The Team

Preston Lemanski


Preston Lemanski’s experience in construction spans nearly two decades. His involvement in the painting business led him to form Lemanski Construction after he regularly hired subcontractors to perform various construction projects in the homes of his painting customers. Following more than a decade of increasingly expanding his business into a full-service residential construction company, Preston officially founded Lemanski Construction in 2015.  He has successfully managed and completed hundreds of construction projects in the public and private sectors, including commercial, residential, industrial, government, retail, educational, health care, and manufacturing. When he’s not working, Preston enjoys golfing, skiing, and spending time with his wife and two children.
