For building managers
Frank Calloway opened the shop on East 38th Street in 1994 with one van and a rule: "Leave every home cleaner than you found it." Today his son Daniel and daughter-in-law Mei run the company the same way — with 14 licensed technicians and the same rule taped inside every truck.
Cast iron stacks, galvanized risers, steam heat — we've worked in over 400 landmarked Manhattan buildings.
Shoe covers, floor runners, HEPA vacuums, and a photo report of the finished work sent before we invoice.
COIs issued same day, alteration agreements reviewed free, board-ready scope letters on request.
Call, text a photo, or book online. A real dispatcher — never a call center — confirms your window within 10 minutes.
Your technician diagnoses the issue and shows you the exact price from our rate book before any work begins.
Licensed hands, protected floors, OEM parts. We pressure-test everything and walk you through what we did.
Photo report, digital invoice, and a workmanship warranty in writing. If it fails, we return free — no arguments.
"A pipe burst behind our kitchen wall at 1:40 in the morning. Marco was at our door on West 74th by 2:25, had the water contained in minutes, and the repair passed our building's inspection the same week. The invoice matched the quote to the dollar."
"We interviewed four plumbers for our Tribeca loft renovation. Calloway was the only one who read the alteration agreement before quoting. Eight weeks, zero change orders, and our board president now uses them too."
"As a property manager I've cycled through a dozen plumbing vendors in 20 years. Calloway has held our 6-building portfolio for the last five because their techs show up, their COIs arrive before we ask, and tenants actually compliment them."
"Our 1911 brownstone still had its original galvanized risers. Daniel walked us through the replacement with photos of similar jobs, phased the work so we never lost water overnight, and left the place spotless every single day."
"Honest to a fault. I asked for a full boiler replacement; their tech found a failed $180 aquastat, fixed it in an hour, and told me the boiler had ten good years left. You don't forget a company that talks you out of a $9,000 job."
"Mei coordinated our entire kitchen gas line upgrade including the DOB inspection. She texted updates at every stage, and the pressure test passed first try. This is what a professional operation looks like."
If our workmanship fails within 5 years, we repair it free — parts, labor, and any wall we have to open. If we're late to your appointment window, the service call fee is waived. In writing, on every invoice, since 1994.
