How much does a new deck cost in Lebanon?
It depends mostly on size, material, and height off the ground, but here's the typical shape of it: a basic pressure-treated deck often lands somewhere in the neighborhood of $25 to $45 per square foot installed, while composite decking typically runs higher, often in the $45 to $75 per square foot range once you count decking, footings, framing, and railing. A small 10x12 wood deck might land at the low end of that; a large multi-level composite deck with built-in features climbs toward the high end fast. Real pricing depends on your yard, your ground, and what you're picturing, which is why we quote after hearing the details instead of guessing over the phone.
Composite decking or treated pine — which is better?
Neither is objectively "better" — they trade off differently. Pressure-treated pine costs less upfront and is the material most existing decks around Lebanon are built from, but it needs regular staining or sealing to keep from graying, cracking, and splintering in this area's humid summers. Composite decking costs more to install but doesn't need staining, resists moisture and rot better, and holds its color longer. If you want the lowest starting price and don't mind maintenance, wood is a solid, proven choice. If you'd rather pay more once and mostly leave it alone, composite typically pays that difference back in time saved. Our composite decking page goes deeper on the tradeoffs.
Do I need a permit to build a deck?
Usually, yes, for anything beyond a small ground-level platform, but the exact rule depends on where the property sits — inside Lebanon city limits or out in unincorporated Laclede County — and how big and how tall the deck is. Attached decks, anything requiring footings, and taller structures are the ones most likely to need a permit and an inspection. The safest move is to check with the City of Lebanon or the Laclede County building department before work starts, since requirements can change and a deck built without a required permit can turn into a real headache later, especially at resale.
How long does it take to build a deck?
A straightforward single-level deck typically takes anywhere from a few days to about two weeks of actual build time, depending on size and complexity. Multi-level decks, covered decks and porches, or builds with a lot of custom framing for a sloped lot take longer. Weather plays a role too — a string of rainy days in the middle of a build will push the finish date back. We give a realistic timeline once we know the scope, not a generic number that ignores your yard.
How deep do deck footings need to be?
Deep enough to sit below the local frost line, which is what keeps a footing from heaving as the ground freezes and thaws through a Missouri winter. The exact required depth depends on local code and soil conditions, and it's set by whoever has jurisdiction over the permit — the City of Lebanon or Laclede County. This isn't a place to guess or cut corners: a footing poured too shallow is one of the more common reasons an older deck starts to lean, sag, or pull away from the house years later.
What railing options do I have?
Quite a few. Standard wood railing painted or stained to match the deck is the most common and least expensive option. Composite and metal-baluster railings cost more but need little to no maintenance and hold up well against sun and moisture. Cable railing has become a popular choice for homeowners who want an open view — useful if your yard backs up to trees or a good sunset. Code sets minimum height and baluster spacing requirements for safety, so railing choice mostly comes down to material and look rather than whether a raised deck needs one at all.
How often does a wood deck need to be stained or sealed?
Typically every two to three years, though it depends on the wood, the sun exposure, and how the previous coat was holding up. A deck that faces full afternoon sun or takes a beating from Ozark humidity often needs attention closer to the two-year mark; a shaded deck might stretch longer. Signs it's due: water stops beading on the surface and soaks in instead, the wood starts to gray, or small surface cracks start showing. Staying ahead of the schedule is a lot cheaper than letting a deck gray out and crack, then needing to sand and repair before it can be resealed.
Should I build a deck or a patio?
Both have a place, and the right call depends on your yard and what you want out of the space. A deck makes sense when the ground slopes, when you want to be elevated off the yard, or when you're building off a walkout basement or a second-story door. A patio makes more sense on flat ground where you don't need the height and want to avoid the maintenance that comes with wood. Decks generally give you more design flexibility for multi-level layouts and built-in features; patios generally cost less per square foot and need less upkeep over time.
Can my old deck be repaired, or does it need to be replaced?
It depends on what's actually wrong with it. Surface issues — graying wood, a few soft boards, loose railing — are usually repairable. Structural issues are a different story: a ledger board that's pulling away from the house, footings that have shifted or heaved, or broad rot in the framing underneath the decking usually mean the safe answer is replacement, not a patch. A lot of decks around Lebanon are original to 1990s and 2000s-built homes, which puts them well past the point where a quick fix is the honest recommendation. We'll tell you straight which category yours falls into.
Can you build a deck on a sloped or wooded lot?
Yes — it's common around here. Laclede County has plenty of hilly, wooded terrain, and a sloped lot usually just means the deck needs taller support posts, footings set for the grade change, and sometimes stairs down to the yard instead of a single-level platform. Trees close to the build site add planning considerations too, from root systems near footing locations to branches overhead. None of that rules out a deck — it just means the design has to account for the lot instead of assuming flat ground.
What's the difference between a deck and a covered porch?
A basic deck is open to the sky; a covered deck or porch adds a roof structure, which changes both how you use it and what goes into building it. A cover means shade and rain protection, which extends how many days a year the space actually gets used, but it also means additional framing, roofing material, and often a look at how the structure ties into your existing roofline. Screened-in options add bug protection on top of that. Our covered decks & porches page walks through the options in more detail.
When's the best time of year to build a deck in Missouri?
Spring and fall tend to be the easiest building windows — mild temperatures and typically less brutal humidity than mid-summer. That said, deck construction happens across most of the year here; summer builds are common too, just hotter to work in, and winter builds are possible between weather windows as long as footings can be poured before hard freezes set in. If you're aiming to have a deck ready for lake season or summer cookouts, planning and starting in late winter or early spring gives the most buffer.
