The window rough-in must be lapped in a tough material like Bakor Blue Skin, which is then tied into the existing exterior membrane [e.g. Tyvek, building paper etc.] Once the window is inserted and fastened, all the exterior cladding must be replaced along with trim etc. From the inside, all wet areas [e.g. shower walls etc]. must use a waterproof or cementitious wall board [over your studs, insulation, and vapour barrier]. Then, I recommend a membrane like Schluter Ditra be installed [for tile zones], then grout, then tile.
Thank you for the excellent information. I have a very bad feeling about this whole thing. If the quality of what I see is any indication of what I don’t see, I’m afraid that I have serious trouble.
There was no permit-- something I don’t know how/when to address, either with him or directly with the city. (I assumed he was doing what was required and I didn’t ask.)
His contract states that he:
-Remove existing window ... and install new vinyl replace window and seal tight.
-Remove all tile and backer board and tile in tube area down to studs
-Install new cement board over same area where tile was removed.
-Install new tile over new cement board and grout.
It sounds like he:
-may or may not have tied the window into the existing exterior membrane, etc.
-did not fix the exterior
-did put in cement wall board (this I saw)
-may or may not have used a membrane under the tile
Does anything else stand out?
Bottom line: does it sound like I need to tear this down to see if it was done right, that means in essence, re-do the job? Do you suggest calling the building inspector?
I liked your suggestions about finding the contractor (and I know you couldn’t weed through the entire thread) but we have used this guys 3 times already. He sub-specialty is masonry and waterproofing so one would think he has a clue about water control? On paper he has the credentials, including a Construction Supervisor Liscense so it was logical to call him, but what a mistake!!! We were hasty to get water damage under control.....
