I have contracted CE last year for a relatively small job. Unfortunately it seems that the company is set up for larger clients. While the sales and design services were good, the actual work crew was terrible. I am still finding shortcuts, leaks, and issues. The crew was unprofessional, dirty, left food leftovers all over the yard, did not clean up after the job and any request for fixing issues they created was met with: "we are not getting paid for this". So, I went to a reputable company to avoid having to be a project manager and yet ended up dealing with sub-sub-contractors directly. I have brought all this up directly with the company rep but there wasn't really a follow-up. The plants are mostly alive, hence the 2 stars instead of one.
