The company completed the install of a Four Seasons room addition to our house on August 12, 2020. Since the install, we have had numerous leaks which resulted in wood damage, and in some areas rotted wood was covered over without replacing. First on August 18th, our flooring installers exposed the water barrier membrane around the perimeter of the room to begin the tiling, which revealed soaking wet, rotting wood. This wood is 32 years old from when the original sunroom was built and it supports the entire room. In my opinion, for $100 in wood this should have been replaced. ( tiling is cancelled the first time) On August 21, the production manager came out to look at the damage. He cut out a piece of the wood which showed considerable rot on the top and the bottom of the wood.. He said exactly "that the wood still has some meat to it" and the solution was to take down the room and replace the rotted wood, which he said they have no intention of doing. Apparently water got trapped under the water shield barrier around the perimeter of the room as it was exposed to the elements for a week or so during the rebuild process. No real explanation was given as to why this happened other than its very unusual, and we were told to run fans and a dehumidifier. I am just hopeful that its integrity hasn't been compromised and that we don't have issues down the road,The most recent leak became apparent on September 4, 2020 after a heavy rain, which has caused further delays to our construction schedule ( had to cancel tiling again). As there were new water stains around a wrapped wooden support beam, we decided to remove the metal to see where the water is coming from. The beam was completely rotted and soaked and we found out that each time it rains the metal wrap around the beam had disguised the leak. It was so deteriorated that you could put your hand through it. I had to hire a contractor to replace it immediately as I feared the structural integrity was compromised. Now we are on standby, waiting for the company to respond , have someone come and repair the room to eliminate the leaks. Meanwhile our floor installer, electrician, painter, and carpenter is kept in limbo. We have sent several emails, texts and left voice messages for the owner and the production manager and have received no response for 4 days now.
