Decks and Outdoor Spaces Built for a Short Season

Wisconsin summers are too good to spend inside. We build decks, platforms and outdoor spaces engineered for frost depth, snow load and a lot of freeze-thaw.

Built for Frost

Deck failures in this region almost always trace back to footings that weren't set below frost depth. The deck heaves in the first hard winter, and the ledger pulls away from the house.

We set footings to depth, flash the ledger properly, and use the right fasteners and hardware. A deck attached wrong to a house is both a structural and a water problem.

"3 brothers construction came out and built us a great hot tub platform. Pressure treated wood and concrete screws vs a more expensive concrete repour for leveling. Very professional and worked quickly. Thanks 3 brothers."

Common Questions

Composite or wood?

Composite costs more upfront and needs almost no maintenance. Pressure-treated is cheaper but needs staining and sealing every few years. We'll price both.

Do I need a permit?

Usually, especially for attached decks and anything over a certain height. We handle it.

When can you build?

Spring through fall for most work; footings require workable ground.

Can you repair my existing deck?

Yes — reframing, reboarding, railing replacement or full rebuild depending on condition.
