In Spokane, composite decking costs $4 to $8 more per square foot installed than wood but avoids the staining and sealing costs that wood requires every two to three years. Composite handles Spokane's freeze-thaw cycles better and lasts longer without rot or splitting. Wood costs less upfront and is the better choice for homeowners on a tighter budget or planning to sell within a few years.
Pressure-treated wood decking runs $8 to $14 per square foot installed. Composite (Trex, TimberTech) runs $12 to $22 per square foot installed. On a 400 square foot deck, that gap is roughly $1,600 to $3,200 more for composite at the surface level. Cedar falls in the middle at $10 to $18 per square foot. If budget is the primary concern and the homeowner is comfortable sealing every couple of years, wood is the reasonable choice.
Pressure-treated wood and cedar decks in Spokane need staining or sealing every two to three years to prevent moisture damage. A professional re-seal on a 400 square foot deck runs $300 to $700 each time. Over 10 years, that adds $1,000 to $2,800 in maintenance cost that composite does not require. At the 10-year mark, the total cost of ownership for wood and composite is often within $500 to $1,000 of each other.
Spokane's freeze-thaw cycle is the key performance factor to consider. Wood absorbs moisture and expands and contracts with each freeze-thaw event, which causes cracking, splitting, and cupping over time. Composite boards are far less responsive to moisture and temperature changes. For decks on north-facing lots in Mead or Five Mile Prairie that stay wet longer into spring, composite holds up noticeably better than wood over a 15-year period.
Wood deck maintenance: seal or stain every 2-3 years, sand rough spots annually, replace cracked boards as needed. Annual upkeep time: 4-8 hours. Composite deck maintenance: rinse with a garden hose, occasional scrub with soap and water. Annual upkeep time: 1-2 hours. For homeowners who want a deck that requires minimal seasonal attention, composite is the practical choice in Spokane's climate.
Composite typically lasts 25 to 30 years with minimal maintenance. Pressure-treated wood lasts 15 to 20 years with regular sealing. Cedar can match composite in lifespan if maintained well but requires more consistent upkeep to get there.
Modern composite boards have improved significantly in appearance. Higher-end TimberTech and Trex lines have a convincing wood grain texture and natural color variation. Lower-end composites can look more uniform. At the estimate visit, we can show you samples of both so you can judge in person.
Both add value, but composite may be more attractive to buyers because it signals lower maintenance. A properly maintained wood deck is just as valuable at resale; the concern is whether the buyers will factor in the upcoming seal cycle.
Yes, and that is what we do on every composite deck. The frame is always pressure-treated lumber. Composite boards are the surface only. The frame needs to meet specific joist spacing requirements for composite, which we build to in the permit drawings.
We built this operation around one idea: a deck is a structural investment, not a cosmetic one, and it deserves the same care you would put into any other part of your home. We work across Spokane, South Hill, Five Mile Prairie, Mead, and the Spokane Valley. Every build gets a permit, pressure-treated or composite framing rated for the Pacific Northwest, and a final inspection before we call the job done. We give you a flat written estimate after the site visit and we stand behind the work with a workmanship warranty.
