ConditionalDelaware Division of Revenue (Department …
No Delaware statute licenses routine pool cleaning or water-chemistry service, and Title 24 has no pool contractor chapter. Building or remodeling a pool is construction of an improvement to real property, so the business is a 'contractor' needing the Division of Revenue contractor license — $75 a year with workers' comp and Department of Labor filings, plus the 0.6472% gross receipts fee (30 Del. C. §§ 2501, 2502). Swimming pools are expressly named in the home improvement fraud statute, 11 Del. C. § 916.
Pool electrical work is licensed by the Board of Electrical Examiners: master electricians, master electrician specials for swimming pools, and limited electrician specials for pools in structures of four or fewer dwelling units (24 Del. C. § 1402(13), (15)). A homeowner's electrical permit does not cover swimming pools or hot tubs (§ 1417(a)). Pool heater gas piping is HVACR or plumbing work for a master licensee, and algaecides and other registered pesticides applied for hire may fall under Department of Agriculture pesticide licensing.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Delaware's contractor license is a state Division of Revenue license; it does not test competency and does not replace local requirements. The Division of Revenue says your city and/or county may also require its own business license, and building permits and inspections come from New Castle, Kent, or Sussex County or the municipality where the work is. Electrical work is inspected statewide by Board-licensed third-party inspection agencies (24 Del. C. § 1420), and counties and municipalities may adopt plumbing, HVACR, and fuel gas codes that do not conflict with state licensing law (24 Del. C. § 1832). Pool barrier and construction permits are local.

Delaware offers master and limited electrician 'special' licenses for pools (24 Del. C. § 1402(13), (15)).
Homeowner electrical permits exclude swimming pools and hot tubs (§ 1417(a)), so pool wiring goes to a licensed electrician.
11 Del. C. § 916 expressly covers roofs, siding, driveways, sidewalks, pools, painting, and more; penalties climb from a misdemeanor to a class B felony with the homeowner's loss.

Pending verification: Whether the Department of Agriculture requires a pesticide business license for routine application of chlorine, algaecides, or other registered pool sanitizers by service companies (no category for pools found in 3 DE Admin. Code 601) · Whether Delaware public health rules (Division of Public Health) require a certified pool operator for companies servicing public or semi-public pools · Whether replacing pool pumps and pool piping is 'plumbing services' requiring a master plumber · Whether pool cleaning-only businesses are classified as contractors or under another Division of Revenue business license category · Current value of the $1,500,000 quarterly-filing lookback threshold in 30 Del. C. § 2502(c)(2), which is adjusted annually under § 515 (adjusted figure not retrieved)
