"Completed quickly and very knowledgeable plumber."

"Extremely satisfied.  Company was responsive (My initial call to them was on Xmas Day when I noticed the sewer backed up in my back yard).  They called me back immediately and  agreed to send someone to look at it the next day (after ansering some questions, we agreed it was not an emergency) - they came the next day as promised and even called prior to their arrival.  The plumber assessed the situation and took pictures to send back to Larry.  I spoke with him and agreed to have them come back on Monday when the equipment  needed to address would be available (needed an extra long hose and camera set up given the location of the cleanout cup).  Each time dealt with the company (Larry) he would call to let me know status and options.  On the day they came, Larry and his associate were at my home at the time promised.  Spent nearly 3 hours and all is well.  So although a bit pricey, well worth it given the responsiveness and professionalism of the company.  Would highly recommend them for any of your plumbing needs.

"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."

"I am very pleased with the service. The job was done quickly and everything was done professional."

"Went well. I thought that I might need a new trap or elbow since water was leaking. As it turned out, it was the sprayer that was leaking and not the elbow. The tech did not try to oversell me all new plumbing and I appreciate that."

"Oct. 6 2025 it went quick. I received an estimate of The job first. The work was done correctly. It didn't take long. If I need plumbing service again. I would contact Cassidy plumbing & Heating."
