Delaware Plumbers

Hiring a Plumber in Delaware

Buildermuse currently lists 10 plumbers in Delaware, averaging 4.9 stars across 9,310 verified Google reviews. That is an unusually strong field — when nearly every firm clears 4.8 stars, response time and availability become the real differentiators, so call two or three rather than only the top result. Most of the crews above operate out of Wilmington, Townsend, and Frankford.

Delaware licenses this trade at the state level: the Plumbing credential is required for all work, regardless of project size. State license required for plumbing work. Verify any license directly with the Delaware Division of Professional Regulation at (302) 744-4500 before signing a contract.

Labor is the biggest line item on most bids, and the Delaware market sets the floor: construction workers here average $36.02 an hour — about $74,932 a year — across 24,563 workers statewide, per Bureau of Labor Statistics data. Use that figure as a sanity check when comparing quotes — a bid priced far below market labor rates usually means subcontracted or uninsured crews.
