We ordered a conservatory through Northern Tropic in late May 2016 and were told that installation would begin on Sept. 7. We thought that was a long wait but decided to go ahead and paid our deposit and put a planned vacation on hold. Sept came and went and we were told it would start in Oct. Oct came and went and we were told it would start Jan. 7. So we rescheduled our vacation for early March. Jan came and went and FINALLY construction started in late February (while we were on our vacation - exactly what we DIDN'T want!) and was completed in April, almost a year after we paid our deposit!! The final product was very high quality (but should be, given the price tag) but if you decide to go with this company, you may have to wait a long time, despite what you are told when your place your order.
