Project was initiated in February of 2015. The contract was signed and deposit cheque cashed in two days. The town wanted site specific engineering done, which was, but only after the company's engineer came back from a two month vacation. The permit was issued in late spring of 2015, the build started in late September. The roof was the first thing to go up. It looked great. The roof crew didn't bring the railing, that was purchased in the contract, so a different pair of installers came two weekends later. They installed the railing well enough but also took it upon themselves to add in a lot of wood structure under my deck that was contrary to what the engineering demanded. I had to remove all the material under the deck that they put in so I could install the material in the proper manner that their engineers told me that I had to put in. Glass next: One solid glass wall came and a modified sliding glass wall came. The first problem was the sliding wall. It was supposed to fold. I was told that the type of folding wall now only comes from Finland and will be a six week delivery. Now we fight over the cost. The next problem was the third wall that they forgot to build. They just forgot. This would result in another four week delay. It was December of 2015 by the time this project was complete. It wasn't done but it was complete. It started to leak in various places and fast forward to late 2017, it doesn't leak now. More than ten times they came back to repair the leaks and more than ten times it still leaked. We have met almost all of Lumon's installers and knew 5 salesmen that the project was handed off to. The original salesman has "left the company." My last contact with Lumon was a text to the salesman in charge at the time to let him know that the roof is still leaking. He was to have gotten back to me in two days. It is now the end of November and I have not heard a peep from Lumon. In August of this year, I rented a brake and bought aluminum to re flash the roof. The roof doesn't leak now, but not because they fixed the problem they created for me. It is really important to know that you need to be really handy to own this product. Good luck.
