Carpentry & Joinery

Clicking/creaking joists

I got my kitchen floor retiled May last year. It had been done 18 months previously but the builder made some errors resulting in cracked tiles. The subfloor wasn't secured very well. To cut a long story short we got the floor redone, this time by a professional tiler. He was fully aware of what happened previously and said he would assess the subfloor before making a call on wether him and his partner could strengthen it themselves or get a carpenter to come and do it. They did it themselves and sent me pictures to show all the additional noggins, and screws the applied. In January I got back from my holiday and noticed that where the tile meets the stairs in the hallway (which is part of the same floor) there was a crack in the grout. I've since established it's likely to be because of two different materials meeting (tile and wood) and that grout should be raked out and replaced with silicone. This weekend, I noticed a sound which I can only describe as a click (or like what I hear when I walk on the wooden floors in my livingroom) when I walked in a certain area of the kitchen floor. Please note this is around 1.5/2m away from the cracked grout next to the stairs. Every time I walk in this area I can hear the sound, so far there is no evidence of cracked grout or tiles. The floor is made up of joists, 18mm ply, ditra and porcelain tile. Any insight would be greatly appreciated. I'm rather worried given the previous problems I've had. Thanks in advance. Nat
