What we handle on a deck build

Decks look simple. Most are not. The framing has to carry live and dead loads (40 + 10 psf for residential), survive 30+ Kansas City winter freeze cycles, and stay attached to your house through wind events. The single biggest cause of deck failure is improper attachment to the structure or undersized / shallow footings. Both are invisible from above. Both are easy to skip. We don't.

Our scope on a typical deck project includes:

  • Layout & permit — site walk, layout staked, lot-line and easement check, structural and railing layout per code, permit submittal and review.
  • Footings — concrete piers dug to KC frost depth (36" minimum, 42" in some municipalities), proper diameter for the load (engineered for larger or two-story decks), Sonotube or formed, with rebar where code requires, post-base hardware (Simpson ABA or equivalent) embedded in fresh concrete.
  • Ledger attachment — siding pulled back at attachment line, ice-and-water shield installed, ledger lag- or through-bolted per the IRC ledger-attachment table, two-piece flashing (drip cap + waterproof membrane), siding reinstalled. The ledger is structural; the flashing is what keeps your rim joist alive.
  • Framing — pressure-treated framing for any below-deck-board structural members, joists at 12" or 16" o.c. depending on decking choice (composite often requires 12"), proper joist hangers (Simpson LUS or equivalent — not toe-nailed), engineered beams sized to the deck span, beam-to-post connections with bolted hardware (not shoved in a notch).
  • Decking install — pressure-treated, cedar, or composite. Hidden fasteners on composite where compatible. Proper end-of-board and butt-joint detailing. Picture-framing on premium decks. Breaker boards for long runs.
  • Rails & balusters — 36" or 42" minimum height per municipality, 4" max baluster spacing, rail anchored to structural posts (not just to fascia), continuous top rail. Cable rails, glass rails, aluminum rails, or wood per your selection.
  • Stairs — stringer cut to consistent 7-3/4" max riser / 10" min tread, anchored to deck and to a footing or pad at grade, 34-38" graspable handrail on at least one side, code-compliant guards on any open side.
  • Skirt & finish details — lattice, framed skirt panels, or open-skirt per your preference. Fascia boards on the rim. Trim around posts where applicable.
  • Lighting / electrical (optional) — low-voltage post lights, riser lights, or deck-floor accents wired to a transformer. Outlets and switches installed by a licensed electrician.
  • Cleanup & final inspection — site cleanup, debris hauled, final permit inspection scheduled and walked.

What to expect — timeline and draws

Most KC deck builds run 1.5 to 4 weeks of on-site construction once materials are delivered, plus 1 to 3 weeks of permit lag on the front end. Composite decks add 1 to 2 weeks of material lead time on premium boards. Multi-level decks, decks with roofs or screen rooms, and decks with structural-engineering requirements run 4 to 8 weeks.

Before any digging happens, you receive a written schedule with the major milestones and inspection points. Draws against the contract are tied to milestones rather than the calendar. A standard structure looks like:

  • 30% at signing — secures the schedule slot, orders material (especially composite, which is order-specific).
  • 40% at framing-complete milestone — footings poured and inspected, framing up and inspected, ledger flashed and bolted, decking partially or fully installed.
  • 20% at substantial completion — rails, stairs, finish detail, lighting all done.
  • 10% retained until the punch list is fully signed off and the city final inspection has passed.

Pricing factors

Kansas City decks generally fall into these bands by material on a single-level 12x16 (192 sq ft) deck with code rails and one set of stairs:

  • Pressure-treated — $7,000 to $14,000. Cheapest material, requires annual maintenance to look good past year 3.
  • Cedar — $11,000 to $20,000. Beautiful new, silvers without stain, 15-25 year life.
  • Mid-grade composite (Trex Enhance, TimberTech AZEK Harvest) — $14,000 to $28,000. Maintenance-free, 25-year limited warranty typical.
  • Premium composite / PVC (Trex Transcend, TimberTech AZEK Vintage) — $20,000 to $40,000+. Closest-to-real-wood look, 50-year limited warranty typical, full color and grain options.

Where your project lands inside those bands depends on:

  • Footprint — bigger decks scale roughly linearly per sq ft on the same material.
  • Stairs — each set of stairs adds $1,000 to $4,000 depending on rise, tread material, and rail style.
  • Levels — multi-level decks add framing, rail, and one or more stair runs — typically 30-50% premium per added level on the same material.
  • Rails — standard pressure-treated baluster rail is cheapest. Cable rail $50-$100/lf premium. Glass rail $80-$150/lf premium. Aluminum picket rail $30-$60/lf premium.
  • Roof / screen room — covered structures add structural loads, footing requirements, and another layer of permit. Often $15,000 to $40,000+ on top of the deck.
  • Demolition of existing deck — tear-out and disposal: $1,000 to $4,000 depending on size and access.
  • Site access — backyards with no machine access (over a fence, no gate, narrow side yards) drive labor cost up significantly.

