I worked with OCG on several issues at my property, from roof and window leak troubleshooting and repairs to plumbing inspection, clogs. This team is very responsive, I see estimates come through quickly without having badger them after weeks of nothing. The estimate details are specific and the pricing is competitive, which is nice to see when you're trying to figure where this money is being spent. My in-laws and friends as well have used them for interior renovations and have had a similar experiences.Thanks for all the work you guys do! Look forward to future projects.

As a paint contractor, I have worked with Luis and his wonderful wife Isabel on multiple projects throughout the Bay Area. Their service is always timely, their proposals are consistently in a very competitive range, and the quality of work is top-notch.

If you need a reliable all-in-one licensed construction firm for your home, you can count on Optimum Construction. From start to finish, they were a pleasure to do business with. We had them take care of a bathroom remodel, interior house painting, hanging new doors, and replacing all the floor jacks in the crawl space. They also completed a lot of other smaller home repairs and saved us from a ridiculous expense from another contractor during an emergency plumbing repair. I highly recommend them if you need a jack-of-all-trades construction firm to handle multiple projects. Double high fives to Isabel and Luis for their guidance and expertise!
