All hardwood shutters are glued and dowelled together, the same as the high-end furniture. We have customers that have had shutters in their homes for over 35 years and they still look great. For the home, we recommend Basswood and hardwood shutters because of their durability. We build any shape and size right here in the San Fernando Valley. We are located at 15950 Blythe St., Van Nuys, CA 91406.
