That rotating post showcase right under the navigation really needs to have the text looked at. Even on the easiest to read ones I had to work too hard at it. Get some more contrast in there. Lightening up the text would be an easy way to do that. On your post titles, you need to either capitalize things title style or don't. "Why Decks and Fences need to be maintained!" should be "Why Decks and Fences Need to be Maintained!" to match the capitalization you're using with the rest of the post titles.
The logo which you have created looks good, but you wants any suggestions or idea regarding decks check this site: www.sierrastructures.com
