Although the doors were easy to assemble, I had some assistance from my handyman. They were also stained and poly-urethaned by my handyman. They look amazing. These doors look great and are of excellent quality. There were no problems with spacing, but it is important to ensure that the pieces are properly assembled. These doors have been used for several projects without any issues. However, we might have more experience in construction. Don't lean on the doors, as this could cause them to warp before installation.
