From full pipe rehabilitation to a stubborn kitchen clog, here's the plumbing work that keeps the San Gabriel Valley running — shot for shot, no filler.
Our trenchless pipe lining technology lets us rehabilitate deteriorated or cracked pipes without tearing up your yard, driveway, or landscaping. Using cured-in-place pipe (CIPP) methods, we insert a flexible liner and cure it in place to form a seamless, structurally sound pipe within your existing one. The result: a like-new pipeline with a lifespan measured in decades, at a fraction of the disruption of dig-and-replace — ideal for the aging clay and cast-iron lines common throughout the San Gabriel Valley.
When a line is too far gone for lining but you still want to avoid a full excavation, pipe bursting is the answer. We pull a bursting head through the old pipe, fracturing it outward while simultaneously drawing a brand-new, seamless HDPE pipe into place behind it. One pass, two jobs done — a new pipe installed underground with minimal surface impact. Especially effective on collapsed or root-infiltrated sewer lines.
A slow drain rarely fixes itself. We get to the root of the problem — sometimes literally — whether it's grease buildup, hair, mineral scale, or tree root intrusion. Using professional-grade hydro-jetting and mechanical augers, we clear blockages thoroughly and inspect the line so you're not dealing with the same issue two weeks from now. From kitchen sinks to main sewer lines, we handle drains of every size.
Endless hot water, on demand. We install and service tankless water heaters that ditch the bulky tank for a compact unit that heats water as you use it — saving space and energy over the life of the system. Pair it with a whole-home water softener and you'll notice the difference in everything from your skin to your pipes, which stay cleaner and last longer without scale buildup from SoCal's notoriously hard water.
Behind The Wrench
We built this company around a simple idea: fix it right, fix it fast, and don't tear up someone's property to do it. That means investing in trenchless equipment most crews don't carry, training techs to diagnose with a camera before they ever pick up a wrench, and answering the phone ourselves — day or night.

The Fine Print, In Plain English
We give you a real arrival window — and we honor it. No all-day guessing games waiting on a truck that never shows.
We leave your property exactly how we found it — or we come back and fix that too. Your driveway and landscaping are not collateral damage.
You'll know the full cost before we touch a single pipe. No surprise invoices, no padded line items, no games.
The Credits Roll
Trusted by hundreds of San Gabriel Valley homeowners who needed it done right.
Had a sewer backup on a Sunday night and they actually picked up the phone. Crew was at my place within the hour, found the blockage with a camera, and cleared it completely. Total pros.
Marcus T. — Covina, CA
They relined my main sewer line without digging up my entire backyard — I honestly didn't believe it was possible. The job was clean, fast, and the price was exactly what they quoted up front.
Sandra R. — Glendora, CA
Finally made the switch to a tankless water heater and I wish I'd done it years ago. The install was smooth, they explained everything, and I've had zero issues. Very happy with Top Notch.
