Resiidential Remodeling & Restoration Experience

With over 30 years of combined experience in Portland, Oregon, working on home remodels, historic restorations, and new residential construction, we understand the structural challenges that come with older homes and modern upgrades.

Through years of working alongside architects and remodel contractors, we have learned how to design plumbing systems in the field without compromising structural integrity — especially in homes built over 100 years ago.

Running 3-inch ABS drainage through 2×4 walls — particularly exterior walls — requires careful planning and real-world problem solving. We design plumbing layouts that meet code while protecting the structure, preserving framing, and maintaining the strength of the building.

Our experience allows us to adapt intelligently in remodel situations where structural limitations demand precision, not guesswork.

For properties requiring full service upgrades, we also provide main water line replacement services.

Remodeling plumbing in older Portland homes is not the same as installing pipes in new construction. In many remodel projects, only the visible finishes are updated — but the hidden systems behind the walls often remain outdated.

Our approach is different.

With real-world remodeling and construction experience, we evaluate the entire plumbing system — from underground drainage to final fixture installation. We understand framing limitations, structural integrity, venting design, and how to upgrade older systems without compromising the home.

In remodel situations, you don’t always have the luxury of starting from scratch. That’s why proper planning, layout adjustments, and code compliance are critical — especially in homes built 50 to 100+ years ago.

At JAM Plumbing PDX, we don’t just replace what’s visible. We design systems that work properly behind the walls — today and long term.
