I'd give SIX stars if I could. Prompt service. Professional staff. Bought a house in YLP. New rebuild. Possessed by gremlins. Its been one problem after another. Our septic system had been rigged to limp across the finish line to clear home inspection. Sub standard pump (Harbor Freight special) questionable wiring, missing parts, etc. "Jim the Jedi" (technician) came out, diagnosed the issues, replaced the parts, and got us not only in compliance, but got the system operating better than when we bought the property. Thanks Jim, your awesomeness knows no bounds!

Response from the owner

Thank you so much for sharing your experience, Frank. It means a lot to hear how much you appreciated the prompt service and professionalism from our team, especially Jim. Navigating unexpected challenges with a new home can be stressful, and we're grateful for the opportunity to assist. Your kind words about Jim's expertise and dedication will certainly be shared with him.
