I could not have asked or received better service from Victor and his team over at CPI plumbing. What I appreciated most was the honesty and professionalism. CPI was able to show me the exact problems with my piping, including photos and full explanations about why I was experiencing drainage problems. They didn’t cut any corners on the job, and it only took them a day to completely overhaul the piping in my 100 year old house. The cost was upfront and at no point did they try to upsell or shill other services. It was incredibly relieving working with them, knowing all of the problems they were going to fix, how they were going to fix them, and the cost of the project all up front. I will be calling them for service for years to come, and wouldn’t hesitate to recommend them to my friends and neighbors.

I was most grateful for the fast, next day response to my request to hook up a new washing machine for my renter two days before Christmas.My tenants comfort is very important to me, and at this time of year it would be hard to wash clothes and dry them.The two young plumbers who came out were very kind and pleasant. I am sorry I can't remember their names. my belated thanks for a great service.

They were at neighbor's house fixing a broken pipe and when I asked if they could replace a kitchen sink they agreed to do the job. It was far more involved than originally thought but they got it accomplished with a lot of work and know how. Very satisfied!

I called CPI on a Friday and they were able to take care of my issue on Monday, which was much appreciated.Trevor was wonderful, showed up on time, took a photo of the burst pipe with a large hole in it, located under the house and was able to fix in a very timely manner.

Trever was prompt and courteous. The repair he did in the well house appears well done and as we had agreed. He also performed a walk thru to verify no additional issues with possible frozen plumbing in the house. At this point all appears good! Thank you!

We had a pipe burst and remembered that we had used CPI for our water heater in the past and immediately called them. The rep I spoke with very helpful and got us an appointment for Jan 1st. The rep then called back and said they had an appointment available for Dec 31st between 12 and 4pm! Our plumber Trever then called to let us know when he would be here. Trever was very professional. He explained our options along with the price differences, and let us know what the different options would entail. Trever made sure we were comfortable with the option and got to work right away. When he was finished, Trever once again made sure that we were happy with our choice. I am keeping CPI as my plumber from now on and hope to have Trever and CPI out for our next plumbing project.

Our tech, Aaron was awesome. Our 2 year old furnace quit working during snow and very cold temperatures. He arrived on schedule andquickly found the problem and advised us how to fix it. Aaron was careful about wearing booties trying not to bring snow into our home. Very polite and well spoken. This is the 2nd time CPI has saved us, and was able to come out on the same day both times. Highly recommend CPI and Aaron!

Jon came out on one of the coldest days of the year and repaired a leaking pipe in my unheated basement after a holiday weekend snowstorm. Despite the icy roads, he still made it on time and completed the repair in a very timely manner. Thank you!

Excellent service. Our gas fired water heater started leaking recently. Due to their positive reputation, we called CPI for urgent replacement of the tank for a household of four. CPI arrived at our home as scheduled and Brannigan and Wes immediately began tank replacement work.It was obvious that the two were very knowledgeable with the equipment and process needed to successfully replace the tank. I'm the type of person who asks a lot of questions. Brannigan and Wes were very patient, professional and courteous in handling and replacement of our water heater and by evening our home was back to normal.Again, my thanks to CPI and Technician Brannigan. I will be calling them again for any future needs and will recommend CPI to anyone with plumbing and HVAC repair or replacement needs.- Don & Sue Ney.

Davis with CPI performed a diagnostic assessment on my heating system and corrected the problem he found in a timely manner. He arrived on time and was professional. He advised me in advance the cost of the service and it was fair. He has worked on my heating system previously. He is very knowledgeable. I will only call CPI in the future.

CPI Plumbing were very responsive and helpful in every step of the way as we dealt with no hot water, no water softener and eventually needing a whole new hot water heater. Wes was especially great and worked hard all day to get us hot water back. Thank you Wes, Stephen and the whole CPI crew!

CPI PLUMBING provided excellent service from Lizzy in customer service to Davis and Jackson in repair and installation. All employees were polite, kind and efficient. We are very pleased with CPI in every area. We signed up to members for their general maintenance as well.

Winnie Floyd

Aaron showed up to fix a problem with our toilet. He was extremely courteous and explained CPI’s pricing and gave me an estimate, I felt the price was to high and decided to tackle it myself. Aaron called his supervisor to let them know that I had declined service and they told him not to charge me for the call-out since he was already on his way back to the shop from another job. The problem was fairly easy for me to handle this time but I do want to thank Aaron and CPI for their very fair treatment.Corky Culver

I can't say enough about how responsive CPI and Jose were in taking care of a pretty dire situation - a leak in our sewer line running up to the street. They understood we needed help right away, and Jose was there within 2 hours. We couldn't be happier with their service.

Your technician Steven Olsen was prompt ,courteous and very helpful in explaining the problem with my heater which is 20 years old and outdated. Bad heat exchanger . It was at that time we talked about all the options and decided to have a new heater and thermostat installed . Steven was very patient and thorough through the process of inspection and my new heater options. We are looking forward to the installation of the new heater .Well done .. Thank you , Bill Marsh

Brannigan and his crew did a great job replacing an old galvanized water main. While it initially seemed like a straight-forward repair, rocky soil complicated the trenching. Nonetheless, they worked extra to get it done. After that, the actual installation went smoothly and quickly. The trench was neatly backfilled and all extraneous material was cleaned up. A first class job. I highly recommend them.
