| Pressure-treated wood |
Usually the lowest starting cost |
Clean, inspect, and renew a suitable stain or water-repellent finish as needed.
|
Real grain and knots; treatment resists decay but does not stop water movement.
|
Can check, splinter, cup, and weather. Lower purchase cost comes with recurring
care. |
| Cedar |
Usually above standard treated lumber; grade matters |
Clean and inspect; renew the finish if retaining color and limiting weathering.
|
Natural grain; cedar heartwood has natural decay resistance. Unfinished wood
weathers gray. |
Soft wood can dent and scratch. Natural decay resistance is not immunity to rot.
|
| Uncapped composite |
Product-dependent; often relevant to an existing deck |
Follow the original product’s cleaning instructions; address stains and organic
buildup. |
Wood-plastic blend without a protective shell; exposed fibers can absorb
moisture. |
Older products may fade or stain more readily. Do not assume current
capped-product performance or warranty. |
| Capped composite |
Often above treated wood; entry and premium tiers |
Regular cleaning; no routine staining or sealing. |
Consistent colors and embossed grain; cap helps resist moisture and staining.
|
Not scratch-proof or stain-proof. Cap coverage, core, heat, and cleaning limits
vary. |
| PVC |
Often toward the higher end; overlaps premium composite |
Regular cleaning using approved products; no routine staining or sealing. |
Wood-free core resists moisture absorption; grain and finish vary by collection.
|
Can scratch and get hot. Temperature movement requires product-specific
installation details. |
