“Faucet Replacement”

Roberto is so fantastic to work with. Super knowledgeable and friendly. Very professional and courteous. He moved my towels back under the sink neatly stacked after he was done working. It’s little things like that that motivate me to write the 5 star review. I’d recommend him for any plumbing job and I would call on him again in the future if we needed his services again.

“Water Heater Replace”

I had Red One Plumbing out for a separate issue (hot water heater replacement this time) and it just confirmed all of the positive aspects I experienced in the past. Roberto showed up on time, was transparent and informative through the entire process, and was able to complete the job the same day. Expectations met and exceeded once again!
