For a Nassau home job, start with a license check. Consumer Affairs licenses and oversees home improvement firms. It also gives the public a license search. That search is worth doing before you pay a deposit. County rules use a broad meaning for home improvement. The work can include repairs, remodels, changes, conversions, and other work on a private home with up to three family units. Match the name on the bid to the name in the search. Ask what license type applies. Save the result with the bid. A license is not a promise that the work will go well. It is still an easy check that can help you spot a problem early.
Nassau’s definition of home improvement can reach common residential repairs, remodeling, alterations, conversions, and improvements at privately owned one-, two-, and three-family homes. Before handing over a deposit, use the license search to check whether the business is inside the county licensing system. The result will not tell you whether the contractor does good work, so keep checking the bid, contract, references, and project details.
