I paid them to unclog my drain and they did great he was here for about 20 minutes and boom done and gave me a 5 year warranty then BAM 3 Months later it was clogged again so I called them and they sent the same guy out again and he stuck the thing in just like before left it for about a minute and said he can't get it unclogged and him and the manager proceeded to tell me they need to dig up my yard and driveway for $3,900 to fix it.I said no and they left I went in and stuck a water hose in the clean out turned on the water and BAM ALL CLEAR. DIG UP MY DRIVEWAY I THINK NOT..HORRIBLE SERVICE AND WON'T HONOR THE WARRANTY
