Serenity Decks

Our deck was installed in 2016 with a 2 year warranty. Overall they did a descent job. However, good thing we were home at the time, as they installed one entire section of our deck incorrectly. They had to remove and rebuild that section to correct. That mistake left numerous holes in the brickwork, which they later filled the holes but we received NO compensation. After 1 year, the deck lights (over 16) that was recommended as a nice to have, we paid for them, but then stopped working. Several calls were made to send someone to figure out why they were not working and after many delays, somebody finally showed, they looked at it and then left. That was it, nothing else was done and now late fall arrived and they could not do anything. Our 2 year warranty has gone past and to this date, the lights are still not working. These lights were not a special order type deal as they are readily sold at the big box hardware stores.
It is now 2020, we still are no further ahead then 2 years ago. Also we have noticed that when winter is upon us, the joints in our steps seem to expand and small gaps appear, where the boards are joined. We were told composite products are far more superior than cedar and one would not really have this issue. Well it doesn't seem to be true at least in our case. See photo of gap joints when the cold weather arrives. The joints are not touching even after the warmer weather arrives.
Bottom line, a lot of money was paid for our deck but the company failed to stand by their warranty and service follow up.
