Hi all, I am building a 10×10 shed, pressure-treated (ground contact grade) 4x4s sitting on pier blocks. I realized I didn’t use any separation between the concrete block and the sitting 4×4. Do you think I should take it apart and add a sill seal between? I know I have already gone ahead with the process but I don’t mind taking it apart to have it done properly Thanks in advance. Simone

The framing is PT and it looks like you will have plenty of venting underneath, so it's hard to see how moisture from the blocks will be an issue. We've installed several decks in wet areas (under a hot tub, next to a pool, etc.) with the PT frame resting on a stack of pavers without seeing an issue. Just keep the framing clear of the soil.
Adding a sill seal between the pressure-treated 4x4s and the concrete pier blocks in your 10x10 shed is a wise consideration for long-term durability. While you've already proceeded with the construction, the benefits of a sill seal, such as preventing moisture transfer and enhancing the overall stability of the structure, make it a valuable addition. Disassembling the structure to incorporate the sill seal would ensure proper installation and adherence to construction best practices. This proactive step can help protect the wood from ground moisture, minimizing the risk of decay and potential structural issues over time. Although it involves extra effort, the long-term benefits in terms of structural integrity and longevity make it a worthwhile investment in the quality of your shed.
Hey Simone, don't stress too much about it! Adding a sill seal sounds like a good idea to prevent any potential issues down the line, especially since you're using pressure-treated wood.
Taking it apart might seem like a hassle now, but it's probably worth it for the long-term durability of your shed. Plus, you'll have peace of mind knowing it's done properly. If you're up for it, go for it!
Thank you!! Which would you use between flashing tape and foam seal to separate? I have them both but not sure what's best.
If it were me, I'd say better safe than sorry, you know? Taking it apart might be a pain, but it's worth it for peace of mind. Plus, doing it right from the get-go saves you trouble down the road.
