About this episode
Dan Barger shares his journey of growing Apollo Plumbing to $8 million in annual revenue, highlighting key lessons learned along the way.
For almost fifteen years, Dan Barger grew Apollo Plumbing the hard way — no price book, no P&L, no real read on his margins. His financial reporting system was opening the bank account and hoping. Today, Apollo does $8 million a year in residential plumbing. What changed? On this episode of The Successful Contractor, host Bob Houchin sits down with Dan — owner of Apollo Plumbing in Marysville, Washington — for the honest version of a twenty-year run. You’ll hear: Why a broken water heater turned Dan into a 20-year plumber. The moment Dan realized his “financial reporting system” was costing him money. Why 60–70% of Apollo’s marketing spend goes to radio — and what it buys. The comp model Apollo switched to last year — and what it did to close rates. The one thing Dan wishes he’d done seven years sooner. Where Dan’s taking Apollo next. If you’re running a contracting company, Dan’s story will sound uncomfortably familiar — and hopeful.
