They do excellent work but a rather overpriced.
Marklein Plumbing had recently been out to my home to change out some bathroom fixtures. I had used them once before. The work turned out well, although I did feel a little bit gouged by the price. They are rather expensive. I have had other plumbing companies do work for me in the past and in making a comparison with Marklein Plumbing I still feel that they are very overpriced. The company does respond quickly though. So I guess you get what you pay for in that respect. I would probably recommend them but not certain if I would use them again myself due to the price.
