We use public records to help you make a shortlist. They show what a contractor has filed and where they have worked in Columbus, OH. They can't tell you whether someone will be right for your home.
28% of the 2,654 firms on the Columbus, OH permit file match an active license in the Ohio OCILB public roster of current electrical, HVAC, hydronics, plumbing and refrigeration contractor licenses. Our match can miss a firm that files under another name, so a missing match is a reason to check, not a finding.

The middle value recorded on this contractor's matching permits. It's a permit value, not a quote or the final price. Ask for a written estimate.
Matching Columbus, OH permits in the most recent year of our data. It shows recent recorded activity here, not every job the company did.
For contractors with at least 5 permits a year or more old, the share that reached final inspection approval or a certificate of occupancy. A permit can stay open because of paperwork or timing, so this isn't a workmanship grade.
How long their permits take from issue to the date the record reached final approval, compared with other Columbus contractors in the trade. Shown for firms with 10+ permits.
Matched by name against the Ohio OCILB public roster of current electrical, HVAC, hydronics, plumbing and refrigeration contractor licenses. Name matching can miss a license, so always check the number yourself.
About the ranking: The score combines how much of this exact work a contractor has on record, how often their older permits reached completion (where we can measure it), how well their usual job size matches your budget, how recently they've been active, and how much of their work is near you. A measure we can't calculate is left out rather than guessed, and a thin record pulls the score toward the middle. A contractor whose matched license has a problem is listed after everyone else. You set the weights with the sliders on every list.
Columbus, OH specifics: Electrical, HVAC and plumbing permits carry a $0 job value, so those trades show counts, completion and speed but no typical cost or price comparison. On homes the city files roofing, siding, windows and doors under one permit type, so they are ranked together as Roofing, Siding & Windows; only about a third of those permits are ever finaled and large firms differ sharply in whether they call for the final inspection, so that trade shows completion but no speed. Additions show no price comparison because no firm has 20 priced additions. The finish date is the date the permit record reached its final status, not an inspection date. Basement Waterproofing has only 12 firms and one of them holds most of the permits. The contractor is the applicant business on the permit, which is sometimes a builder or retailer filing for a subcontractor; permits filed by homeowners or under a person's own name aren't ranked. The OCILB roster lists current licenses only and no first-licensed date, so years licensed isn't shown, and roofers, remodelers, waterproofers and home builders need no Ohio license. Locations are by ZIP code. Some firms appear under two spellings.
