Deck Planning

Deck Framing Matters More Than Most Homeowners Think

The part homeowners never see is the part that decides how long the deck lasts.

The part homeowners do not see

Once the surface boards go down, the framing disappears. The frame is doing all the work — carrying weight, resisting movement, and keeping water where it belongs.

Joists and beams

Joist spacing matters. Composite manufacturers often specify tighter spacing than wood does. Beam size and post placement decide whether the deck feels rigid underfoot.

Posts and footings

Footings must go below the frost line. In Massachusetts that's typically around four feet. Undersized footings are one of the most common shortcuts we see.

Ledger attachment

The ledger connection is the single most safety-critical detail on an attached deck. It must be bolted correctly and flashed correctly. Nailing a ledger is not acceptable practice.

Flashing and water management

Water is patient. Good flashing keeps it out of the house wall and off the joists. Bad flashing is where slow-motion failure begins.

Why resurfacing requires inspection

Putting new composite over a compromised frame gets you a beautiful deck that fails from below. We always inspect first.

How poor framing shortens deck life

The surface might last 25 years. The frame decides whether it gets that chance.

Square Cut's structure-first approach

We plan and build the frame like it's the whole project — because in terms of longevity, it basically is.

Frequently asked questions

Can you see framing problems without opening the deck?

Sometimes, from below. But a real inspection often means pulling a board or two to look at joists and fasteners.
