      Trustindex verifies that the original source of the review is Google. We've had a great experience with Precision Plumbing. Most recently, they helped us locate and repair three separate leaks under our concrete slab. They started with a free inspection and did a very thorough job diagnosing the issue, clearly explaining what was going on and what our options were.

Their approach was professional, direct, and honest, no upselling, just practical solutions and clear communication. The work was handled quickly and efficiently. I felt confident in their expertise the entire time. We had also used them previously for a midnight plumbing emergency, and they were incredibly responsive and reliable, one of the only companies willing to come out at that time which is why we trusted them again for this most recent project.

Martin & his team are super knowledgeable, dependable, a great value for what they provide and easy to work with. I highly recommend Precision Plumbing!!!

     Trustindex verifies that the original source of the review is Google. Our main water line sprung a leak and it was such a inconvenience when you don't have proper running water. After finding Precision on Google, I decided to give him a call. He was very responsive and was the first out of 3 plumbers to arrive next day in the AM. He was very easy to talk to and didn't try to up sell like the other ones. His quote was fair and I didn't feel like I was getting ripped off. I would call them back if I need any plumbing services in a heart beat!

     Trustindex verifies that the original source of the review is Google. Our main sewer line had been giving us issues for over a year. Slow drains, weird smells in the backyard, and finally a backup in the guest bathroom that pushed us over the edge. Got three quotes for a sewer replacement for our home in Laguna and these guys came in not the cheapest but definitely the most thorough. The tech ran a camera down the line first and walked me through exactly what we were looking at on his tablet. Turned out we had old clay pipe with two big root intrusions and a partial collapse near the cleanout. They scheduled the work for the following week and got it done in two days. Crew was respectful, kept the yard damage to a minimum, and even reseeded the section of grass they had to dig up. Haven't had a single issue since and I sleep better knowing it's handled.

     Trustindex verifies that the original source of the review is Google. I’m usually very nervous to call any sort of service company. I feel like they always make me feel stupid and rip me off.  My toilet was clogged and I was already embarrassed to contact anyone. When I contacted Martin, he was immediately kind and explained what he would be doing. He did the job perfectly and even left my bathroom cleaner than it was before!

I called them out for a plumbing issue at my home and they showed up quickly, which I really appreciated. The plumber was easy to talk to, explained what was going on in and got everything fixed without any hassle, no confusion, just straight to the point and got the job done right. Overall, solid experience. I’d definitely use them again if I run into any plumbing problems.

     Trustindex verifies that the original source of the review is Google. Was bracing for a hard sell when our 14 year old water heater started leaking. Two other plumbers basically tried to push tankless on me before they even looked at the unit. Called Precision in Mission Viejo and he came out the next morning, walked through both options, laid out the real cost difference and the gas line work tankless would need. No pressure either way. We went with a 50 gallon tank because the math made sense for our family. He pulled the permit, did the install the next day, hauled the old one out, and strapped the new one properly for earthquake code. Straightforward company.

     Trustindex verifies that the original source of the review is Google. Slow drains in pretty much every sink and tub at the same time, which I now know is not a good sign. Called Precision on a Monday morning and they came to the house by 1pm. He camera scoped the line first, showed me a wall of grease and gunk about thirty feet out, and explained why snaking it would only buy me a few months. They hydrojeted the whole line for a fair price. Drains have been running smoothly. Saved as #1 Plumber lol.

     Trustindex verifies that the original source of the review is Google. Both units in my duplex were backing up and I knew it was time to get the main line looked at. A friend in Laguna had used Martin before and said to call him. He came out, scoped the line first so we could actually see what was going on in there, and then hydrojetted the whole thing. years of buildup just gone.

     Trustindex verifies that the original source of the review is Google. These things always seem to happen on the weekend - the outlet from my water heater started leaking. I did a Google search to find a plumber that was open and found Precision Plumbing in Mission Viejo. Within an hour of my call, Martin was at my door. He diagnosed the problem and gave me some options. I chose getting a new water heater and fixing associated fittings.

Martin was back out Monday morning to do the work. They were prompt, professional and friendly. They knew I had a tight schedule and they finished earlier than expected. They double checked to make sure everything was working, including replacing the pressure regulator to the house, which probably saved me from an even bigger future repair bill.

