"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"I recently hired G&L Design Building and Landscape for a major outdoor project, and I couldn't be more thrilled with the results! From start to finish, the experience was seamless, professional, and truly impressive. Dror, the owner, is a visionary. His attention to detail, creativity, and commitment to quality were evident in every phase of the project. He took the time to understand my vision and brought it to life even better than I imagined. His team built a stunning retaining wall, installed lush, vibrant turf, and laid down beautiful interlocking pavers that completely transformed the space. On top of that, they planted an incredible selection of trees and flowers that added the perfect finishing touch—absolutely breathtaking! The crew was punctual, respectful, and worked with great care and precision. It’s rare to find a team so dedicated and passionate about their craft. If you're looking for top-tier landscaping and design, look no further than G&L Design. Dror and his team are the real deal—professional, talented, and a pleasure to work with. Highly recommended!"

"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"KN Remodeling redid my floors, removed a wall and got my JADU permitted, plus many more random fixes. Whatever project I threw at Nathan and his team he got done. They were great and I would use them again."

"Encore builders did a fantastic job transforming an ugly hillside into a terraced wonderland of gorgeous flowering plants. Brandon was so professional and knowledgeable and continually came by to monitor progress on this large project. He continually conferred with his fabulous crew who worked diligently and meticulously to make this now glorious hillside a master class in expert masonry and engineering. Bravo Encore Builders. A truly Five Star experience."