Why customers pick Tessera for decks

  • You hear back fast. Quote within 24 hours, not three weeks.
  • Footings are dug to actual KC frost depth, not "looks deep enough."
  • Ledgers are flashed correctly. Your rim joist stays dry.
  • Rails and stairs are code-spec, not handyman-spec.
  • The estimate is line-itemed enough to actually decide on, including material grade and stair count.
  • The schedule is written down. If we slip, you hear about it the same day.
  • You retain 10% until the punch list and final inspection close out.

Deck FAQ

What homeowners ask us most.

How long does a deck build take in Kansas City?

A standard 12x16 to 14x20 deck (single-level, no roof) runs 1.5 to 3 weeks of construction once material is on site, plus 1 to 3 weeks of permit lag depending on your municipality. Multi-level decks, decks with roofs or screen rooms, and decks integrated with structural changes run 4 to 8 weeks. We give you the full schedule, including permit lag, in writing before signing.

Do I need a permit for a deck?

In KC-metro municipalities, almost always yes — any deck attached to the house typically requires a permit, and most jurisdictions also require permits for freestanding decks above a certain height (often 30") or footprint. The permit drives the inspection of footings, framing, and rails — which protects you on resale and on insurance claims. We pull the permit and walk every required inspection. Skipping the permit on a deck is one of the most common things that comes back to bite homeowners at sale time.

What does a deck cost in KC?

A standard 12x16 (192 sq ft) pressure-treated deck with code-compliant rails and a single set of stairs runs $7,000 to $14,000. The same deck in cedar runs $11,000 to $20,000. The same deck in mid-grade composite (Trex Enhance, TimberTech AZEK Harvest) runs $14,000 to $28,000 — composite labor is similar to wood; the material premium is the difference. Premium composite (Trex Transcend, TimberTech AZEK Vintage) and full PVC decking run $20,000 to $40,000+ on the same footprint. Larger or multi-level decks scale roughly linearly per square foot, with stairs and framing changes adding mid-thousands each.

Pressure-treated vs cedar vs composite — what should I pick?

Pressure-treated lumber is the cheapest and lasts 10-20 years if maintained, but it warps, checks, and needs annual cleaning and resealing to look good past year three. Cedar looks beautiful but ages to silver-gray quickly without maintenance and lasts 15-25 years. Composite (Trex, TimberTech, Fiberon) costs 2-3x pressure-treated installed but eliminates the maintenance cycle — no sealing, no staining, no warping, no splinters. PVC is similar to high-end composite. Honest take: if you plan to be in the home 8+ years and you do not want to spend Saturdays maintaining a deck, mid-grade composite pays for itself in time saved. If you are flipping or planning to move within 5 years, pressure-treated is the right answer. We can model both for you in the estimate.

How deep do the footings have to be?

KC sits in a frost-depth zone that requires footings 36" below grade for any structural deck attached to a house. Local code in some KC-metro municipalities pushes that to 42". We dig to the inspector's requirement and pour to it — this is the single most common shortcut taken by handymen and storm-chaser deck builders, and it directly causes deck failures within 5-10 years from frost heave. We do not save money here.

How do you attach the deck to the house?

Through a properly flashed ledger board, lag-bolted (or through-bolted) into the house's rim joist per the IRC ledger-attachment table. The flashing is the part most people get wrong: a two-piece flashing system (drip cap + ice-and-water shield wrapping over the ledger) protects the rim joist from rot. We pull house siding back, install ice-and-water shield, install the ledger with code-spec fasteners, install drip cap, and reinstall siding. A rotted rim joist behind a wood ledger is one of the most expensive deck mistakes you can find — sometimes leading to interior wall damage that doubles the project cost. Good flashing is non-negotiable.

What about rails, stairs, and code?

Guardrails on any deck more than 30" above grade must be 36" minimum (KC residential code per 2018 IRC; some municipalities adopt 42" — we check). Balusters spaced so a 4" sphere cannot pass through. Stairs need 34-38" graspable handrails on at least one side, treads 10" minimum, risers consistent at 7-3/4" maximum, and proper open-riser limits where required. We follow the code, not the cheaper version with 33" rails and skipped handrails — those fail at inspection and (more importantly) hurt people.
