Reviews from San Francisco Bay Area Customers

"After seeing Sione's work at two neighbors, we contacted him to discuss a new stamped concrete driveway. Sione's was thorough, offered good suggestions and when he noticed things like the walkway was a bit dingy, and a downspout discharged water across the drive, he undergrounded the downspout water and power washed the walkway at no additional cost. He'll be back in 3 weeks to seal the drive, walkway and steps. Nice working with such a top-notch family business." - Lottie K.
"A very good friend of mine, Jobella B. had Sione do a large concrete job for her in Redwood City. She was extremely happy with the work done by Sione's Concrete. Her backyard looks like a dream park out of Sunset Magazine. Sione's Concrete Construction designed and built my backyard patio and retaining wall complete with all the required drainage facilities. The work was masterful and the complete job adds a great deal of value to my property. Sione is very knowledgeable about all aspects of concrete construction. His insight in laying out the concrete flat work is superb. I would highly recommend him to anyone who wants a first class job at a reasonable price." - Phillip L Gaal.
"I used Sione's Concrete for concrete wok in my backyard during my pool construction. Sione did the pool deck, patios and walkways. He also helped with the design, pattern and the color of the surfaces. The work was done excellently and exceeded my expectations. Not only did Sione and his team did everything quick and clean, but also helped me with protecting the concrete at no extra charge. Sione is honest and very professional. I highly recommend him." - Serge P.
