What's the most economical way to add insulation to my attic. I have a 25 year old condo with about 1400 sf. I had a guy from the power company come out and give me an energy analysis and he says I'm fine - but I find that hard to believe since I can see the flooring in places in my attic. I'm pretty sure I need more insulation (my neighbor agrees) and I'd like some input about which type would be most economical -- blown or batts. I've read that blown is the least costly product but batts are easier to install and require less time (less labor cost) (is this true??), so would that balance out and justify installing the batts? I live in S. Fla. (zone 2) and I don't intend to do this myself -- I hate going to the attic - it's just too dang hot up there! I pity the guy who does this for a living! I wonder if they charge less labor if it's done in the cooler months! Your suggestions are greatly appreciated!

Hi, I have a 4x6 beam in my crawlspace that is supported by a 2x6 ledger board secured to a foundation wall by fasteners that appear to be large nails with fender washers. Unfortunately this tight dirt crawlspace has been subjected to standing water for years and I am worried these fasteners have become compromised by corrosion. I was thinking of boring through the ledger board and into the wall so I could insert ½” threaded rod and epoxy them into the wall. I would then secure the ledger board with ½” washers and nuts. Is this a proper approach, or is there a better method. Thanks for taking the time to read my post and consider my questions.
