At Deck Builders of Maryville we build decks for homeowners across Blount County, and we build them one at a time, designed around the house they attach to. Some clients want a straightforward pressure-treated platform off the back sliders. Others want a multi-level composite deck with a picture-frame border, custom railing and a pergola for shade. Both get the same attention to the parts nobody sees: footing depth, ledger attachment and flashing, joist spacing, and stairs that meet code.
Maryville is the seat of Blount County, sitting at roughly 900 feet where the Tennessee Valley starts climbing toward the Great Smoky Mountains. That position shapes everything we build. Head south-east along US-321 — Lamar Alexander Parkway — toward Townsend and the ground rises steadily to the national park boundary; the lots get steeper, and decks stop being platforms and become structures with tall posts, deeper footings and long stair runs. Out along the US-129 Alcoa Highway corridor and around McGhee Tyson, the valley floor is comparatively level, which means lower decks and shorter stairs. Two projects the same size on those two lots are not the same job, and they should not carry the same price.
The weather is the other constant. East Tennessee takes well above the national average in annual rainfall, our summers are humid, and at this elevation winter delivers genuine freeze-thaw cycling rather than one hard freeze. That combination is what actually kills decks here — water sitting in board checks and freezing, footings lifted by frost, humid air trapped under a sealed low deck, mildew on any surface that never fully dries under mature canopy. Every one of those has a design answer: footings carried below frost depth, joist tape, real perimeter ventilation, correct board spacing, and flashing done properly the first time.
It is also why the material conversation matters more here than in a drier climate. Wood decking is the most affordable way to get the space you want, and a well-built pressure-treated deck lasts a long time — but here it comes with a maintenance schedule attached, and that schedule is shorter than most people expect. Composite decking costs more up front and gives most of that time back, resisting moisture, mold, insects and UV fading without annual refinishing. Neither is automatically right; it depends on your budget, how long you plan to stay, and how you feel about spending a weekend re-staining.
Permitting is worth knowing about before you start, because Blount County is not one jurisdiction. Addresses inside Maryville city limits permit through the City of Maryville. Alcoa — laid out in the late 1910s as a planned town for the aluminum works and still its own municipality — runs its own building and codes department. Everything outside those city limits goes through the county. Neighbouring streets can answer to different offices, and filing with the wrong one surfaces at inspection, which is an expensive time to find out. We confirm the jurisdiction for your address before quoting and handle the permit either way.
Every project starts with a free on-site estimate. Someone comes out, looks at the actual grade and access, discusses what you have in mind, and follows up with a written price. No obligation and no pressure to decide on the spot — and if what you want lands above budget, we will show you what adjusting size, material or railing would do to the number.
