The second approach
What happens when one person runs the whole business?
I was that person.
In 2000 Lorrie and I decided to start our own company and had no money to do it with. My younger brother, maybe a year out of college, called and offered to loan us $2,500. That paid for the technical trade exam and the business management exam Arizona requires to become a licensed contractor, and there was enough left over to cover the license application and the first two years of the license fee. We were licensed, with two years to prove we belonged.
Pay attention to which exam Arizona makes you sit. Not just the trade one. The business management one. The state understands something the industry does not talk about much, which is that construction companies almost never fail at the craft. In more than thirty years in this trade I have watched good companies with excellent tradesmen close their doors, and it was the business that failed every time, not the work.
So when you get a low number from one person working out of a truck, understand what you are actually looking at. He may be an outstanding craftsman. I have worked alongside tradesmen whose work I could not match. What he is carrying is sales, estimating, ordering, scheduling, production, billing, collections and warranty, all of it, alone. That is not a character problem. It is a capacity problem, and it produces the same two outcomes almost every time. He disappears from your project to chase the next sale, because the next sale is the only thing keeping the lights on. And the number was too low to begin with, because nobody was tracking whether it covered overhead.
One more thing worth knowing before you read another advertisement. To hold an Arizona contractor license you must carry a bond. With the exception of workers compensation, the Registrar of Contractors does not require a contractor to carry insurance in order to be licensed. So when an ad says licensed, bonded and insured, that is three claims and the state only stands behind two of them. Ask for the certificates. A company that has them will send them the same day.
Why does the lowest bid usually cost the most?
Because a bid comes in low when something has been left out. An incomplete scope, low material allowances, or a schedule that assumes nothing goes wrong. Those gaps do not disappear. They come back as change orders once the work has started and you are already committed, and the low number climbs past the realistic one you set aside.
We wrote a whole page on why the lowest bid costs more, including a short video, because it is the single most expensive decision a homeowner makes. If you are holding three proposals right now, read that one first.
