Looking to start another backyard project and needed to get a better idea of where the septic system reaches beyond the generic drawing from the health district. Darren came out at the time promised charged what he quoted and even answered some questions while giving some valuable advice. While I didn't price shop for the service I feel I received a good value for what I paid and now I probably won't see these guys for another 5 years, but they will be my first call in the future.
