I have a 3 year old house and my walk-in door to my garage had, yes had a Pine 2X8 non-treated rough opening on concrete block. Rough opening and wood door frame has rotted. I have obtained a Vinyl door frame kit and I am wondering the correct procedure to install the new Treated Wood rough opening to the concrete block?

Thank You

I use "Red Head" sleeve anchors for block and wedge anchors for concrete. How was the old frame attached?

Attached with concrete nails to the block was 1-2X6 on each side of the door frame (regular Pine) and the door frame attached to these. There wasn't anything between the wood and block so the wood wicked the moisture from the block. I now have the vinyl door frame kit, but would like to know the proper way to go about this new frame installation? Do I use Treated wood, do I put a barrier between the block and the wood? My carpentry skills from 1-10 is 8. Please help, never did this one before.

I would definitely use treated lumber. If you have a relatively solid surface to attach the treated 2X6 to... use some type of concrete anchor. I wouldn't recommend concrete nails, though. If you use a "red Head" type anchor, you'll probably have to counter sink them so that they won't interfere with your installation.

Treated 3/4 Board Or What Ever You Have Room For, Attach Those First With The Outside Edge Minus The Thickness Of Your Brick Molding. Or If You Want The Door To Be Recessed More Just Move The Strips Back More. Attach Them With Tap Coms Or Ram Set Nails. Then Just Set The Door As Normal, Plum The Hinge Side First Check The Margins And Nail It Up, I Like Using Screws On The Hinge Side When Possible
