"I was is a bad way. A little voice told me to check the cellar and found my hot water heater had kicked the bucket. Water everywhere I plugged in my need on home advisor and wicked plumbing called me immediately. They were at my house within hours and replaced everything. Quick, clean, polite, extremely fair pricing, a pleasure doing business with them. I highly recommend WICKED PLUMBING. GREAT JOB!!"

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."
