Our HOA manager recommended CPI when our toilet overflowed on a Saturday evening in July. They picked up the phone at 8:30pm on a Saturday night. One of their plumbers showed up 30 minutes later. He quickly determined that the clog was a bigger issue further down the sewer line which required a professional hydro jetting cleaning to resolve. After checking with the HOA manager, CPI sent a jetter machine and another plumber within half an hour. Their crew worked until 11:30pm to clear the clog. We were so happy that we could use the bathroom again! CPI was responsive, communicated well, worked fast, and resolved the issue during off-hours. We will definitely call them again.
Hattie C.Yelp review
CPI has again done a top-rate job of storm season preparation for our complex, video inspections and hydrojetting all the drain lines and sewer lines too. They work hard and efficiently. Especially appreciated their extra effort to finish up before the Thanksgiving holiday with all the friends and family gatherings— Luis took a moment as he was finishing up and gathering up his equipment to say all looked good with a sewer line that had been questionable and that we should be good now for all those big holiday get-togethers.
Lucinda C.Yelp review
CPI and Alex were extremely helpful when our local church’s water heater kept malfunctioning and needed replacing. From the initial diagnosis, explanation and recommendation of replacement, we always felt that our needs were being tailored to. Not only were they extremely kind, knowledgeable and professional, but they also were diligent and efficient during their time.
We’re truly grateful for their excellent work and would highly recommend CPI to anyone in need of plumbing or heating services, especially for those in larger community buildings like churches like ours.
