We restore buildings. To functionality. To high performance. To grandeur.

At Klein & Hoffman, we work collaboratively to deliver value-driven architectural restoration and structural engineering solutions. Innovative yet practical, we listen to you, develop creative solutions and find ways to go from “no” to yes.”

Since 1953, we have worked with building owners, campus and facility managers, condominium association boards and architectural firms, putting our client’s best interests at the forefront. Pragmatic and practical, we push the envelope while being mindful of budgets, consistently delivering superior results in high-rise buildings, campus environments, condo buildings and famous landmarks, including the Shedd Aquarium, O’Hare International Airport and Loyola University. If you are in the Chicago or Philadelphia areas, call on—and count on—Klein & Hoffman.


When I put a team together, they need to understand they’re part of the team. We all work together. Klein & Hoffman has become part of that team.”

“At Klein & Hoffman, they’re not afraid to look at things a little differently.”

“They’re cooperative, easy to work with and very thorough. It has been a very good relationship.”

“The guys I work with are easy to get a hold of. They prioritize me and my needs and they meet timeline expectations.”

“They’re value engineers and they’re better at it than most.”
