Decks that earn their space

A deck turns the space between your back door and your yard into somewhere you actually use. But it has to earn it — framing that handles the load, footings that reach stable soil, materials that survive the seasons. Ryan builds decks himself, footings to final screw. No crew, no subcontractors.

Deck types we build

Ground-level decks

Close to grade — the simplest, most affordable option for flatter yards. Pressure-treated framing, built to the same structural standard as an elevated deck.

Elevated decks

For raised foundations and hillside lots, common in Altadena. Deeper footings, engineered posts and beams, flashed ledgers, and Simpson hardware at every connection — built to pass LA County inspection.

Hillside decks

Altadena’s toughest builds: cantilevered or tall-post decks anchored to deep footings, engineered for slope and Southern California seismic loads.

Multi-level decks

Stepped levels for terrain a single flat deck won’t fit — distinct dining and lounging zones, stairs built to code.

Materials

  • Pressure-treated pine — most affordable; 15–20 years with maintenance, takes stain or paint well
  • Cedar & redwood — natural beauty and rot resistance; quality-grade lumber, not big-box warp
  • Composite (Trex, TimberTech, Fiberon) — no splinters, rot, or staining; hidden fasteners and 25-year warranties

What makes a deck last

The details most contractors rush: footings to code depth on concrete piers, a properly flashed ledger (the #1 cause of deck collapses nationwide), correctly sized framing with rated Simpson hardware, and airflow under the boards so framing dries out.

Building on Altadena terrain

Altadena isn’t flat. Builds here mean slope analysis, soil evaluation, hillside access logistics, and positioning the deck to capture mountain or city views. Ryan has built on the flats and the steep hillsides across the San Gabriel Valley.

Permits and inspections

Most LA County decks require a permit. Ryan handles submission, revisions, and inspections — the deck passes because it’s built to code from the start, not lucky at inspection.

Pricing guidance

Deck construction in Altadena typically costs $30–$60 per square foot for pressure-treated wood and $45–$85 for composite. A standard 200-square-foot deck runs $6,000–$17,000 depending on material, height, and complexity. Elevated hillside decks cost more due to structural requirements.

Common questions

How much does a deck cost in Altadena?
Pressure-treated wood decks run $30–$60 per square foot. Composite decks cost $45–$85. A standard 200-square-foot deck ranges from $6,000 to $17,000. Elevated or hillside decks cost more due to additional structural framing. Ryan provides a detailed estimate after evaluating your property.
Wood or composite — which is better?
Both have merits. Wood (cedar, redwood, pressure-treated) costs less upfront and has a natural look but requires regular staining and sealing. Composite costs more initially but needs minimal maintenance and won't splinter, rot, or fade. Ryan explains the tradeoffs for your specific situation.
Do I need a permit for a deck in Altadena?
Most decks require a building permit in LA County, especially those elevated more than 30 inches above grade. Ryan handles the permit process, including plan submission and inspections, so you don't have to coordinate with the building department.
How long does deck construction take?
A ground-level deck takes 1–2 weeks. Elevated decks with complex framing take 2–4 weeks. Permit timeline adds to the schedule but Ryan handles that process. He gives you a realistic total timeline upfront.
Can you build a deck on a hillside?
Yes. Hillside decks are one of Ryan's specialties. These require deeper footings, engineered structural plans, and more robust framing — but they create usable outdoor space on properties where flat ground doesn't exist. Ryan has built numerous hillside decks in Altadena and the surrounding foothills.
