"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

"We went with Elizabeth Shutters because they are made in the USA and lead time was much less than anyone else. Cost was about in the middle of the others we received quotes on. We were very excited to get our shutters installed. Mike the installer was on time and professional. The issue is the actual quality of the shutters. We only had 5 windows done and every shutter has some type of mark from scratches, chips, gouges and even paint rolling down one. Most of the issues were on the frames but some on the actual shutters. We also were having a shade installed but the bracket was not correct. Things happen and I even understand some issues with product. My complaint is that I reached out to Elizabeth Shutters exactly 1 week ago today. Told them of the quality issues and sent pictures. Also commented that pictures are hard to see everything and I was hopeful someone would come out and look. I also asked when the bracket would be in for the shades. Again 1 week ago and I have heard nothing back. That is not acceptable."

"Amazing! Enrique was quick, communicative, easy to work with, the work is beautiful, too! Am looking for other projects for which to hire him and his team. He worked clean and orderly, too."

"In 2018 we hired Todd and his team to replace a multi-story wooden deck at the rear of our house, a very challenging project that ended up exceeding all of our expectations. We recently had a second child and needed to remodel the lower story of our split level house in Oakland in order to make the space more usable, and luckily we were able to hire Todd again during a break between other jobs. The project ended up being much bigger than we initially thought, but Todd was just as professional, honest and communicative as he had been during our previous project and provided updated cost estimates as we added more scope to the project. His two-man team of experienced carpenters, Forrest and Osman, were a pleasure to work with again and were on site every day to coordinate the small army of subcontractors (insulation, stucco, electricians, plumbers) who worked on the house. Forrest and Osman's craftsmanship is truly impressive and they always went the extra mile to accommodate our requests. Our new living space is a dream come true, and we're very happy that we had the opportunity to work with Todd again. I'd recommend T James Construction for any home improvement project."
