As a premier national building envelope consultant, JEC specializes in evaluating and improving the performance of commercial, multifamily, and residential building enclosure systems. Our core services include roof and wall assessments, waterproofing and air barrier inspections, new construction QA/QC, water intrusion forensic investigations, diagnostic testing, thermal imaging, and Property Condition Assessments (PCA/Due Diligence) for long-term property management and acquisitions nationwide.

We provide building envelope consulting for a diverse portfolio of properties, including commercial facilities, multifamily developments, and residential buildings across the country. Our national client base consists of builders, architects, HOAs, property managers, commercial real estate investors, and homeowners seeking authoritative expertise in building sciences and enclosure performance.

The building envelope (or enclosure) is the physical separator between the conditioned interior and the unconditioned exterior of a building, comprising roofs, walls, windows, doors, and waterproofing systems. A high-performing building envelope is critical because it prevents water intrusion, controls air leakage, maximizes HVAC energy efficiency, and safeguards the long-term structural integrity of the property.

JEC provides nationwide forensic investigation services for complex water intrusion issues. We utilize a scientifically rigorous approach combining visual assessments, advanced moisture mapping, infrared (IR) thermography, standardized spray testing (AAMA/ASTM methods), and targeted destructive testing. This allows us to pinpoint the exact source of active leaks and deliver clear, actionable remediation protocols.

Yes. We conduct specialized spray rack testing following strict AAMA and ASTM standards to verify the installation and performance of windows, curtain walls, and sliding glass doors. This diagnostic testing identifies water intrusion pathways early, making it invaluable for new construction quality assurance, warranty claims, and resolving forensic leak investigations.

We offer comprehensive third-party building envelope oversight for new construction projects nationwide. Our services span from pre-construction design reviews of waterproofing details to on-site quality assurance (QA/QC) verification of envelope components during installation. This proactive approach significantly reduces contractor risk, prevents catastrophic moisture failures, and ensures the enclosure is constructed right the first time.

Infrared (IR) thermography is a non-destructive diagnostic tool that detects thermal anomalies across building materials. Our certified consultants use IR imaging to identify hidden trapped moisture in roofing systems, missing cavity insulation, and uncontrolled air leakage pathways that are invisible to the naked eye, allowing for accurate assessments without unnecessary demolition.

Yes, we provide whole-building blower door testing to quantify airtightness and detect specific air leakage pathways. This diagnostic service is critical for verifying compliance with stringent energy codes, optimizing HVAC system performance, and confirming that the building envelope meets the architect's design specifications for air barrier continuity.

We deliver objective, third-party roof and exterior damage assessments for insurance purposes, including specialized evaluations for hail, wind, and severe weather events. Our comprehensive forensic reports equip property owners, adjusters, and contractors with the factual data needed to make informed claim and repair decisions.

Our building envelope reports are definitive, photo-documented, and highly actionable. We clearly identify existing deficiencies, explain the underlying root causes of failure, prioritize necessary repairs based on urgency, and provide detailed maintenance or remediation strategies. This empowers facility managers and property owners to accurately budget, plan capital expenditures, and extend the lifecycle of their building assets.

You can request a consultation by visiting the "Contact Us" page on our website. One of our senior consultants will review your project scope, discuss your specific building performance challenges, and promptly provide a tailored proposal or schedule an on-site evaluation anywhere in the country.

Hiring an independent building envelope consultant directly mitigates the immense financial risks associated with construction, where enclosure defects account for over 50% of construction defect litigation. By providing expert design reviews and rigorous performance testing, we ensure that all exterior enclosure elements are seamlessly integrated. As objective third-party experts, we protect your real estate investment by identifying vulnerabilities before they become liabilities, minimizing costly future rework.
