San Francisco Homes Need More Support

Most residential foundations in San Francisco are decades old—and many weren’t built with today’s seismic risks in mind. If you’re seeing cracks,

sloping floors, or moisture intrusion, it may be time for a full replacement.

We apply commercial-level engineering and project management to residential foundation work—delivering durable results that

meet today’s strict codes.

“We approach every home like it’s a structural investment—not just a quick fix.”

Connor and his team completed our substantial renovation which involved a complete foundation replacement, an actual lift of the existing structure, complete interior demolition and replacement of 1 kitchen, 2 bathrooms and significant living space. Finished in 7 months which felt incredibly fast. Connor is incredibly knowledgeable, honest, and a straight shooter. The quality is high, and I could not him recommend more.

Connor was the GC for a complete remodel of our house, including the addition of a new floor which required foundation work, new grade beams, and shear walls for nearly half of the existing structure. His price was fair, and very close to the estimate. Connor was easy to communicate with, straightforward with information, quick to respond, and willing to listen to our needs in order to deliver a product we wanted. The project was quick relative to the enormous scope involved and met our expectations for how long we’d have to be out of the house. Don’t hesitate to contact Connor for a fair estimate or any questions about your project.

Connor Daly came highly recommended by my real estate attorney, and I found him to be extremely professional. During the initial walkthrough of my home, he carefully listened and answered my questions in clear and non-technical language. He returned calls promptly, and his employees were efficient and meticulous when it came to opening and closing parts of the house’s walls that the design engineer needed more physical details about. My family was fully ready to hire Connor’s company for our house’s seismic retrofit project, but an unexpected family development unfortunately changed our plans at the last moment. Nevertheless, I plan to recommend Connor Daly Construction to friends who need a seismic retrofit specialist.
