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 Linnton (97231), older service lines around Portland are frequently undersized for modern fixture counts, which shows up as weak pressure at multiple taps at once.
