What reviewers praise
Dramatically lower quotes vs. competitors: quoted $1,500 for pipe descaling that another large company quoted $12,000 for — saving one customer $10,500.
1 cited review
“Another larger plumbing service quoted us at $6000 to descale, plus another $6000 to fix a separate issue. We called Legendary for a second opinion and they quoted us at $1500 -- we were thrilled! Frank, our first technician, walked us through the issue and was patient and thorough.”
Holiday and weekend emergency response — gas leak resolved over July 4th holiday weekend; was the only company of 6 that answered with a live person.
1 cited review
“Joe and Sean were amazing to deal with and get our gas leak resolved. Super quick service over the holiday weekend. I called 6 companies and they were the only to answer with person. A+++ all around, will be calling again when we need help!”
Technicians put customer needs over billing: Frank diagnosed a water heater issue as wind coming down an oversized chimney and directed the customer to fix that rather than billing for a repair that wasn't needed.

“Frank came out to get my water heater going again on a windy day. Saved me a lot of money by directing me to correct the root of my problem. Wind coming down an oversized chimney. Steered me in the right direction. Felt good that he put my needs ahead of a billable repair. Thanks Frank”

“Ben and Dylan installed our new water heater and softener, and fixed our badly installed water pipes. They were tidy and professional, and helped us understand the new equipment and how to take care of it. Overall a great experience and highly recommend them! Looking forward to working with Legendary on all our plumbing and HVAC needs.”
“We recently ran into an issue with some soft clogs in our plumbing due to excessive scaling in our older cast iron pipes under the house. Another larger plumbing service quoted us at $6000 to descale, plus another $6000 to fix a separate issue. We called Legendary for a second opinion and they quoted us at $1500 -- we were thrilled!
