Just months ago, after much delay, the men employed by the contractor I hired to gut renovate the small bathroom in my 4th floor Manhattan walk-up, feeling the job to be completed to their satisfaction, packed up and I moved in. Within a few weeks it was clear that there existed a major issue with the grout work outside of the shower and along a lower section of one of the shower walls, as well as a few other places. The grout in-between the ceramic tiles on the bathroom floor outside of the shower had already begun, in the most trafficked area, to chip loose and crumble. Along the bottom row of tiles in the shower, which had been replaced after I had discovered an error to the pitch of the shower floor, the contractor had been required to re-fabricate and install a properly pitched replacement pan and re-tile. While the new pan was pitched to allow for reasonable drainage, the individual that had re-tiled either didn't properly grout the bottom row of wall tiles, or used some sort of caulk, as the grout line was falling inwards with the consistency of wet putty within the first week.
Knowing the state of the bathroom I inherited, with warped floors and chipped tiles, I was looking for a proper solution and not a stopgap. I contacted a few individuals of which Peter and Steve were first to respond. The next day Peter came to the apartment assessed the situation.
Peter felt that the person addressing the shower pan must have caulked the walls and that the state of the floors outside the shower were likely due to the contractor having used wall grout for the entire job, rather than sanded grout for the floors. The latter was confirmed when I retrieved the remaining grout from my closet, which was indeed wall grout and the only grout that I had seen on-site.
The issue, with regards to the estimate, was whether the tiles had simply been improperly placed on cement board or if they were sitting directly on plywood. I knew that in the renovation they had gone down to the subfloor and sistered a joist, but could not say that they had built back up from there properly. Peter used a hammer to lightly tap on a few of the tiles in the damaged area, finding that certain tiles produced a hollow sound compared to others. He explained that this was caused by those particular tiles not being properly bonded to the surface below, be it cement board or plywood. If the surface below was plywood and needed to be replaced it would be a two day job, if not it would be a one day job, for either scenario it was a flat rate plus materials. With my permission he removed one of the looser tiles in order to determine if we were dealing with the former or the latter. As it turned out, there was cement board underneath, but the thinset that had bonded the tile to the cement board was mixed too dry and broken down.
Satisfied that I had received a proper diagnosis from an individual that knew his field, and with the understanding that Peter and his partner Steve do all the work they contract themselves, I was happy to go forward and contract them to do work the following week. Peter wasn't sure whether it would be the following Tuesday or Wednesday, so he phoned the next day and locked in the date.
The day of the work, Peter and Steve arrived promptly and commenced with the repairs. They were affable, conscientious, and personable. They found what had been expected and finished up by the late afternoon, working within my co-op's parameters of 9am to 5pm. When they decided a tile was better replaced, they did so using the surplus I had left over from the renovation.
It's now been a few weeks since Peter and Steve did the work and I haven't seen a single sign of the previous issues. I have confidence that the situation had been properly diagnosed and the repairs carried out with great competency. I would not hesitate to contact them if the need were to arise, whether to address repair issues or new construction. As I have found, the renovating a bathroom requires skill sets from a number of disciplines. Unless you know who the contractor you hire intends to use, and their background in the specific areas to be seen to, you best go with a tradesman whose line of business directly addresses the matter at hand.
