Red flag
Owner estimated 8 man-hours for gas leak repair completed in 1 hour by 2 men; refused to charge for actual time and threatened customer — 1 of 5 analyzed reviews documents this
“Run Away! For a simple gas leak repair they estimated 8 man hours to complete the job. It only took 1 hour for two men. Owner was unwilling to charge for the actual time it took for the repair. The owner said "don't pay for it of you don't want to, and I will do what I have to do" Poor customer service and shoddy business practice. DO NOT USE THIS COMPANY!!!”
Red flag
Two separate reviewers report dishonest business practices and inability to complete committed jobs — 'NOT HONEST' and 'NOT DEPENDABLE' cited directly
“I called to set up two gas line repairs with Mario in February 2019. He came out and met with my maintenance team and gave us a quote and a start date. That date changed more times than I can count. The weather is understandable but his business practices are NOT. This company is obviously not equipped to handle the job they came out and bid.”
