1 cited review
“These guys are really great. My wife and I had an overflowing water heater...late at night...and on a weekend. Big Apple are one of the VERY few companies that will come out after-hours, of which they did. Our technician was Jacob, and he took care of us that same night. The water heater needed replacing, and he went and got a replacement & installed it. The poor guy was up late to finish the job (finished up around 2am)”

Red flag
Owner responded to 1-star pricing review with emails calling the reviewer a 'liar, slumlord' — documented misconduct pattern.
“They wanted to charge me $247 for a "diagnostic fee", which was in addition to the $89 "service fee" I had already agreed to pay. EDIT: After this post he started emailing me calling me a liar, slumlord, etc. Not professional in the slightest.”

The evidence — in reviewers' own words
Critical
“I had a slow drain in my basement due to roots growing in a main drain pipe heading out to the street. Protip: Don't plant huge trees over ground that has PVC pipes in it. I'm a Realtor and see this far too often. Big Apple booked us for the next day and showed up on time with great communication through texts. I knew there was an $89 service fee. The technician decided the pipe needed to be snaked, as suspected. …”
“Even though they advertise that they can provide estimates on Yelp, this information is wrong. They do not provide quotes "over the phone." Needed a quote on labor for a toilet fill valve replacement but was messaged to call the office. So do not even bother messaging them for help. It is just more convenient to book through an app than calling in. Waiting for this plumbing company to catch up to 2021.”
“My husband and I had a bad experience with this company. Our hot water heater broke. We called a friend in the roofing/construction business and he recommended this company. The tech who came out was very nice and did his job. We were shocked at the price at which we were told was their baseline price to remove, pick up and install a new water heater. The tech called his boss who is the president of the company. All …”
Positive
“The drainage system was assessed thoroughly, reducing future risks. The work reflects a high standard of execution.”
“Clear explanations, precise timing, and effective solutions made this service stand out distinctly.”
