Goldak

What Goldak does

Goldak, Inc. is a US-based original equipment manufacturer (OEM) that designs, engineers, and manufactures underground locating and leak detection equipment. Founded in 1933 and headquartered in Sylmar, California, the company produces pipe and cable locators (Triad 2310 series, 902 Splitbox, 902 Subscanner, 5600-SI), water leak detectors (777-A, 777-B with NE-77 noise eliminating microphone and 777 MAX upgrade), valve and metal locators (720, 7200XP), EMS marker locators for gas, power, water, cable TV, telephone, and sewer utilities, and a full SR Series of sondes and transmitters. The core technology relies on electromagnetic signal transmission, acoustic sensing, and correlation methods, protected in part by the company's patented Super-Inductor (SI) antenna system. Goldak also serves as the exclusive North American distributor for Sewerin GmbH's professional leak detection and correlation products, including the AC200 Correlator and Aquaphon acoustic system.

The company operates four revenue streams: sale of Goldak-branded hardware, distribution of Sewerin products, contract locating field services (gas leak detection, water leak detection, pipe locating, utility location, and video inspection), and ongoing product support, training, and equipment repair. Pricing spans from $15-$125 for consumables and accessories to $400-$2,000 for standard locators, $2,000-$4,000 for professional leak detection and advanced pipe/cable systems, and $5,000-$22,267 for Sewerin correlator systems, with financing available through PEA Solutions. Go-to-market is hybrid: direct enterprise field sales targeting utility companies, municipalities, construction firms, and plumbing professionals, supplemented by a transactional e-commerce storefront at goldak.com.

Goldak's customer base spans water utilities, gas utilities, construction and excavation firms, plumbing service companies, and facility/property management organizations. The company is privately held with 11-50 employees, no disclosed parent company, no venture or private equity funding, and no recorded acquisitions. Its competitive position rests on nearly 100 years of brand heritage, patented antenna technology, US-based manufacturing, a field-technician-to-R&D feedback loop, and the exclusive Sewerin distribution relationship.
