Birmingham is Alabama's largest city and the economic heart of the metro, covering neighborhoods as distinct as Avondale, Forest Park, Ensley, Southside, Crestwood, and Roebuck. The city's housing stock is among the oldest in the state — many homes in Avondale, Woodlawn, and Ensley were built between 1900 and 1950, meaning cast-iron drain lines, galvanized water supply pipes, and knob-and-tube-era plumbing are still common. These older systems corrode from the inside out, causing chronic low pressure, rust-colored water, and slow drains that no amount of chemical drain cleaner will fix. Multifamily buildings in Southside and Five Points add another layer of complexity: shared stack lines, aging water heaters serving multiple units, and city-required permits for any work touching common systems. We navigate Birmingham's varied permit offices (Jefferson County and City of Birmingham inspections), understand the quirks of older construction, and respond to calls across the city's 99 square miles.
