"My residential construction project was abruptly put on hold when a city inspector required a survey to verify the property boundaries. Unfortunately good surveyors are in high demand (at least 4 weeks out), and Voorheis and Voorheis was no exception. However, after discussing my job with Jeff, he thought he'd be able to work it in very soon between other clients. Jeff patiently answered my questions, and I ultimately felt confident to hire them for the survey. I was really happy with their thoroughness and professionalism, and ultimately the city inspector was satisfied and approved our setbacks. Thanks to Voorheis and Voorheis for getting my project quickly back on track with their excellent and timely work!"
