We are very happy with John. His Grout Solution company does great work at a reasonable cost. Very reliable. We actually left the keys and went away on vacation. The shower floor was retiled with great results (no more standing water in the shower). Old crumbling grout was replaced on the whole bath floor. We spoke to other contractors, but one failed to show up, and the other promised to follow up with the work and keep canceling. Great experience with Grout Solutions.
