Gresham, Oregon, sits in the western foothills of the Cascade Range and receives an average of 43 inches of rain per year — well above the national average. The city’s clay-heavy soils, aging housing stock, and frequent freeze-thaw cycles create persistent moisture problems for homeowners. Basement seepage, crawl space moisture, foundation cracks, and deck rot are common complaints. Many homes in Gresham were built between the 1950s and 1980s, often without modern waterproofing membranes or proper drainage systems. This creates a strong, steady demand for waterproofing services. The market is moderately competitive, with several established firms operating in the Portland metro area, but few specialize exclusively in Gresham. A locally focused business can carve out a niche by offering same-day estimates, familiarity with city building codes, and fast response times for emergency water intrusion calls.
Demographic trends also support growth. Gresham’s population has increased by roughly 8% over the last five years, with new construction in areas like the Central Gresham district and along the Springwater Corridor. Newer homes still require waterproofing for retaining walls and walk-out basements, while older homes need retrofits. The average household income in Gresham is slightly below the Portland metro median, so price-sensitive customers often seek local, smaller contractors who can offer competitive rates without overhead of big companies. A well-optimized local SEO presence can capture these customers before they search for national chains.
Any waterproofing contractor performing work valued at $1,000 or more (labor and materials) must hold a valid license from the Oregon Construction Contractors Board (CCB). You must register as a sole proprietor, LLC, or corporation, and you need to pass a trade exam focused on waterproofing and moisture control. There is also a business law exam. The current initial license fee is approximately $350, plus a $75 bond requirement. The bond must be a CCB-compliant surety bond of $15,000 for residential work. You must renew your license every two years and complete at least eight hours of continuing education, including a course on business practices and one on construction law.
You must register your business with the Oregon Secretary of State. If you choose an LLC, there is a $100 filing fee and a $100 annual report fee. You also need a City of Gresham business license. The city requires all contractors working within Gresham city limits to obtain a General Business License, which costs about $75 per year. Additionally, you must register with the Oregon Department of Revenue for a state tax identification number and with the IRS for an EIN, unless you operate as a sole proprietor with no employees. For projects requiring structural changes, such as foundation repair or excavation, you will need to pull permits through the City of Gresham Building Department. Permits for crawl space encapsulation typically do not need a structural permit, but you should call 503-618-2525 to confirm.
Oregon law requires all CCB-licensed contractors to carry general liability insurance of at least $500,000 per occurrence and $1,000,000 aggregate. Many clients in Gresham request higher limits. You also need workers’ compensation insurance if you have any employees; sole proprietors may opt out but should still carry coverage to protect against job-related injuries. Additionally, commercial auto insurance is essential if you use a truck or van for your business. Failing to carry proper insurance can result in fines and loss of your CCB license.
