Ling and his crew was very professional through the entire project. We found them by friend recommendation who had a project with them 10 years ago. We checked the current status of friends backyard and thought it was by high quality so we decided to do our home with them. Plus they offered very competitive price as well. They first came to do the design and left us couple commercials to pick the bricks. All levels of product were available. The project started couple days late since they had to finish previous one as the homeowner added more todo. So Ling had to finish all that before mine, which I consider as a good thing that meaning they were not rush to finish but focus on quality and customer satisfaction. During my project everything was smooth. It was done fast and efficiently. Not cheap on material nor going with overpriced product either. Well balanced on project quality and money. They worked deliberately from 8am to 8pm for 4 days. The wokr include interlocking and retention wall. I also asked them to lay a 3 feet gravel path along the back of the house foundation for better drainage. Overall I am satisfy with everything. After the project while I needed something for the shed i was building they gave me freely and also revisited us to make sure everything was good. I will definitely recommend them for any yard project. I will found them next year to renovate my driveway and front yard for sure.
