Service Description

At The Plaster & Masonry Advisory Co., LLC, we specialize in moisture diagnostics and building envelope analysis for historic structures. Moisture is one of the most common — and most misunderstood — causes of deterioration in older buildings. Our services help identify the sources of water infiltration, diagnose underlying failures, and develop solutions that protect both the structure and its historic finishes. We perform detailed onsite investigations using a combination of visual assessment, moisture readings, infrared imaging (as applicable), and field experience to trace moisture movement through walls, roofs, foundations, and exterior systems. Our evaluations document not only the symptoms — such as staining, plaster failure, or efflorescence — but also the contributing causes, whether they involve drainage issues, failed sealants, roofing details, or improper prior repairs. Unlike many general inspectors, our team understands how moisture interacts with traditional materials like lime plaster, historic masonry, and original stucco systems. We assess the building as a complete envelope, considering both interior and exterior factors that may be contributing to ongoing issues. Following our investigation, we provide clear, actionable reports outlining sources of moisture, areas of concern, and appropriate repair or mitigation recommendations. Our approach prioritizes long-term preservation, avoiding quick-fix solutions that may worsen conditions over time. Our Moisture Diagnostics & Building Envelope services give owners, architects, and municipalities the knowledge they need to protect historic structures from progressive moisture-related damage.
