Build Portland Decks That Defy Constant Rain
Portland decks rot predictably: standing water on flat surfaces, moisture trapped under railings, insufficient ventilation beneath boards, and untreated wood exposed to rain. Most decks last barely ten years before requiring major repairs or complete replacement.
Our waterproofing specialists protect the property structures from Portland’s nine months of rain, plus summer extreme sun exposure. We ensure moisture barriers, proper flashing, and sealing are applied to vulnerable areas, and we address drainage concerns to prevent water damage and structural deterioration.
Decking material selection balances budget and performance: pressure-treated lumber offers economy, composite resists rot and fading, or hardwoods provide premium aesthetics. Installation details determine longevity, proper fastener spacing, adequate gaps for expansion, and edge sealing where water enters end grain. Railings get built to code height with secure attachments.
Regular maintenance extends life further, and we offer programs handling cleaning and resealing.
