"Fair pricing and exceptional workmanship. Highly satisfied with the service."

"Great experience. Arrived during a holiday weekend to assess a leaky water heater. Friendly, personable, and kept me in the loop with what needed to be done, along with options. Work completed the same day, and I will be hiring them again for upcoming projects."

"Very talented with a remarkable skill set to remodel kitchen and bathrooms."

"Another plumber charged over $4k and said it would be another $31k to dig up my front yard and replace a sewer line. I think I was being conned! Geoff showed up quickly, fixed it easily and the cost was about $1.5k. Tenants are happy, I'm happy, Geoff is a superhero!"
