If you're thinking of a different size or shape for your new deck, it's a good idea to measure the existing deck as well as the back of the house before removing it. The measurements are helpful when comparing new deck designs and layouts.
Removing an existing deck can be dangerous work. This is especially true for elevated decks and severely rotted ones. As with any construction project, watch your step, obtain the right equipment and add additional supports and braces if necessary to prevent the deck from collapsing under it's own weight.
Permits for Replacing an Existing Deck
A big misconception when replacing a deck is that you do not need a deck permit. This is far from being the truth. Having an existing deck is no guarantee that the deck was legally built to begin with. Also, the deck that is there now may not be in compliance with current ordinances and town requirements for decks.
