Contractors and engineers see a marketplace that is stabilizing, even if margins remain tight. “We remain cautiously optimistic about plumbing industry market conditions in 2026,” says Jason Pritchard, president of the Plumbing-Heating-Contractors—National Association (PHCC). He notes that while uncertainty remains, moderate growth is expected for plumbing and HVAC contractors, though high prices driven by tariffs and inflation will continue to shape consumer behavior.
