What causes a toilet to leak from the base when flushing?

The exact cause varies, so we confirm it on site using our Gold Star Diagnostic Protocol. We start with a full toilet and drain evaluation, then clear blockages with professional-grade augers or hydro-jetting if needed, and use camera inspections to pinpoint issues. Pricing is flat-rate and upfront. The diagnostic is $179 and waived with repair. If replacement is the best fix, typical installs run $750–$1,500+. We provide same-day and 24/7 help for overflowing toilets in Garden City, NY. <br/>
