Client Testimonials


I have worked professionally, since 1989, with Mark Sauer Construction. I have always been impressed with their knowledge of the Secretary of the Interior’s Standards for Historic Preservation and their commitment to the client’s project. Our historic preservation clients are frequently not-for-profits or public institutions on extremely tight budgets; I highly value Mark Sauer’s ability to advise the client on the most effective use of the limited funds available.

We were so pleased with the work that Mark Sauer Construction did in repairing and restoring the roof rafter tails of the Mission Church that we contracted them to repair or replace the roof rafter tails of all of the other buildings on the Mission grounds. The competence and professionalism of everyone on Mark Sauer’s team are quite remarkable, as are their sense of cooperation and “can-do” attitude about any and all unexpected problems that surfaced during the project.

I am pleased to recommend Mark Sauer Construction for historic restoration projects–both large and small. The company recently did an outstanding job on the reconstruction of our wooden water tower and tank at Rancho Los Cerritos Historic Site. Mark and his men are highly skilled, efficient and professional; they enjoy the challenge of working on historic projects and clearly take pride in their work.

Mark Sauer’s knowledge, background, and experience over the past five years have been invaluable in restoring my three buildings in downtown Chino. No one should begin a restoration project without consulting MSC first.
