Many decks in Knoxville fail early because of poor framing, missing flashing, and moisture trapped against the house.
One of the first questions homeowners ask is:
👉 “How much does a deck cost in Knoxville?”
The honest answer is:
👉 It depends on how it’s built
I’ve seen decks that cost less upfront…
and end up costing more later because they were built wrong.
In Knoxville, price is not just about size —
it’s about structure, materials, and how the deck handles moisture.
Based on current material costs and our structural standards:
Small Decks (100–150 sq ft): $5,500 – $12,000+
Medium Decks (200–400 sq ft): $12,000 – $28,000+
Large or Custom Decks: $35,000+
Structural Wood Range: ~$18 – $32 per sq ft
Composite Systems (Trex/Azek): ~$45 – $110+ per sq ft
But these numbers don’t tell the full story.
