Hear Their Thoughts on CMS Plumbing!
    "He put on surgical booties before entering our home and both jobs were complete in about 20 mins!"

    On 11-08-19, we were experiencing issues with our two toilets. I called CMS and they said a plumber would come out between 2-3 pm. A young man named Sam showed up at approximately 2:20 pm, and I explained the issues. He put on surgical booties before entering our home and both jobs were complete in about 20 mins! He was extremely professional, left no mess and was done fast! I wish all service appointments went like this, thanks CMS!⭐️⭐️⭐️⭐️⭐️

    "So thank you Rommel and CMS plumbing, for being so honest and professional."

    Excellent service from beginning to end: receptionist was helpful and friendly; scheduling was prompt. I was expecting to have to replace the whole toilet system as it's 'old' and not flushing reliably. Rommel persuaded me my old WC is actually of higher quality than modern low-capacity models. So he saved me a bunch of money. All that was needed was cleaning out the calcium deposit that's been building up. After he finished and I said I'd like him to come back to deal with another issue he offered to look into it - a blocked shower head - there and then because "there's still 20 minutes on the clock so let's save you another call out!" And yes, he replaced a blocked pipe in 20 minutes. We had stopped using that shower because another plumber two years ago told us the whole thing had to be replaced and that involved cutting away sheet rock etc. So thank you Rommel and CMS plumbing, for being so honest and professional.⭐️⭐️⭐️⭐️⭐️
