HMM GC Inc. was built on a simple idea: homeowners in the Bay Area deserve a contractor who shows up, communicates clearly, and delivers work they're proud to live in. With a background that spans hands-on construction and real estate, we bring a perspective most contractors can't offer. We understand how a well-planned remodel affects not just your daily life, but the long-term value of your property.

Our founder started in the trades and never left. Over the years, that field experience grew into a full general contracting practice, with a particular focus on detailed remodels and thoughtfully designed home additions. The real estate side came naturally. When you understand how buyers evaluate a home, you make smarter decisions about where to invest during a remodel.

We work across San Francisco, San Mateo, Palo Alto, Menlo Park, Mountain View, Portola Valley, Woodside, and Atherton. These are communities with high standards, and we hold our work to match. Whether a project is a kitchen overhaul in Menlo Park or an ADU build in Portola Valley, we treat every job with the same level of care.

Our services cover the full scope of residential construction. We handle home remodels, kitchen and bathroom remodels, ADU builds, home additions, framing, finish work, trim installation, door installation, and window installation. That range matters because it means one point of contact from rough framing through the final coat of paint.

Clear communication is not a bonus here. It's part of how we work. You'll know what's happening on your project, when it's happening, and why. If something changes, we tell you directly. That kind of honesty is what keeps clients coming back and referring their neighbors.

When our founder isn't on a job site, you'll find him with his rescue dogs. It's a small detail, but it says something real: a good home should feel lived in, warm, and full of life. That's what we're building toward on every project.

HMM and Hector did an outstanding job building me an ADU, from dealing with Palo Alto inspectors and permits to work quality. Communication was also outstanding. I’m very happy and have used them again for smaller jobs on the main house. Highly recommend!

Hector was easy to work with from start to finish. He kept the project on schedule, stayed on budget, and communicated well throughout the entire process. The quality of work was excellent, and I would definitely recommend him to anyone looking for a reliable contractor.

HMM and the entire crew were fantastic to work with! They transformed our small half bath into a beautiful full bathroom, and the entire process was smooth from start to finish. The team was professional, communicative, stayed on budget, and the quality of the work exceeded our expectations. We’re so thankful for everything they did and wouldn’t hesitate to use HMM again for future projects. Highly recommend!

We recently remodeled our old dated downstairs bathroom with HMM. They brought thoughtful design ideas, did high quality work, and were professional from start to finish. Their subs were also excellent. The end result is a beautiful bathroom we’re really happy with, and we’d gladly work with HMM again. Thanks!
