How deck replacement actually goes together

Every deck replacement job is built in a specific order, and the layers you never see once the job is finished are what actually keep water out of the wall or roof. The diagram walks through it step by step.

How a Deck Structure Is Built

  1. Footing — poured below Maine’s frost line so winter heaving cannot move it
  2. Post — carries the beam load down to the footing
  3. Beam — spans between posts and carries the outer ends of the joists
  4. Ledger — bolted to the house framing, with flashing that diverts water away from the wall
  5. Joists — span from the ledger to the beam, sized and spaced to the decking and the load
  6. Decking — the walking surface, fastened on top with spacing for drainage

About deck replacement

When an old deck is soft, wobbly or pulling away from the house, a full replacement is treated as a new build: the old deck comes off, the footings and framing are built new, and the new surface, railings and stairs go on. That is the only way to deal with hidden rot at the ledger and frost-heaved footings, and it is how Cardinal Exteriors approaches it. It lets you change the size, shape and material at the same time.

This page is part of our deck building work, which lists typical price ranges and materials. Other related services: new deck building, composite and PVC decks, siding replacement, roof replacement.

What the job involves

  • The existing deck is removed and disposed of, and the house wall behind the ledger is inspected.
  • Rotted rim or sheathing behind the old ledger is repaired and the wall is flashed.
  • New footings go below frost; new posts, beams and joists are framed.
  • New decking, railings, stairs and landings are installed in the material you choose.
  • Permits are pulled where required and the site is cleaned up.

Signs it is time

  • Soft or spongy boards and joists
  • A ledger pulling away from the house or rust-streaked fasteners
  • Posts that have heaved, leaned or rotted at the base
  • Railings that wobble or are lower than today's code expects

What affects the price

  • Removal and disposal of the old deck
  • Repairs to the house wall behind the ledger
  • New size, height and shape
  • Decking and railing materials
  • Footing type and site access

Every job is priced from a free on-site estimate, with a fixed-price written proposal before work starts.

Deck Replacement: When to Rebuild vs. Re-Deck

Not every worn-out deck needs to come down to the footings. Some just need new boards and railing over a frame that's still sound; others have problems in the structure itself that no amount of new decking will fix. Telling the difference is the first thing we do on any deck replacement estimate.

Signs the Substructure Needs Replacing, Not Just the Boards

  • Joists or beams that feel soft, spongy, or spring noticeably underfoot when you walk the deck.
  • Rusted, undersized, or missing joist hangers — common on older decks built before hangers were standard practice.
  • A ledger board with no visible flashing, or soft/discolored wood where the ledger meets the house.
  • Posts sitting on buried wood, stacked pavers, or shallow footings rather than a proper footing below the frost line — common on decks built decades ago under an older code.

Re-Decking Over a Sound Frame

When the framing checks out — solid joists and beams, properly sized hardware, footings below the frost line — re-decking (removing just the decking boards and railing and building back on the existing frame) is faster and less expensive than a full rebuild. Even on a re-deck job, we open up and check the ledger connection, since older decks frequently have little or no flashing there even when the rest of the frame is fine.

Bringing an Older Deck Up to Current Code

A deck built decades ago was built to the code in force at the time, and guardrail height, baluster spacing, and stair requirements have all changed since. Once a permitted replacement or major repair starts, the guardrail and stair details typically need to meet current code even if the rest of the frame is being reused — worth planning for if your deck's railing or stairs look original.

    We hired Cardinal Exteriors to reside our house and install all new windows, and it was a terrific experience from start to finish! Bob was one of the very best contractors we've ever worked with (and we've worked with many over the years). He was extremely responsive, helpful, respectful of wishes and concerns, and never pressured us in any way.

    CARDINAL EXTERIORS re-shingled my roof. Bob Proved to be Knowledgeable and Trustworthy. He was responsive to my questions and took the time to explain the materials being used and the steps they were taking to weatherproof the roof of my home. The work crew was polite and they cleaned up the job site at the end of each work day.

    Bob @ Cardinal Exteriors replace 26 windows and resided our office building in Westbrook in 2025. Being in the construction business, we understand how proposals sometimes come with change orders and surprises if not outlined up front. Bob and his team finished our job on schedule and actually below budget.
