What to sort out first
Some repairs need no permit in Milwaukee’s suburbs: West Allis, for example, exempts swapping deck boards, stairs, guards or handrails on an existing deck. Movement at the ledger, beams or footings is a different job. Stay off a deck that moves and have a builder or inspector look at the structure first.
- Boards that flex or have rot
- A wobbly guard or stair
- Gaps at the ledger board
- Posts that have shifted or heaved

Deck Repair FAQ
Is this site the builder?
No. This site takes deck requests from Milwaukee-area homeowners and passes them to independent deck builders. You agree on price and scope with the builder directly, and a match is not guaranteed.
Can I replace boards without a permit?
In West Allis, yes: code section 13.05 exempts replacing deck boards, stairs, guards or handrails on an existing deck. Other cities differ, so check your own.
When is a repair really a rebuild?
When the ledger, beams or footings are failing. New boards on a bad frame do not fix it.
Do I need a permit?
It depends on the municipality. Milwaukee’s DNS checklist says a deck needs a permit. Waukesha, Wauwatosa and Brookfield also require one, and West Allis exempts only very small, low decks and like-for-like board, stair or railing replacement. Other suburbs set their own rules.
