Frequently Asked Questions

Do I need a permit for a deck in Idaho?

Yes. Most Idaho cities require a building permit for decks over 200 sq ft or more than 30 inches above grade. Your contractor handles all permit applications and inspections.

What’s the best decking material for Idaho weather?

Composite decking (like Trex or TimberTech) is the most durable for Idaho’s freeze-thaw cycles — no rotting, warping, or annual staining. Cedar is the premium natural option. Pressure-treated pine is the budget-friendly choice but requires annual sealing.

How much does a deck cost in Eastern Idaho?

Expect $25–$70 per square foot depending on material and complexity. A typical 300 sq ft pressure-treated deck runs $7,500–$12,000. Composite decks run $13,500–$21,000 for the same size. Our near-wholesale pricing can save you 20–35%.

How deep should deck footings be in Idaho?

Idaho’s frost line is 30–36 inches in Eastern Idaho. Deck footings must extend below the frost line — typically 36–42 inches deep with concrete piers. This prevents frost heave, which is the #1 cause of deck problems in our area.
