Chad was very genuine and a pleasant to talk with, straight forward, honest with the options we had as far as upgrading to a better system. Ultimately we chose the path that was more affordable for us and he was perfectly fine with that and jumped right into it and completed the entire job on a timely bases. Extremely happy with the service. Thanks Chad
Jake came by on time and was extremely efficient. Also an extremely nice guy
Travis & Rafael were very prompt & professional & very personable. Travis helped with the thermostat functioning & gave me a full explanation of everything with the installation.
Both Jake and David were very knowledgeable in all aspects of their professional plumbing duties. Would highly recommend Cornell’s Plumbing for all your plumbing needs. Reasonably priced as well 👍👍
We had the pleasure of having Adrian A. as our technician to service our home today. He was extremely thorough and explained each step of installing the new waterline for us. We were so pleased with the work he performed and the high level of customer service that we received from him. We will be recommending him to all of our neighbors!
Ed arrived on time for our appointment and begin the installation and did not stop until the furnace was installed. I would not hesitate to recommend Ed or his company for any purchase or installation of HVAC equipment.
Samuel and Venamin worked for 12 hours installing our new gas furnace, heat pump and thermostat. They were respectful of our home and when finished everything was cleaned up. They showed us each piece of equipment we purchased, items we needed to be aware of, and asked if we had any questions and answered all of…
Nathan was fast and efficient and did an amazing job installing a new sink/vanity/faucet and new toilet. Super fast and it looks great. The old vanity was hideous so this bring joy to my heart.
John, with the help of his apprentice, did an excellent job putting in a new shower pan and valve for me today. They definitely met the extremely high standards that I have come to expect from 20+ years of having Cornel do my plumbing jobs as a general contractor. Fantastic service, clean up, and professionalism.…
I’d never hired Cornel’s prior to the unfortunate events that unfolded in early October: a different contractor severed our water supply line, triggering gushing and puddling water, a frantic and chaotic search for the street shut-off valve (which was buried in dirt), and then a hasty Google search for local…
We've had a leaky toilet, a backed up laundry drain/tub and finally just said do a complete re-pipe/redrain for a 42 yr old home. Here is report card- Office Staff: Amazing Owner: Amazing Re-drain crew: Amazing Customer Service: Amazing Pricing: Competitive and Reasonable (Never scary) Scheduling: Super fast (sign…
Brenden was super friendly, explained everything so we knew our options and got the job done quickly. Recommend!
Cornels is fantastic, they have done multiple jobs at my home including plumbing and installing a new AC/Heat combo. Joe is an amazing, friendly plumber! He fit right in with the family, was great to our pets and completed the job promptly. Ask for Joe if you can!
Ed and Jace just finished installing a new furnace, heat pump and air conditioning unit for us. They were super professional and great to work with. Very nice guys and were very informative and worked hard. Thank you!
Joe and Brenden were prompt, professional, and really went the extra mile for me with the plumbing repairs that I needed. Highly recommended.
Cornel's replaced our old, galvanized pipes in our basement and utility room; installed a new, larger water service; and replaced the old cast iron waste line. They were very helpful and professional and did an excellent job. Their licensed plumber, John, and his assistant Josh were polite and responsive,…
Juan, Nate and another technician (whose name suddenly skipped me) came to our house on 9/11/25. They installed 4 faucets, 2 toilets and 2 valves within a day. Amazing job! They were courteous, professional and came well prepared. I highly recommend Cornel's Plumbing!
Cornel repiped our entire home. Ernest, John and James were professional, knowledgeable and respectful of our house and specific needs. Highly recommend Cornel plumbing!
Great overall experience! We replaced our 20+ year old HVAC with a new system they recommended. We had multiple phone calls and a home walk-through before deciding on what would be the best option, and they were very patient and thorough answering all of our questions to ensure we chose the right solution for our…
