Everything We Do, Under One License
Dorzi Plumbing & Heating handles the full range of residential and commercial plumbing and heating work across New York City — from a running toilet to a boiler replacement. Filter the list below or search for what you need.
When water is going somewhere it shouldn't, the first job is stopping it. We'll walk you through the shutoff on the phone and get a licensed plumber moving.

Leak Detection & Pipe Repair

No match for that search
We probably still do it — plumbing has a lot of names for the same thing. Call us and describe the problem, or reset the filters below.
Hourly billing rewards slow work. We quote flat rates instead, so the number you approve is the number on the invoice.
We diagnose first.No guessing, no "let's start opening things up and see." We find the actual cause before quoting.
You get options, not an ultimatum.Where a repair and a replacement are both legitimate, we price both and explain the trade-off.
Nothing starts without your approval.The flat rate goes to you in writing. If you say no, you owe nothing beyond any diagnostic fee we told you about up front.
Change orders are conversations.If we open a wall and find something worse, work stops and we re-quote before continuing.
