EXCELLENT Based on 3 reviews Lou H.2025-01-23Verified U&R came through for us multiple times getting our residential land survey done for home remodeling. Their response time was SO much faster than other providers I contacted -- AND -- when we hit a bump in our permitting process and needed an additional item the City never mentioned (setback certificate), they squeezed us in the very next day so we could keep our construction timeline going. Lifesavers, I tell you. Very professional and great product (the survey) as well. Baohong S.2023-04-03Verified Theo is a Great licensed land Surveyor. He is very knowledgeable in his field and he loves his job. I find there are different reports and numbers for my house lot sizes are. I try to get a new land survey report before my house is listed for sale. I appreciate that Theo can come to my house quickly to give me a quote promptly. Even I decide not to do it this time since it may take months for any change for county recording processing, I have learned some useful information from meeting with Theo. Theo presents his working company well. After talking with Theo, I can feel this company is a good company to work with if I need land survey service in the future! Thank you very much, Theo! Mark A.2021-11-09Verified Chris & Anthony were incredibly helpful in securing a quick & comprehensive land survey needed to keep moving along in a permitting process. Chris quickly responded on a Friday afternoon, talked through different options to be speedy, but comprehensive and cost efficient for our needs. He helped move the project along quickly having Adam come out and do land surveying work, then keep me updated frequently on the status of the final survey report. He then worked directly with FEMA to file a LOMR and complete any additional city follow-up questions we had. Highly recommend this company!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
