Building a deck is one of the most popular do-it-yourself projects. Unfortunately, not all decks are constructed soundly. Typical problems fall into three categories: the support posts and attachments, the railing and the decking boards.

A certified professional will inspect the deck as part of a general home inspection. The first thing the professional will do is verify that wood posts are in good condition without warp or major fracture and that they are securely attached to the structure. Masonry posts need to be checked for broken block or brick and deteriorating mortar joints.

The professional will check that railings are not rotting and are securely attached to the deck, stairs and house. The railings should not wobble back and forth and there should be no exposed nails. The inspector will also check the decking boards, regardless of the material used, to make sure they are not rotting or broken.
