Flat lots are rare in Sevier County, so building a deck here usually means building up — an elevated deck on a slope. Done right, that's a huge advantage: a steep lot is often where the best ridgeline and valley views are. But an elevated deck has to be engineered and built for the height and terrain. Here's what matters.
Everything starts underground. Elevated decks carry real loads at height, so footings must be dug below frost depth into stable ground and sized for the structure above. On our mountain soil, which moves with freeze and thaw, proper footings are what keep the whole deck solid for the long haul.
The taller the deck, the more the structure matters. Correctly sized posts and beams carry the load, and lateral bracing keeps a tall deck from swaying. Poorly built elevated decks that skip the bracing are the ones that feel bouncy or, worse, fail. We build them to feel rock-solid even high off the ground.
A slope is an opportunity. A multi-level deck can step down the grade in tiers, creating separate zones for dining, lounging, and a hot tub while working with the terrain instead of fighting it. It turns a challenging lot into a dramatic, functional outdoor space.
On an elevated deck, railings are safety-critical — and they shouldn't wall off the view you built up to see. Cable and glass railings keep the scenery open while meeting code. Getting the railing right is part of getting the whole deck right.
Elevated decks should always be permitted and inspected — it's a safety check, not just paperwork. We handle the permitting and build to code so your deck is safe, insurable, and ready to enjoy. Ask us about building on your mountain lot.
