One recent customer said Poseidon installed an 8-zone irrigation system, that the owner was present for the entire installation, and that they took care of everything, including plumbing and electrical work. A recent customer called Bob a knowledgeable irrigation system designer and said the job involved removing a previous, non-functional system, at a price they felt was fair. At the quote meeting, a recent customer said, Bob promised "You won't be able to tell we were here upon completion of install," and that turned out to be true. A recent customer with a large property said Poseidon has taken care of it for about four years and is responsive when there is an emergency leak. A recent customer who asked for an estimate on a new irrigation system said it listed no equipment and no zone count, that the owner, Bob, arrived almost an hour late to discuss it, and that the office later wrote that the company had no time to install that fall and was booked for spring. That customer called the estimate overpriced and gave the job to a company that came in significantly less. A 2025 customer said they were one of the first customers of owner Bob Koteles and had used Poseidon since building their house more than 11 years earlier, including a lighting install. A 2024 customer said Bob had honored warranty work. A 2022 customer said Bob installed their irrigation system, then a complex uplighting system for trees, walls and walkways the next year, and removed trees as well. A 2022 customer said Bob had done irrigation installation, landscaping, home repairs, lawn care, seasonal mulching, leaf cleanups, foundation painting and snow removal for them.
