About J & J Mechanical
J & J Mechanical operates as a general contractor serving Jersey City, New Jersey, and maintains regular weekday hours from 8 AM to 5 PM, Monday through Friday. With a current rating of 3.0 stars drawn from two customer reviews, the company is a smaller operation that has earned mixed feedback from the clients it has served. J & J Mechanical is available to property owners and commercial clients who need a local contractor familiar with building standards in Hudson County.
Because no active website was available at the time of this review, specific brand partnerships, unusual specialties, or workmanship guarantees could not be verified for this listing. Homeowners should confirm directly with J & J Mechanical which particular trades or project types the company handles on a routine basis before engaging the firm.
Leonardo Switzer-Perez contacted J & J Mechanical seeking HVAC assistance and was informed that the company does not provide that service. That experience underscores the importance of asking upfront whether a general contractor handles the specific trade or project type a homeowner needs. Switzer-Perez specifically noted that the absence of clear service information online led to a wasted inquiry.
What Customers Say
Both reviews on record were submitted by homeowners who contacted the business seeking services. One reviewer received a direct refusal for HVAC work, and the other review remains on file contributing to the current 3.0-star average.
