We started Cornerstone in a garage off Plaza Drive in 2011 — a journeyman plumber, a HVAC tech, and a promise that you’d always see the same friendly face at your door. Twelve years later we’re still family-owned, still running ten trucks across Iredell and Mecklenburg, and still answering the phone ourselves. When something breaks in your home, we treat it like it broke in ours.
“Brian was at my house within 90 minutes on a Saturday when our water heater gave out. Fair price, clean work, and he even hauled the old one away. Lifesavers.”
— Karen M., Mooresville“Replaced our 18-year-old AC. Quote was $2k less than a big-name competitor and the install crew was immaculate. Highly recommend.”
— Dave R., Cornelius“I’ve used Cornerstone for three different homes now. Honest pricing, no upsell theater. They’re just a good local company.”
