Guardian Water Services Review
Negatives
The majority of the negative feedback comes from a former employee who has had numerous issues with the company's account managers and engineers. They described the account managers as lazy and incompetent, often not visiting the site to survey the job requirements and making promises to clients that they cannot deliver. The engineers were also criticized, with some being described as lazy and lacking in competence. Additionally, the former employee felt that the higher-ups and office staff did not care about the employees, viewing them as just numbers rather than individuals.
Positives
On the other hand, there was a positive review from a property manager who has had a good experience with Guardian Water. They praised the team for their professionalism, quick response times, and ability to simplify complex technical situations. They also recommended the company and thanked Shaun Cunningham and his team for their work and support.
