Plumbing service in Oregon
Call NowOregon plumbing is mostly wet-climate plumbing: steady winter rain, crawl spaces, older Portland homes and rural wells, with colder, drier conditions east of the Cascades.
Oregon weather and your plumbing
Western Oregon has mild, very wet winters and dry summers, with occasional ice storms and snow in Portland and the Willamette Valley. East of the Cascades, Bend and the high desert are colder and drier with hard freezes.
Season by season in Oregon
- Rainy season
- Months of steady rain saturate soil, flood crawl spaces and test sump pumps and sewer laterals.
- Ice and snow events
- Occasional Portland ice storms catch pipes in crawl spaces and exterior walls unprepared.
Problems the Oregon climate causes
Wet crawl spaces
Cause: Long rainy season.
Result: Standing water in crawl spaces corrodes pipes and damages insulation.
Do: Check crawl spaces after heavy rain and consider a crawl-space sump.
Frozen pipes in rare freezes
Cause: Ice storms west of the Cascades.
Result: Pipes not built for cold split.
Do: Insulate exposed pipes and disconnect hoses before winter.
Housing in Oregon
Portland has many pre-1940 homes on basements or crawl spaces where cast-iron waste lines meet steel water pipe that has narrowed with rust. Newer construction dominates the suburbs, while farms in the Willamette Valley and homes around Bend mostly pump their own groundwater.

Oregon questions
Who licenses plumbers in Oregon?
The Building Codes Division licenses journeyman plumbers and plumbing businesses, and the Construction Contractors Board licenses contractors.
Why is my Portland crawl space wet every winter?
Long rainy seasons saturate the ground. Grading, gutters and a crawl-space sump can help keep water out.
How do I check a plumber's license in Oregon?
Oregon splits plumbing licensing: the Building Codes Division licenses journeyman plumbers and plumbing businesses, and the Construction Contractors Board licenses contractors. A plumbing business must employ a licensed journeyman as its supervising plumber.
