects the way most people do — by doing a few of them wrong the first time. He writes the practical math side of DIY: how much paint you actually need, whether a flooring quote is fair, what a project really costs before you start. He's a hands-on hobbyist, not a licensed contractor, so he sticks to the planning and the numbers and leaves the code-and-permit calls to the pros.
