I need non-standard replacement deck boards
I need to replace 5 boards in my deck but I'm having trouble finding the right size. They are 5/4 (1") thick by 5 1/4" wide X 8' long Douglas fir outside wood. I believe the deck was constructed about 15 years ago. I have heard that this size was sold back then to save cost, but they are no longer produced. This is a large deck in good condition, it would be very costly to re-plank it with 2 X 6. Any suggestions will be appreciated. I can rip boards and plane them. The problem would be the weather proofing. Working pressure treated lumber would be too toxic.
