1 cited review
“He replaced my water heater only a few hours after I called the office, the day before Thanksgiving. He was on time, efficient, friendly, and most of all, trustworthy. He also charged a very reasonable price. And rather than trying to sell me on a bunch of expensive upgrades I didn't need, he specifically advised against them.”

Honest pre-service triage: Todd walked a caller through diagnostic tests over the phone before dispatching — resulting in a no-problem trip that saved the customer an unnecessary replacement.

What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
1 Google review (1-star) documents a 60% cost overrun: written quote of $7,755 for sewer lining became a $12,555 final bill after company claimed pipe "too many twists and turns" and required $4,800 in additional access points.
“Quoted $7,755. Final bill: $12,555 — a 60% increase. We agreed to move forward with a sewer lining project based on a written quote for $7,755, which clearly described the scope, access points, and installation approach. After spending a half day attempting to place the liner, the company stated they could not proceed as quoted due to "too many twists and turns" in the pipe.”
Upsell-heavy sales process noted in 1 review (4-star) — office calls back with 3 tiered options and tried to upsell after selection; simple spigot job took 3 hours billed at $350.

“Simply awful. Horribly overpriced. Tried to upsell a $200 job to over $800 with unnecessary repairs. Slow (took over 3 hours), clunky process. Never again!”
Positive
“After two failed attempts from other plumbers to fix my leaky faucet, I finally found someone who could solve the problem! Hugo and Sam arrived half an hour earlier than expected and worked very hard for several hours making sure everything was done properly, thoroughly and with care. They actually replaced several things for me in all of the bathrooms in my house in addition to the leaking sink, and it feels very …”
“Hugo and the team at King is truly the best in the business!! Hugo is the hardest worker and is determined to over deliver excellence & doesn't stop until the job is done right. From full install bathroom remodels, water filtration systems and mold removal to emergency care on my house, I trust Hugo, Jeff the Owner, Robert at the Supervisor level and the amazing ladies who help direct your calls from the moment …”