I highly recommend Precision, for your local plumbing needs. Great service and fair pricing.

     Trustindex verifies that the original source of the review is Google. Martin helped us in the past with a clogged drain and this time with a slab leak. Again, I can't say enough good things about his team. From the start, it was clear they really know their stuff and are incredibly transparent and honest. They were thorough with the inspection and took the time to explain everything in detail.

The crew that came to do the repipe was just as impressive. They were hardworking, knowledgeable, and cleaned up after themselves. It was very obvious they knew exactly what they were doing and were great at it!

What Is a Plumbing Contractor?

A plumbing contractor works on the pipes and systems that move water and gas through a building. That covers supply lines, drain lines, sewer laterals, gas piping, water heaters, and fixtures. The work splits into three types. Repairs fix something that broke. Installations put in new equipment or new pipe. Maintenance keeps the system from failing early.

Contractors also carry the parts of a job that sit outside the pipework itself, like permits and inspections on larger work. Most people meet one during an emergency. The smarter time to meet one is before that.

Whole Home Repiping in Orange County

Copper pipe rarely fails all at once. It can thin from the inside, causing pinhole leaks under sinks, behind water heaters, or inside ceilings. Age, water chemistry, and mineral buildup can contribute to corrosion. When leaks keep returning, repairing one section at a time may no longer make sense.

Repiping replaces the home’s supply lines instead of chasing individual leaks. Our crew maps the existing pipe runs first, so you know the scope before work begins. New piping may improve flow where older lines have narrowed from buildup. If discolored water comes from deteriorating supply lines, replacement may improve that as well. The goal is a more dependable system with fewer recurring leaks. As a repiping specialist, we explain the options and costs before starting. Send the age and square footage of the property through Contact Us and we will scope the run.

Your Trusted Partner for Residential & Commercial Plumbing

Our Full Range of Plumbing Services

Every job below runs through the same crew. No subcontractors, no handing your house to someone you have not met.

Plumbing Contractor

Big jobs need someone who can handle the whole picture, not just the pipe. Remodels, additions, and full system replacements fall here.

Emergency Plumbing

Burst pipes do not wait for business hours. An emergency plumber near me search usually happens with water already spreading across the floor.

Drain Cleaning

Standing water in a shower means the line is partly blocked, not fully. Clearing it at that stage is quick and simple.

Hydro Jetting

Grease coats pipe walls in a layer that cables cannot remove. Pressurised water scours the inside of the line back toward its original diameter.

Sewer Line Repair

Sewage backing up into a tub is a main line problem, not a fixture problem. Camera inspection finds the break, the root intrusion, or the collapsed section.

Slab Leak Repair

Water running under concrete does damage you cannot see until the flooring lifts. Detection equipment narrows the leak down without breaking.

Pipe Repair

One pinhole leak in a copper line usually means the rest of that run is thinning too. Repairs cover supply lines, drain lines, and exposed piping in walls.

Water Heater Repair & Installation

Cold showers on day one of a heater problem beat a flooded garage on day three. Repairs cover thermostats, elements, gas valves, pilot assemblies

Toilet Repair

A toilet that runs between flushes wastes water every hour of the day. Common faults are worn flappers, failed fill valves, and broken wax seals.

Faucet & Fixture Installation

New taps look wrong when the supply lines underneath are corroded, and the shutoffs seize. Installation covers kitchen.

Gas Line Services

Gas work has no room for guesswork. New lines run to ranges, dryers, fire pits, pool heaters, and outdoor kitchens.

Water Filtration Systems

Scale on shower glass and spotted dishes both trace back to mineral content in the supply. Filtration and softening systems.

About Us

Precision Plumbing keeps water and gas systems running safely in homes and businesses across Orange County. Honest diagnosis and lasting repairs have driven the work for 26+ years. The aim stays simple: fix it properly the first time, and be the plumber people call again.

How a Job Runs From Start to Finish

Three steps, and you know what is happening at each one.

Step 1: The call

Describe what is happening in plain words. Questions over the phone narrow down the likely cause. Urgent jobs move up the schedule.

Step 2: On-site diagnosis

The system gets tested and inspected before anything is quoted. Cameras go into drain and sewer lines. Electronic equipment helps locate leaks under concrete.

