Good reminder about the ledger board—it's easy to overlook. I usually do a quick visual check each spring, but honestly, I haven't been as thorough underneath as I probably should be. Last year, I found some rot near the stairs that looked perfectly fine from above. Makes me wonder if anyone here has tried sealing or treating the underside of their deck to prevent moisture buildup...worth the effort or not really necessary?
I've actually sealed the underside of my deck before—mostly because I had leftover eco-friendly sealant from another project. Honestly, it wasn't too hard: cleaned it first, let it dry, then brushed on the sealant. Seems to help with moisture, but jury's still out on long-term effectiveness...
Good call on sealing underneath—most folks skip that step. Did you notice any difference with insects or mold afterward? I've debated doing mine, but wasn't sure if it'd really make a noticeable impact long-term...
