I contacted Drainage and Erosion Solutions via email, asking for an estimate for some work prior to installing a fence in our backyard. Within a day or so, David Arias contacted me and was able to come out shortly thereafter. We walked around the property together, discussed a few options, and then he spent some time outside taking pictures and measurements. After about 30 minutes, he knocked on the front door and provided a written estimate. He then showed my wife and myself some pictures of previous jobs, basically identifying potential options that we might want to consider. Although his estimate seemed very price competitive, we were waiting for another estimate to come in, so we thanked him and told him we'd get back to him. In the intervening period, David took the initiative to email me with a reference for a fence company as I had mentioned in passing that we were still searching for a fencing company within our budget. After receiving other estimates which were 20-30 percent higher than this one, we contacted David on a Friday to let him know that we were ready to proceed. I asked about deposit payment, etc, but he advised that as mine was a small job, I could just pay after the work was complete. At first he was not able to give us a definite start date, but after some back and forth ultimately contacted me a week later, saying that his crew would be there on Monday. The day of the job, David showed up just before 8 am with eight workers (two crews). Not all of them were there the entire day, but there was always someone present who was clearly in charge and was able to communicate with me to tell me what was going on, what steps were completed and which remained, etc. David left after explaining the job to the crews (with me present), but returned in the early afternoon to check on his workers. With the exception of one phone call that I made to him to double check on how he was going to dispose of the leftover soil, there were no issues with the work. The workers worked consistently, were careful in how they dug, and I eventually left them in the afternoon to finish the job without my constant hovering. My wife returned home around 530 pm to find them just finishing up; they knocked on the door to tell her they were done. Later that evening I walked the property and noticed that in addition to the contracted work, the work crew had added mulch to some of my front flower beds -- which I appreciated. So did my neighbors -- they saw me outside and immediately commented on how nice of a job the workers had done. As agreed beforehand, David returned the following day so that we could walk through all of the work and ensure it was done to my satisfaction. David's boss, Mark Lane, was also present at the final walkthrough and it seemed like he often checks up on the projects to make sure the customers are satisfied. We again walked around the property before I handed them a check. All in all, this was a very smooth job. David had good ideas, they were price competitive (in fact, the cheapest of the bids I got), and their work was of high quality. I plan to hire them again for the front yard.
