“Kendall and GS plumbing did a great job! They were able to come out within a few hours of my call and had everything fixed the same day. Kendall was friendly and professional and was able to diagnose the problem quickly, provide a price to fix it right away, and get it fixed and working.”
“Jan 2026 - Update Had GS out to install a whole-house shut off. Unfortunately one of the fittings they used burst a few days later and damaged some of the flex ducting for my HVAC under the house. They came out the same day and fixed the burst pipe. THEN...they sent an HVAC company to replace the damaged ducking at no cost to me. One of few businesses that stands by their work.”
Stood behind a warranty failure: fitting burst a few days post-install; they came same day and also paid an HVAC company to replace damaged ducting at no cost.

workmanship=14 in 93 analyzed; Trevor crawled into crawl space to trace and isolate drain blockage rather than just clearing the nearest symptom.

“GS Plumbing provided outstanding service from start to finish. My technician, Trevor, arrived on time and was professional, courteous, and attentive as I explained the drainage issue I was experiencing. After verifying the problem, he first attempted to clear the line with a snake. When it became apparent that the blockage was likely farther down the line or more severe than initially expected, Trevor didn't hesitate to take the next step. He went into the crawl space beneath the house, carefully traced the line, and isolated the approximate location of the problem.”

The evidence — in reviewers' own words
Critical
“We had a ceiling light flickering in the garage. I opened it up and water poured out. The technician that showed up says it was condensation… in cold weather? It poured out. He was hung up on one test - “Does the water meter move when the water is turned off?”. He flushed the toilets and looked at the water meter. Charged us $151. I discovered five months later that the toilet above the light was leaking… …”
Positive
“Ben and his team did a great job diagnosing the plumbing leak source and were able to to replace the affected pipe section. The were timely and knowledgeable. I would definitely use them again.”
“GS is a top-notch outfit, supported by great people. Was a pleasure working with Lee and Cody… Trevor was our technician who single-handedly performed our hot water heater replacement, plumbing, and additional faucet installation. Great guy and very solid technical expertise. All in all, very pleased with GS plumbing!”
