"AJB Construction did a great job. Workers were knowable in all areas of the work performed. Work site was cleaned up at the end of each day, project was started and completed as proposed. I would highly recommend AJB for any concrete or block work needed."

"Our experience with Green Republic Landscapes was outstanding! From the moment we contacted the company we were greeted with friendly voices and deep understanding. Motti, and his team are highly knowledgeable, creative, and professional! Their attention to detail and ability to execute their plan was above what we imagined. We felt listened to and understood! Motti ensured that he talked us through each step of the process and touched base constantly before moving on to the next step. We searched and shopped around and found that Green Repulic Lanscapes pricing is the best one on the market for all they offer and create. If you are looking for landscape professional call Green Republic Landscapes. Ohad & Shirly Bendavid"

"I hired Dalinghaus Construction to install two push Piers for a freestanding column/wall (bad clay soil causing movement). I meet with Kevin to go over the scope of work and he explained everything in detail. The price was the best I can find. Took one extra day to finish the work, but they did not charge me any additional fees. 3 month later, I had a feeling that the column/wall is moving again and call Kevin. He show up in a few days and show me there is no way that wall is still moving and he was right. They are very good at what they do and customer service is the best. Thank you very much."

"Bob Warren was simply terrific, i had a great experience consulting on my crawl space. Really, Ive never had a crawl space and while having one in my first home i did not know what to look for that was in need of repair. Bob did a thorough job looking over it for me and very honestly delivered me feedback. Turns out i am not in a dire need of repairs but when i do, i know who to turn to. Thank you Bob, and GroundWorks for the professionalism"

"Robert was outstanding! He?s a great communicator - and was attentive to our needs throughout the project. Over three mornings, he removed portions of our old back patio, repaired parts of the remaining concrete, then coordinating and finished the replacement of concrete for a slightly smaller patio. He made sure everything was completed in a timely manner, managed some cost adjustments and made sure to keep the area clean and organized. Exactly what we asked for! We would hire him again!"
