The building envelope is comprised of the below-grade foundation walls, the exterior walls, windows, doors, roofing and flashing systems. A properly-designed and installed building envelope provides reliable and durable barriers to control water, air and moisture. Additionally, the building envelope plays a vital role in the health and longevity of a building. D.A. Doddridge & Associates, Inc. leverages our experience and training in investigating and identifying building envelope defects to develop defensible opinions, accurate remedial costs, building code violations and creative solutions for building envelope failures.
