Semco products are defective and they do not stand behind their windows and doors. The customer service department is a joke.... in response to my recent email they said that the glass in their windows is not covered in the warranty. We built a custom home valued at over 1 million dollars about 20 years ago using Semco windows. After about 5 years the windows started to spontaneously crack in various areas of the house and in all seasons. Obviously this is a defect of some kind involving the integrity of their product. Throughout the years we have contacted their customer service department with no satisfaction. Presently we have 3 windows that are broken. It is very costly to replace them and we are not currently in a position to continue on this path. We are thinking that the seals are not sound as evidenced by 2 other reviews on their FB page indicating similar problems. It is only common sense that the history of our situation is not normal...who has 11 windows explode without explanation if they are not defective? We chose their product thinking they were of good quality and had a decent warranty. The windows were very expensive and we never expected to experience this type of failure of their product. We have owned 6 homes previously with much less expensive windows and have never heard of such an issue. BUYER BEWARE...DO NOT EVER CONSIDER USING ANY PRODUCTS FROM THIS COMPANY !YOU WILL BE SORELY DISAPPOINTED AND BROKE REPLACING THEIR DEFECTIVE WINDOWS AND DOORS. My email is teeberman@yahoo.com if you would like more information about our horrific experience. read more
