Completed by our Chicago crew
What We Did
A rooftop deck in Chicago takes punishment from every direction — UV off the open sky in summer, standing water when the drains slow, and wind that drives rain into every seam. This 650-square-foot pressure-treated pine surface had reached the point where refinishing wasn't optional. Six of the deck boards had deteriorated enough to warrant full replacement, and the existing finish had broken down to the point where bare wood was absorbing moisture rather than shedding it. The client arranged interior access for the crew, confirmed a water source and power outlet were available, and notified neighboring units — the kind of preparation that keeps a rooftop job moving without unnecessary stops.
We started with a thorough power wash to clear out embedded grime and any loose fiber before the wood had time to dry unevenly. The six failing boards came out and were replaced with treated pine matched to the surrounding deck, then the entire horizontal surface went through a full power sanding — consistent passes to open the grain and give the sealer something to grip. One coat of Rymar Xtreme Weather Sealer in a semi-transparent oil-based formula went down across all accessible floor surfaces, chosen by the client from the available color range. Furniture and planters were moved off before work began and returned to their spots once the deck was ready. The client also took advantage of the check payment discount, and an inspection option remains available within eighteen months of completion.

Frequently Asked Questions
Common questions from Chicago homeowners researching Structural Deck Repairs.
How much do structural deck repairs cost in Chicago, IL?
Pricing depends on the size of the deck, how many structural members need attention, and the extent of the damage — beams and posts cost more to address than surface-level issues. On this ~650 sq ft pressure-treated pine deck in Chicago, structural beam and post repairs came to $6,247. Decks with more widespread rot or those requiring additional material can run higher.
How long does it take to complete structural deck repairs?
A project of this scope — addressing beams and posts on a 650 sq ft deck — typically takes our crew two to three days depending on how many members need to be sistered, replaced, or re-anchored. We don't move on until the structure passes a load and fastener check, so timeline is driven by the work, not a schedule.
What's included in a structural deck repair service?
On this job we assessed and repaired the load-bearing beams and support posts, replaced deteriorated pressure-treated lumber where needed, re-secured connections, and verified the whole frame was plumb and stable before finishing up. We always inspect the ledger board, joist hangers, and post bases as part of the structural evaluation — nothing gets overlooked just because it wasn't the original call.
Can you replace joists and posts without rebuilding the whole deck?
In most cases, yes — targeted structural repairs can restore a deck to safe, code-compliant condition without a full tear-down, as long as the decking surface and ledger attachment are still sound. On this project, the beams and posts were addressed individually, preserving the existing pressure-treated pine decking and saving the homeowner the cost of a full rebuild.
