Hello. If I built my house, I would still do it myself. To design, or rather tell what I want - I can. But construction work is not for me. I am in my house, which I bought a few years ago, I do a little. I usually turn to specialists for help. Recently, I had to do the basement wall crack repair . He tried to figure it out, but in the end he still called them and called the master. It is better to pay, but to be sure that the work is done as it should. And for me they would definitely have to redo.
