Landmark Inspection Services, LLCLandmark experience · Since 1998
Inspection experience matters when it helps you understand a condition, assess the record and identify the next step. Landmark brings that perspective to housing programs, home inspections and construction assignments.
For attorneys · Expert-witness experience
When a housing inspection is at issue, counsel needs a clear understanding of what the record establishes: what was observed, which requirements applied at the time, who held each responsibility and what follow-up was documented.
Sean Umlauf brings practical Housing Quality Standards (HQS) inspection experience to that analysis. His documented expert-witness assignments include reviewing inspection records, court materials, deposition testimony, program requirements and administrative plans to prepare detailed written expert opinions.
For attorneys evaluating an inspection matter, that experience offers a focused perspective on inspection practices, housing program responsibilities and the documented sequence of events.
