Deck Building in Minnesota

A deck is the one part of the house that lives outside all year. It takes sun, rain, snow load, freeze and thaw, and the ground underneath it moves every winter. Everything that decides whether it is still solid in fifteen years happens below the surface you walk on.

What We Build

New decks, and replacements for decks that have reached the end.

Composite decking for homeowners who would rather not spend a weekend every spring on maintenance. It does not need staining or sealing, it holds its color, and the better lines carry long manufacturer warranties.

Cedar and treated wood for homeowners who want the look and the lower build cost, and do not mind the upkeep that comes with it. Properly maintained, wood lasts a long time and looks superb doing it.

Railing systems, stairs and landings are part of the same conversation, because they are where a deck either feels finished or feels assembled.

The Parts You Never See

Footings go below the frost line. Minnesota ground lifts when it freezes, and a deck sitting on shallow footings gets pushed around until the framing racks, the boards gap and the connection to the house starts working loose. The depth is set by code, and there is no sensible way to shortcut it.

The ledger fastens the deck to your house. It carries a large share of the load and sits exactly where water runs down the wall. Almost every serious deck failure traces back to this board — wrong fasteners, or no flashing, or both. It is the first thing we look at on any existing deck, and the detail we are most careful about on a new one.

Flashing and fastening decide whether water gets behind the ledger and into the rim joist of your house. That is a repair that costs many times what the deck did.

None of this is visible once the decking goes down. That is exactly why it is worth asking any contractor how they handle it.

Rebuild or Replace

If the footings, posts and framing are genuinely sound, you may only need new decking and railing. That is a much smaller project, and we will tell you when it is the right one.

Replacement is the honest answer when the frame has rot, when the ledger was never flashed, when members are undersized for the span, or when the deck was built to a standard that would not pass today. Laying new boards over a frame like that hides the problem rather than fixing it.

Planned Around How You Use It

The useful questions are not about square footage. Where does the sun hit at the time of day you are actually out there? Does the grill need its own space away from the table? Do the stairs want to land toward the garage or toward the yard? Is there anyone in the house for whom a step down from the door is a problem?

That last one comes up more than people expect, and it is usually solvable at the design stage for very little — a landing at door height, a gentler stair rise, a rail that is comfortable to grip. Worth deciding before the footings go in rather than after.
