Front entry door - frame is beginning to rot after just 3 years.
I purchased a Mastercraft entry door with 2 sidelights from Menards 3 years ago. The center mull piece has deteriorated and softened at the bottom where it meets the sill. I contacted the help center via email regarding "lifetime warranty" and was told I did not caulk the door properly. I was disappointed in this response - that because I did not leave a big, unsightly bead of caulk they say the door was not caulked properly, so they refused to honor the warranty. Buyer beware, the material used to manufacture this door frame is below average and should not be deteriorating to the point of softening after such a short time.
