Outdoor Spaces You Can Use More Than Three Months a Year
A deck in Columbia County has one job beyond looking good: surviving nine months of rain without rotting, sagging, or turning into a slip hazard. That comes down to things you can’t see in the photos — footings sized for our soil, proper ledger flashing so the house never rots behind the deck, joist protection, and fasteners that don’t streak and corrode.
We build:
- New custom decks in cedar and composite (Trex-style PVC-capped boards)
- Covered decks & patio covers — timber-framed roofs so the BBQ works in November
- Deck replacements — new structure on a footprint you already love
- Railings & stairs — wood, metal baluster, and cable rail
- Deck repair & refastening — soft spots, wobbly rails, failing stairs

Deck Building Questions, Answered
How much does a new deck cost in the St Helens area?
As a rough guide: cedar decks often run $40–$60 per square foot built; composite $60–$90 per square foot — driven by height, railing style, stairs, and site conditions. Covers add the roof structure. Firm written bid after a free site visit.
Cedar or composite — which is better for Oregon?
Cedar is cheaper up front and beautiful, but wants cleaning and re-staining every couple of years. Composite costs more once and then shrugs off Columbia County moss and moisture with almost no upkeep. We build both and will quote both ways if you’re deciding.
Do I need a permit to build a deck in Columbia County?
Decks over 30″ above grade, attached to the house, or covered generally need a permit, and requirements differ between St Helens, Scappoose, and the county. We handle permitting as part of the project.
Can you cover my existing deck?
Usually — if the structure and footings can carry the load, we add a timber-framed cover so the deck works through the rainy season. If it can’t support one, we’ll tell you exactly what it would take.
How long does a deck build take?
Most builds take 1–2 weeks on site. Permit review time varies by jurisdiction and is the main driver of the overall timeline.
