Outdoor Rooms Sized to Your Yard and Built for Missouri Weather
Composite decks recoup 78.8% of their cost at resale in our West North Central region and wood decks 73.5%, according to the 2025 Cost vs Value report. Campbells Carpentry LLC designs and builds custom decks in Warrenton, MO, Innsbrook, and Wright City: layouts sized to your yard, multi-level platforms, composite or pressure-treated or cedar boards, railings, built-in seating, stairs, landings, covered decks, and pergolas. Deck building starts with a conversation about how you will use the space.
We would rather talk you out of a feature you will not use than sell it to you. Owner-operated, we handle the design conversation, the estimate, and the build ourselves, so whoever sketched your layout is also setting posts. Estimates are free, recommendations are honest, and we do what we say we will do. After 5+ years of building decks that handle real Midwestern weather, we know what lasts.

Custom Decks Built Around Your Property
Custom Deck Design
Your yard sets the shape. We walk the lot with you, note the sun, the slope, the view worth keeping, and the doors you will use, then draw a layout that fits how you entertain, French-door walkout included if you want one.
Composite Decking
Capped composite boards carry 25-, 35-, or 50-year warranties from major makers and shrug off the freeze-thaw cycles that split wood. Color stays put, splinters never appear, and a hose replaces the annual stain. Expect them to outlast two or three wood decks.
Pressure-Treated and Cedar Decks
Treated pine costs the least and lasts 10 to 15 years with regular sealing; cedar resists rot naturally and runs 10 to 20 years. New treated lumber needs weeks to months to dry before it will take stain, and we tell you when.
Multi-Level Decks
Split a sloped yard into a dining platform and a lounge or hot-tub level below, joined by a run of stairs. Each tier gets its own guard where it sits more than 30 in. above grade, and the levels read as distinct rooms.
Deck Railings and Built-In Seating
Guards stand 36 in. high and reject a 4 in. sphere, and inside that rule you can choose cable, black aluminum balusters, or wood pickets to frame the view. Built-in benches along the edge double as seating and storage without crowding the floor.
Covered Decks and Pergolas
A roof turns the space into a three-season room; a pergola gives filtered shade with far less weight. Posts get sized for the 20 psf snow load the local code lists, and we tie the structure to the frame, never the boards.
Why Choose Us for Deck Building
Drawn From Your Yard, Not a Catalog
Catalog layouts ignore your slope, your sun, and the tree you refuse to cut. You get a plan drawn on your lot, with the grill downwind of the seating and the stairs landing where you walk, so the space feels like it belongs.
Honest Talk About Wood Versus Composite
Composite recoups 78.8% at resale and wood 73.5%, but resale is only part of the math. If you plan to move soon, treated pine is the smarter spend. If you plan to stay 25 years, composite pays off in weekends not spent staining.
Built for Real Midwestern Weather
July highs of 88°F and a winter design temperature of 6°F swing boards through plenty of movement yearly. We choose materials and fastening for that range, so your boards stay flat, your railings stay tight, and the surface handles ice and sun alike.
Stairs and Guards That Pass Code
Risers no taller than 7 3/4 in., treads at least 10 in., handrails between 34 and 38 in., and guards wherever the code requires them. You get it without asking, because a deck that fails inspection is not finished.
Views Kept Wide Open
Nobody builds a deck to stare at pickets. Cable rail, slim aluminum balusters, or a glass panel where the yard drops away keep the sightline clear from your chair to the tree line, and the guard still meets the code's spacing rule.
A Deck Sized to Its Purpose
Bigger is not better when half the boards never see a chair. We ask what you will do out there, then size the platform to a table for six, a grill, and a path between, so you pay for square footage you use.

Frequently Asked Questions
Should I build a wood or composite deck?
Composite wins on lifespan, 25 to 50 years against 10 to 15 for treated pine, and on upkeep. Wood wins on up-front outlay and on the look many want. Both recoup over 70% at resale, so choose by how long you will stay.
What is the downside of composite decking?
Heat. Dark composite boards in full August sun get hotter underfoot than cedar, and the initial spend runs higher than treated pine. Composite also flexes more between joists, which is why manufacturers tighten spacing, and scratches cannot be sanded out like wood.
Should a deck be built with 2x6 or 2x8?
Use 2x8 or deeper for joists; 2x6 covers only short distances before it bounces under the 40 psf live load in the code. Deeper joists also give stair stringers and railing posts more wood to bolt into, worth more than the lumber saved.
What are the ideal dimensions for a deck?
A 12x16 fits a table and grill; 16x20 adds room for a lounge corner. Campbells Carpentry LLC sizes each deck in Warrenton, MO, to the household using it, and a 16x16 with French doors is one we have built and would build again.
Is a multi-level deck worth it?
On a sloped yard, yes, or when you want dining and lounging to feel like different rooms. Extra tiers cost more in footings, guards, and stairs than one platform the same size, so the value comes from solving a grade problem, not novelty.
Can I add a second level to an existing deck?
Often, if the existing frame and footings can carry the added load, which we check first. A second tier gets its own posts and footings, ties into the original at one edge, and steps up or down by one or two riser heights.
Can I build a roof over my deck?
Yes, with posts and footings sized for the roof's weight and the 20 psf snow load, not just the deck's. Campbells Carpentry LLC has spent 5+ years building covered decks around Warrenton, MO, and a roof is easiest to plan in early.
Can I mix wood and composite in the same deck?
Absolutely, and mixing is a common way to manage spend: composite boards and cap rail where feet and hands touch, treated lumber for the frame underneath. Seal the wood and the two age evenly. Most composite brands sell rail systems for exactly this.
