Portland General Contractor & Damage Restoration | JR Johnson

Foundation seepage from groundwater intrusion is a frequent issue in Portland, especially during wet months. Our team begins with a thorough water intrusion diagnosis to find the source. We then perform water extraction, dry out affected areas, and repair any drywall damage caused by the moisture. For long-term solutions, we address the building envelope, repairing or replacing seals and barriers to prevent future seepage. Our in-house crew manages every step, ensuring your basement or crawl space is restored and protected.

Biohazard cleanup covers the safe removal and sanitization of dangerous materials like blood, bodily fluids, or chemical spills. This service is often needed after accidents, crime scenes, or unattended deaths. Our team follows strict safety protocols, uses proper protective equipment, and ensures all waste is disposed of according to Oregon regulations. We handle the job with discretion and professionalism to restore the space safely.

Absolutely. As a general contractor, we manage building additions and deck construction together, often as one project. If you're adding a room, we can design and build a deck that connects to the new space seamlessly. By keeping the work in-house, we coordinate the foundation, framing, and finishing to match your home's style. We serve Portland neighborhoods like Sellwood and Irvington, ensuring the new structure meets local building codes.
