"Our toilet in the master bedroom had been broken for 3 weeks. We have hired local Lowes to install but they were so bad and unresponsive. First a technician came with wrong model then another with wrong part, eventually just stopped responding completely. At the last minute, we also found out the toilet flange needed to be replaced. Again, Angi’s to the rescue and we found Augerpros. They responded fast and did the job very professionally. In 2 days since we started searching , our toilet was repaired annd new one installed. Cost was also reasonable compared to Lowes who had no customer service. Highly recommend."

"From first contact through the end, BlueFrom kept me informed, and kept their word. Mike was on time and on point. He was professional and courteous enough to answer my questions (even some I probably should have known). He took time to educate me on my tankless system, hard water, filtration, basic care and what will need to be done. Bottom line...fast, fair, honest...and I have hot water. Happy wife; happy life."

"For a diagnostic fee, Sam found the leak in my tankless water heater and replaced an o-ring, leaving me that day with a currently non-leaking water heater. I appreciate Sam's diligence and hard work."

"Experienced Staff! Raymond over the phone was amazing! The plumber that came to my house was Rick, highly recommend him! I had a water filtration and tankless water heater installed by this company and couldnâ t be happier with it. This was the second time iâ ve used this company , The first time was for a 3rd opinion on my hot water leak under the slab. Two well known large companyâ s in OC wanted to charge me $24,000-$31,000 for a repipe with no other options and said i had multiple leaks without pulling out a single tool!! Had this company out and right away Rick preformed a ultrasonic leak detection and found my leak (Only one i actually had) and provided me with a quote for a reroute of the hot water line and a quote for a repipe. Price was Very fair and saved me tens of thousands. Me, my family and friends will use this company for all of our needs going forward."

"The city called and said I had a sewer leak. They checked and thought it was a sprinkler problem. Checked my sprinkler system and then had the neighbor check his. Neighbor will be getting his repaired."

"Ironclad Plumbing gets my highest recommendation. Great employees and service. Ironclad has done a few small jobs for us in the past but recently they completed a really big job. Chris is very knowledgeable and kept us informed of discoveries and plans. Everyone on the job was professional and communicated constantly with us. They worked hard and were extremely efficient. This is a great company to work with."
