Bought two new exterior doors that were installed in the fall of 2015. Already after two years, the surface started to "bubble" in the middle of the door without any other visible damage. Contacted Skånska byggvaror but received a negative response that it was not something they took responsibility for. Now the doors are in such bad condition that it's time to replace them. I absolutely cannot recommend purchasing from Skånska byggvaror. They received photos six years ago and again this spring. An exterior door should last longer than 3-5 years. Yes, the doors have been waxed.
