SUPPORT POSTS
SUPPORT POSTS
Support posts are the part of the structure you rarely see, until one fails. Years of water intrusion at the base of a wood post, or a corroding steel column, can compromise everything above it. We inspect, repair and replace support posts for decks, balconies and stairways, correcting the root moisture issue so it doesn’t happen again.
Best for: Any property where a deck, balcony or stairway’s support structure shows signs of failure.
