Mold Removal in Tigard, OR: Fanno Creek and Suburban Homes
Tigard grew from about 6,500 residents in 1970 to 54,500 in 2020, and most of its homes date to the 1970s through the 2000s. Fanno Creek runs through the middle of town and floods in the wet months, which Clean Water Services calls natural for the creek.
Homes from the 1970s through the 2000s
The American Community Survey (2020 to 2024) counts 23,877 housing units in Tigard with a median build year of 1988. About 4,900 were built in the 1970s, 4,200 in the 1990s, and 6,900 in 2000 or later, while 14 percent predate 1970. Thirty-eight percent of households rent, and a quarter of homes are in buildings with five or more units.
A house from the 1970s may be on its second or third roof, while one from the 2010s may still be inside the construction-defect window described on our Hillsboro page. The age of the house changes which questions come first.
Fanno Creek through the middle of town
Fanno Creek flows through Portland, Beaverton, Tigard, and Durham on its way to the Tualatin River. Clean Water Services, the Washington County sewer and stormwater utility, says flooding is natural along the creek in the wetter months, especially in winter. In 2022 the agency raised the Fanno Creek Trail under Scholls Ferry Road after flooding that lingered later into summer than usual because of record spring rainfall.
For a house near the creek corridor, the question to ask is how long water stays. Storm water that arrives and leaves within days is a surface problem handled with grading and gutters. A crawl space or basement that stays wet for weeks calls for a different look. Our crawl space and subfloor and gutters and drainage pages explain both.

Do you serve Bull Mountain, Metzger, and Durham?
Yes. Durham is its own city, and Metzger and much of Bull Mountain are unincorporated Washington County. All three are part of our service area along with the city of Tigard.
My Tigard crawl space or basement gets wet near Fanno Creek. Is that normal?
Clean Water Services describes flooding along Fanno Creek as natural in the wetter months. Water that arrives with a storm and drains within days is a surface-water pattern. Water that stays for weeks suggests a high water table or poor drainage and deserves a moisture inspection. The EPA advises drying wet areas within 24 to 48 hours to prevent mold growth.
How fast should I dry a flooded basement in Tigard?
The EPA's guidance is within 24 to 48 hours for water-damaged areas and items. Standing water, wet carpet, and saturated drywall should be dealt with in that window, and sewage or creek floodwater adds a contamination concern that changes what can be kept.
