BECS

What BECS does

BECS (Building Envelope Consultants & Scientists, LLC) is a U.S. building envelope and building science consulting firm headquartered in Baltimore, Maryland, founded in 2012. The firm provides end-to-end services spanning facade inspection, roofs/walls/windows evaluation, waterproofing assessment, building science performance analysis and testing, architectural design services with code and accessibility compliance, and consulting engineering including structural evaluation and expert witness work. Its underlying technology is human domain expertise applied through standardized process modules covering bidding, design, investigations and assessments, and quality assurance, rather than a proprietary software platform.

BECS generates revenue through project-based professional consulting fees and service contracts, delivered via a consultative enterprise sales motion directly to clients. Its customer base spans eight verticals: commercial, healthcare, higher education, historic preservation, multifamily residential, new construction, public sector, and religious structures. The firm has historically operated as a boutique provider emphasizing long-standing client relationships and personalized service, with the BECS Labs trademark supporting its branded building science offering.

In 2025, BECS was acquired by Lerch Bates, a multidisciplinary building consulting firm. As a result of the transaction, BECS's employees became employee-owners of Lerch Bates, and BECS now operates as a Lerch Bates company providing nationwide U.S. building science services with Total Building Performance capabilities. The acquisition is the firm's most significant structural change, transitioning it from an independent Mid-Atlantic boutique into a node of a larger national platform.
