"Wicked Plumbing was very responsive in comparison to other plumbers I had called during a weekend emergency. Water was at the inch or so level in a three inch drip pan (with no overflow drain) for a leaking electric water heater. Nick was great to deal with and had the job completed in a short time period. Replace your water heater before this happens. It was a ten year old water heater (second floor condo). It could have been a disaster if someone wasn't around. Highly recommend!!"
