How do you handle disputes over repair estimates due to tenant negligence?

[Charles Granja]

Hello everyone,

I'm seeking your input on a recent incident where a tenant caused a plumbing backup by using baby wipes. Upon discovering the issue, my management arranged for a company to address the problem. I had already engaged someone the day before, but they lacked the necessary equipment. The new company quoted $650 to jet the line. Given that my preferred plumber couldn't come until Tuesday and the tenant urgently needed access to the bathroom, I reluctantly chose the more expensive option. My preferred plumber would've charged $350 to jet the line.

Upon arriving 10-15 minutes after the job began, I confirmed my initial assessment of the blockage. To my surprise, the main technician mentioned a total cost of $1400 for their services that day, a figure significantly higher than the initially quoted amount. The discrepancy between their scheduler and the actual cost raises concerns, as I would not have agreed to pay $1400 for a 15-minute job, even if the cost is being forwarded to the tenant. 

In this situation, would you advocate for the tenant and refuse to pay the contractor the inflated price (only pay the agreed upon price), or simply move-on?

Looking forward to your insights.
