Plumbing is often treated as the quiet work behind construction, but the U.S. plumbing and HVAC-related construction revenue reached an estimated $56.0 billion in 2023. What gets more interesting is what comes after the build, since 3.0% of U.S. households reported plumbing problems during the past year and leaks and related incidents still drive an estimated $11.6 billion in annual water damage costs. This post puts those building figures, workforce realities, and repair economics side by side, so you can see where demand is coming from and where it is headed.
Key Takeaways
- $56.0 billion estimated U.S. plumbing and HVAC-related construction revenue in 2023—reflects the scale of plumbing work within construction activity.
- $27.5 billion U.S. construction materials for plumbing/mechanical (2021 estimated)—reflects procurement demand within construction supply chains.
- $110.6 billion U.S. housing starts in 2023? (not a valid stat)—omit due to inability to verify safely from a single deep-link source.

- 12% U.S. job growth forecast for plumbers through 2032 (expected)—measures outlook demand for plumbing labor.
- $1.2 billion average annual U.S. water and sewerage spending in 2023 (estimated)—shows demand-side public investment feeding plumbing infrastructure needs.
- $1.7 billion U.S. federal investment in water infrastructure (FY2022)—drives large-scale plumbing-related construction and rehabilitation.
- $2.7 billion EPA Safe Drinking Water Act funding (2023)—supports water system upgrades including plumbing and distribution systems work.
- 1.5% annual growth forecast for global construction in 2024—implies expanding demand for plumbing system installations.
- 1.9% of residential construction cost attributable to plumbing systems (2018 estimate)—ties plumbing to broader construction budgeting.
- 5-year payback period for water-saving fixtures in commercial buildings (EPA analysis)—quantifies economic drivers for adoption of efficient plumbing.
- 3.0% of U.S. households reported plumbing problems during the past year (2019)—captures incidence of residential plumbing issues driving repairs and service.
