Frank Niesen Company

Frank Niesen Company has kept Cincinnati comfortable since 1884, building over 140 years of continuous service as a family-owned contractor. Based in Cincinnati, Ohio, the company holds full licensing, insurance, and bonding while employing master plumbers to handle everything from routine repairs to complex remodels. Homeowners rate the company at 4.0 stars across 26 verified reviews, with the business open Monday through Friday from 7:30 AM to 5 PM.

What distinguishes Frank Niesen is their ability to handle five trades under one roof: plumbing, heating, cooling, electrical, and bathroom remodeling. This multi-trade capacity means a single callback handles interrelated problems across systems, something single-trade contractors cannot match. All work carries a workmanship guarantee, and emergency service availability provides peace of mind for sudden failures.

Reviewers repeatedly name specific technicians who delivered during difficult moments. Mike arrived the next day for preventative maintenance and resolved a faulty repair part at no charge when the homeowner reported a problem three weeks later. Dave and Grant replaced an underground water service line at the street curb, filling the excavation so neatly that was barely visible afterward. Jared guides real estate clients through the buying and selling process, keeping agents and homeowners informed from estimate to completion.
