Ivan L. says, "These reviews don't lie! I had the pleasure of working with Bar, Bar came to my home in Los Gatos to consult me for my new project where I'm converting my 400 square foot garage into an ADU. Professional, on time, punctual, kind, educated, and very polite. He sat down and whipped out a laptop and did something I have never seen. He redid all my plans for me and made them ten times better. He made 3D renderings for me to visualize his final product in my home. This company goes all out and gives major attention to detail. Not to mention impeccable follow up skills. I highly recommend them. Bar was incredible."See more

Joe N. says, "Fernando built a new external stairway for us and repaired an existing entryway into our garage. It involved adding two external doors in a confined space, blocking off an entryway for rodents, and increasing support for a header that was built incorrectly underneath a window and door. He and Beto were consistent in their work timing, thorough in their craftsmanship, and forthcoming when they encountered an unanticipated problem with an existing part of the house. They were also frugal in their use of materials and advised us when to choose better quality materials for durability, and when it was ok to cut down on costs by using reclaimed elements. In all, we are pleased with their work and will hire them again for our next project."See more

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

How do I hire the best general contractor in San Francisco?

First, conduct an online search for qualified general contractors in the San Francisco area. Take a few minutes to review their services and decide which contractors are best suited for you. For example, if you need some electrical work done, search for contractors who have completed electrical projects. If you can’t find enough information on their profiles, send the general contractors a message, read customer reviews and view past project photos.

You should also check to see if the contractor is properly licensed. For example, you can try looking for their license information on their profiles on the Contractors State License Board website. You can also ask the contractors to provide that information.

Finally, ask several contractors in San Francisco to send you free quotes so you can get an idea of how much it will cost to hire a general contractor.

What is the best waterproof flooring for a basement?

There are several great options for waterproof basement flooring. For example, epoxy floors are waterproof but are thicker and sturdier than paint. Make sure the concrete substrate has been prepared for application.

Tile is a designer’s dream, giving you a moisture-resistant surface that’s infinitely customizable. Rubber sheets or tiles are also good waterproof options, particularly for playrooms, workout areas or laundry rooms.

Vinyl tiles and planks imitate wood or other materials very convincingly, provide moisture resistance and last a long time. And sheet vinyl is affordable and a great waterproofing solution for those in need of quick fixes.
