What We Cover

Services We Provide

Burst Pipe Repair

A burst pipe can flood your home within minutes. We respond fast, stop the damage, and replace the damaged section permanently.

Pinhole Leaks

Hard water causes pinhole leaks in copper pipes over time. We locate and repair pinhole leaks before they cause water damage inside your walls.

Full Re-Pipe

Older homes in Ontario and Fontana often have galvanized pipes that corrode from the inside out. We replace entire systems with modern copper or PEX.

Know the Signs

Signs Your Pipes Need Professional Repair

Pipe problems don't always announce themselves with a dramatic burst. More often, the signs are subtle — a gradual drop in water pressure, rust-colored water coming from your taps, or unexplained water stains appearing on walls and ceilings. If you hear the sound of running water when nothing is turned on, that's a strong indicator of a hidden leak somewhere in your system.

A sudden spike in your water bill without a change in usage is another red flag. You may also notice visible corrosion or green patina on exposed copper pipes in your garage, basement, or under sinks. These issues are especially common in older homes across Ontario, Fontana, and Pomona where galvanized steel pipes were standard construction material for decades. If you're seeing any of these signs, don't wait — small leaks become big problems fast.

Our Process

Our Pipe Repair Process

We start by locating the problem. Using pressure testing and visual inspection, we identify exactly where the damage is — whether it's a pinhole leak behind drywall, a corroded section under the slab, or a failing joint in the crawl space. Accurate diagnosis means we fix the right thing the first time, saving you money and avoiding unnecessary work.

Before we touch a wrench, you get upfront pricing. We explain what we found, what needs to be done, and exactly what it will cost. We repair or replace only what's necessary — we don't upsell you on a full re-pipe if a section repair will solve the problem. All work is permitted and inspected when required by your municipality.

We provide this same reliable pipe repair process to homeowners across Ontario, Rancho Cucamonga, Chino, Upland, Corona, West Covina, Pomona, and Fontana.

Local Water Quality

Why Hard Water Destroys Pipes Faster in Ontario CA

The water supply in Ontario and surrounding cities has some of the highest mineral content in California. That calcium and magnesium doesn't just leave white residue on your faucets — it builds up inside your pipes, narrowing the diameter over time and accelerating corrosion from the inside out. Copper pipes develop pinhole leaks years earlier than they should, and galvanized pipes clog with mineral deposits until water pressure drops to a trickle.

If you're investing in pipe repair or replacement, it makes sense to protect that investment long-term. Pairing new pipes with a whole-home water filtration system dramatically slows mineral buildup, extends the life of your plumbing, and improves water quality throughout your home. We can install a filtration system alongside any pipe repair or re-pipe job — ask us about it when you call.
