Called Sachse Plumbing this morning and spoke to Kenny, described toilet clogged up, recent foundation post leak check up indicated sewage leak so i thought this clog has something to do with the leak. Like must residents, we are leery trusting a plumber for something we cannot see under the slab. Kenny explained to me that they will first attempt to solve the problem, which is to unclog the toilet, if that does not work, they will expand further, he sent a plumber over within a few hours, he is professional, courteous, has all the equipment needed, fixed the issue within 30 mins, and ensure me that it is working fine and no heed to do extensive testing. Sachse plumbing is just 1/2 mile from me, I will always call them when I need help with plumbing issue. Their price is reasonable. Thank you Sachse Plumbing!
