What Our Customers Say
Real reviews from real Queens neighbors
Called them at 11 PM when a pipe burst in my basement. They showed up within the hour and had it fixed before morning. Fair price and honest work. This is the plumber Astoria needs.
Maria G.
Astoria, NY
Our water heater died on a Sunday and Astoria Plumbers had a new one installed the same day. They explained everything clearly and the price was exactly what they quoted. Highly recommend.
James L.
Long Island City, NY
Best plumber I've used in Queens. They snaked my main line and actually showed me the camera footage of what was causing the recurring clog. Fixed the real problem instead of just patching it.

Leak Detection & Repair FAQs
How do you find a leak behind a wall?
We use electronic listening equipment and pressure testing to narrow down the location without cutting into walls blindly. This means we open only what's necessary to reach and repair the leak.
Can a small leak really cause damage?
Yes. Even a slow drip behind a wall can lead to mold, rot, and structural damage over time, and it wastes a surprising amount of water. It's always cheaper to fix a leak early.
Do you handle slab leaks?
Yes. We detect and repair slab leaks — leaks under a concrete floor — and can discuss repair options that minimize disruption to your home.
