Siding Built for the Wet Side of Oregon
Old T1-11 and hardboard siding around St Helens is hitting the end of its life — soft corners, swollen edges, paint that won’t hold. We replace it with materials made for this climate:
- Fiber-cement siding (James Hardie) — rot-proof, fire-resistant, holds paint for years
- Engineered wood (LP SmartSide) — warm wood look, engineered against moisture
- Dry-rot repair done right — we fix sheathing and framing before new siding goes on, not over it
- House wrap, flashing & rainscreen details that keep water out of the wall for good
- Trim, soffit & fascia replacement to finish the envelope
Repaints Where the Prep Is the Job
Anyone can spray paint on a wall. What makes an exterior repaint last 10 years in Columbia County is everything that happens first:
- Pressure wash and full dry-out before any paint moves
- Scrape, sand & spot-prime every failing area — no painting over peel
- Caulk every gap at trim, windows, and joints to lock moisture out
- Repair rot and damaged trim before it’s hidden under fresh color
- Premium PNW-rated paints applied at proper thickness, in the right weather window
One recent example: a full exterior refresh in Scappoose — washed, prepped, repaired, and repainted into a home the owners are proud to pull up to.
Common Questions
How much does it cost to paint a house exterior in the St Helens area?
Most full repaints on single-family homes run roughly $5,000–$12,000 depending on size, height, siding condition, and how much prep and repair is needed. Real prep is most of the job — and most of the price. Estimates are free.
What siding holds up best in Oregon’s climate?
Fiber-cement (James Hardie) and engineered wood (LP SmartSide). Both resist rot, handle constant moisture, and hold paint far longer than old T1-11 or hardboard. We’ll walk you through the cost and look differences on site.
Can you fix dry rot you find under the siding?
Yes — and in this climate we usually find some. As a general contractor, we repair sheathing, framing, and trim properly before new siding goes on, instead of covering it up.
How often should a house be repainted in the Pacific Northwest?
Every 7–10 years for most homes — sooner on south- and west-facing walls. Peeling, chalking, and caulk gaps mean it’s time. Waiting too long lets moisture in and turns a paint job into a repair job.
When is painting season in Oregon?
Late spring through early fall, when surfaces are dry and temps stay above the paint’s minimum. Booking your estimate in winter or early spring puts you at the front of the schedule.
