Louisiana plumbing operates in a unique environment — New Orleans has one of the oldest housing stocks in the South (many homes built in the 1800s–1940s), the Gulf Coast's extreme moisture accelerates pipe corrosion, and hurricane damage creates periodic large-scale replacement demand. Louisiana's recent tax reform (4.25% top rate) improves exit economics.
Louisiana plumbing businesses sell for 2.0x–3.8x SDE. New Orleans metro commands the strongest multiples — active individual buyer demand, unique aging infrastructure demand from New Orleans' historic residential stock, and strong commercial plumbing market from hospitality and tourism (New Orleans is one of the nation's top hotel markets). Baton Rouge (East Baton Rouge Parish) is a solid secondary market with strong residential and oil/petrochemical commercial demand. Shreveport-Bossier City, Lafayette, and Lake Charles are smaller markets.
New Orleans has housing stock unlike any other U.S. city — Creole cottages, shotgun houses, double-doubles, and raised basement homes built from the 1840s through the 1940s are common in Uptown, Garden District, and surrounding neighborhoods. This historic stock has original plumbing infrastructure: cast iron drain lines, galvanized supply pipes, lead service lines, and gravity-fed systems. Plumbing businesses with expertise in historic New Orleans plumbing restoration have competitive advantages that out-of-state businesses cannot replicate.
Louisiana's petrochemical corridor (the 'Chemical Corridor' along the Mississippi River between New Orleans and Baton Rouge) has one of the highest concentrations of refineries, chemical plants, and industrial facilities in the world. Industrial and mechanical plumbing for these facilities — process piping, high-temperature and high-pressure systems, ASME-certified welding — represents specialized, highly compensated work with ongoing maintenance contracts. Plumbing businesses with petrochemical sector relationships have commercial recurring revenue that commands premium EBITDA multiples.
Louisiana's recent tax reform reduced the top income tax rate from 6% to 4.25% effective 2025. This is a major improvement for business sellers — on a $1.5M plumbing sale, this saves $26K in state taxes versus the previous rate. Louisiana sellers now pay approximately 27-28% total effective rate, competitive with Georgia and better than Virginia. The rate reduction makes Louisiana exits meaningfully more attractive than they were historically.
