We had the folks from Poor John's re-pipe our old (built in 1937) two-story home. This involved extensive work in the basement as well as the second floor. A fair amount of the kitchen ceiling had to be opened up too. Rowdy, our plumber, is a master with Pex Pipe and carefully went about his work. Each night, he cleaned up before leaving. When the job was done, he covered the holes in the kitchen ceiling so that bits of plaster would not fall into the food preparation area. And, most important there were no leaks afterward, and we have like-new water pressure on the second floor. We had this job bid several times, and Poor John's was the most reasonable. I can't recommend them highly enough.
