"Am starting this review for this contractor as he partially finished the job with the promise to be back in two weeks to address the remaining cosmetic clean-up and seeding. I will finish reviewing the quality of his work in greater details when he comes back to complete the job started and update on the overall quality of his workmanship.
Roots from a tree had damaged the sewer line of my 1949 house. Needless to say, it was not pleasant. I called five contractors and everyone (with the exception of 1) quoted similar estimates for the job. I chose Knock Your Plumb Out Plumbing because reading the reviews in Angie's List, talking to a reference, and partially because Johnathan (the owner) was proactive in his communication with me. He was efficient-visited my house, called the city to get a better idea of my sewer line and the city's, identified that a water line may have to be replaced since the sewer line is beneath it, gave me a quote--all within a span of a few hours. He then followed-up. I was initially taken aback on how assertive he was, but in retrospect, it was what made Johnathan stood out amongst the other 4 contractors I called. Once I screened Johnathan, my husband took over the details in communicating with Jonathan while updating me. My husband and I were quite concerned initially when we read the negative reviews that Jonathan did not come back to finish the job; however, Jonathan was open and willing to discuss our concerns. He seemed upfront and a straight shooter, which my husband typically appreciates.
Once the contract was signed, Jonathan called to set up a day to begin the job. Due to several raining days this past week, the work was delayed by a couple of days. Jonathan and his crew worked all day to hand-dig the yard and completed the job by the evening. My husband checked in twice throughout the day. Our yard looks horrible right now, but Johnathan reassures us that I will look better. He will come back to complete the job in two weeks and seed the yard for grass. I will become back to finish up this review. Thus far though, Johnathan is very professional. His quote is within the range of other contractors' (although he gives a lifetime warranty-not sure whose life's or how we can enforce that though :))! He is very communicative and will update you on the progress. He didn't pick up my phone call but did pick up for my husband on the day he was working. If all goes well, I will definitely recommend Knock Your Plumb Out Plumbing to other friends in the city and will use him again for other works. Will be back to update this review. The rating of B for "overall" and "quality" are not reflective of the work per say but as the work is not completed yet, it will have to be a B right now.

"We needed to replace a toilet, James went with us to Home Depot to select one. We now have a water efficient and higher seated toilet, which is great for aging relatives that can’t bend so easily anymore. I would definitely hire/contract him again!"

"Mr. Fama had not remembered or written down the appointment time and so came to my house before I got home. Once that was straightened out, he worked very hard to remove my old stubborn faucet and installed my new one. He made sure that it was installed correctly and there were no leaks."

"Excellent, prompt, professional service at a fair and competitive price. Josh is a real gentleman who came out promptly after first contact and quickly turned-around a detailed estimate. Katlyn and Lyndsey in the office were fast, efficient, and clear with communications. Dan, Chuck, and Wayne were hard-workers who took great care and pride in their work and made certain it was right, and they were simply nice guys too. The Pohlman folks are our new go to plumbing professionals."

"Pablo arrived a little later than the appointment time, but he was polite and professional, and still completed the project on time. The tub looks amazing, the caulk is perfect. There is some residue left on the bronze piping that I can't wash off yet without damaging the glaze. I'm hoping it's easy to clean up. He did put up a protective sheet to protect the house, it probably would have been worthwhile if he also covered the shower hardware. I wasn't expecting the exhaust tube to run through the house to the front door, but he said the bathroom window was too close. It made sense when I saw the equipment, it was just unexpected. He laid down a cloth to protect the wood floors. All in all, good service, good price, and I would hire again."

"We recently purchased our Townhouse and it required some plumbing repairs. As we are new to the area, we didn't know any plumbers. So I took a long shot and used Angie's List which provided Drain Pro Services. I couldn't be any happier with the service, professionalism and timeliness of Patrick. He showed up at the time specified, replaced a toilet and sump pump and provided some additional plumbing repairs. His fee was more than fair and reasonable and he was respectful of our house used "booties" and totally cleaned up after himself. His magnetic business card is on my refrigeratior and I'm a Drain Pro Service customer for life!"

"After calling four plumbers to service what we thought was a major drain leak (overflowing tub, flowing down to our main level ceiling), Fred called back shortly after I initially reached out and left a message with one of his staff members. He wanted to know, in detail, what was going on and would stop to interject and to ask me questions to ensure that he understood the plumbing challenge. He asked if we would be home for awhile. I said 'yes', and he said, "I'm really close to your address, we'll be over there shortly to check this out." They were prompt, courteous, and he took the time to troubleshoot and to decipher that it wasn't a plumbing or drain problem; it was a washer/dryer problem. He suggested next steps; part of the equation was having an appliance repair professional out to fix the problem. He asked me to call him back and let him know what the challenge was. I asked what I could pay him and he said, "Nothing at all." My husband and I were floored! For someone who went out of their way to help us and to not write up a bill in return made our day. He was solutions oriented, he was thorough, and he was so compassionate. He just really cared about our challenge and wanted to ensure that it was taken care of. We'd call him again in a heartbeat!
