Low quality works and very bad customer service after payments - We purchased a four seasons sunroom from Ambience Additions in 2014. After the sunroom was completed, we had a lot of leaks around the connection between the existing roof of the main house and the sun room. After calling the company's project manager several times, finally the original installer came who did a little and said that he is not a roofer and it is our own responsibility to get a roofer to fix it. Since we cannot get Ambience Additions to fix it, we found a roofer to patch it. Then, the next big rain storm came, we had leaking from the window seals and seals on the glasses. I called again. After many calls to the reception, project manager (Aaron O'neil) and the owner (David Donnelly), finally, David Donnelly sent a person to fix the leaks in 2015. Since 2015, every raining season, we had leaks from the joints of two roofs. We did not contact Ambience Additions as we knew that the owner will not take care of it based on our previous experience. Fortunately, in Southern California, we had not much of rain before 2018 winter. The first bad rain can on the night of December 7, 2018, and we found severe leaks all over the sun room on the morning of 12/8/2018 morning (Saturday). I called Ambience Additions on 12/10/2018 several times and cannot reach the reception, so I left a message. I called again on 12/11/2018, I finally reached the reception Heidi, and she asked me to send her photos to heidi@***.com, and she said that she will let the owner David Donnelly know. Since then, I called Heidi again and again, and I called the old mobile phone of Aron (reached Ted). Heidi kept saying that the engineering team still did not make a plan. Now is 1/15/2019. More severe leaks from the heavy rains. The leaks had damaged the floors covering also. Based on my experiences, I would recommend everybody be very very careful to do business with Ambience Additions and use the products from Four Seasons Sunroom.
