Clogged drains are one of the most common calls we take across Portland โ and one of the easiest to make worse with the wrong approach. Store-bought chemical cleaners eat away at older galvanized and cast-iron pipe, turning a simple clog into a corrosion problem. We diagnose the actual blockage โ kitchen line, bath line, floor drain, or main line โ and clear it mechanically, with hydro-jetting on standby for grease- or root-heavy lines that keep coming back. In Piedmont (97211), homes built before the 1960s in this area commonly mix pipe materials from past repairs, which is a frequent source of slow leaks at the joints.