Step 3: The repair

You hear what needs doing and what it costs before work starts. Approved jobs go ahead from there. The work area gets cleared before we leave.

Water Line Repair in Orange County

The water line runs from the meter at the curb to the house, carrying water throughout the property. When it leaks, the yard often shows the first signs: a soft patch of ground, unusually green grass, water near the driveway, or lower pressure at fixtures farthest from the street. Older galvanized steel can corrode internally, while ground movement can strain joints and connections.

Pressure testing and line tracing help narrow down the leak before excavation begins, keeping the repair focused on the affected section. Repair options depend on the pipe type and extent of damage. A localized break may need a section replaced, while widespread deterioration may call for longer replacement. We explain the findings, repair options, and expected costs before opening the ground.

Sewer Line Replacement in Orange County

Some sewer laterals reach a point where repeated repairs no longer make sense. Clay pipes can crack at multiple joints, while cast iron may develop heavy internal scaling that restricts flow. A sewer line that has settled out of grade can hold waste instead of moving it, something cleaning cannot correct. Recurring blockages, root intrusion, or repeated repairs can indicate that replacement is the better long-term option. Two common approaches are open-trench and trenchless replacement.

Open excavation suits lines with accessible runs, while trenchless methods can reduce disruption to driveways, patios, and landscaping where conditions allow. Our team inspects the sewer run before recommending an approach. You receive an explanation of the work, expected disruption, and costs before deciding how to proceed. A damaged section that stops short of full replacement is handled under Sewer Line Repair.

Backflow Prevention Services in Orange County

Water should flow from the main into your building, not back toward the public supply. A drop in pressure can reverse that direction and draw contaminated water into the plumbing system. Irrigation systems, fire lines, pool equipment, and commercial connections can create this risk when they connect drinking water to another source. Backflow prevention assemblies use check valves and components to stop unwanted reverse flow.

These devices can wear out without obvious signs. Springs weaken, valves stop sealing properly, and relief ports may begin leaking. Testing checks whether the assembly still performs as intended, and certain properties must test devices regularly. We repair failed assemblies and replace worn units when necessary. The right solution depends on the device, its condition, and the connection it protects.

Garbage Disposal Repair in Orange County

A garbage disposal that hums without turning may have a jammed mechanism, while one that stays silent could have tripped its reset or lost power. Water collecting inside the cabinet can point to a failed seal, sink flange, or cracked housing. Fibrous foods, grease, and other scraps can contribute to jams and poor drainage. Clearing the obstruction, replacing a damaged splash guard, or resealing the connection often restores normal operation.

Some disposals, however, have reached the point where replacement makes more sense. A corroded housing or repeated mechanical failure can make another repair temporary. Replacement also needs to match the sink connection, available space, and kitchen use. Our team installs the new disposal, connects the drain, checks for leaks, and tests the operation before finishing.

Questions People Ask Most

How much does a plumbing repair cost?

Price depends on the job, the parts, and how long access takes. A running toilet and a sewer line replacement sit at opposite ends of that range. You get a figure for your specific job before any work starts. Call +1 949-235-1188 and describe the problem for a number.

How do I know if I have a slab leak?

Look for a warm spot on the floor, damp carpet with no source, or the sound of running water when everything is off. A jumping water bill with no change in use is another sign. Shut every tap and check the water meter. Movement in the dial with nothing running points to a leak under the slab.

Should I repair or replace my water heater?

Age matters, but it is not the only factor. A newer unit with a failed thermostat or element is usually worth repairing. An older one that has already needed work, or that shows rusty water and tank leaks, leans toward replacement. Rumbling and a shrinking hot water supply are worth getting looked at either way.

Can I clear a blocked drain myself?

A plunger handles simple clogs, and a drain snake reaches a bit further. Chemical drain cleaners are worth avoiding, because they corrode older pipes and rarely clear the actual blockage. When several drains slow at the same time, the problem is in the main line. That needs a camera, not a bottle.

Do you work on commercial buildings?

Yes. Commercial plumbing services cover restaurants, offices, retail units, and multi-unit residential buildings. Grease-heavy kitchens and shared drain systems need different handling than a single-family house. Scheduling can work around your trading hours.

Cities Across Orange County We Cover
