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!!!

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!

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.

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!

Really happy with the service from Precision Plumbing. 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.

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.

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.

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.

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.

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!

Full Service Plumbing Company in Orange County

Plumbing problems rarely show up one at a time. A small leak can lead to water damage, and an old fixture can hide a failing valve behind the wall. Many homeowners end up calling several companies or hiring a handyman who is not licensed for the job. That usually means mixed advice, repeat visits, and costs that keep climbing.

Precision Plumbing is a complete plumbing provider that handles the whole job with one team. As an insured plumbing contractor, we protect your home and your investment while we work. Our technicians explain your options in plain language before any work begins and leave the work area clean when the job is done. You deal with one crew and one point of contact from the first call to the final check.

Whole Home Repiping in Orange County

Plumbing Repair Services in Orange County

Many Orange County homes were built between the 1950s and 1980s. Their original galvanized or copper pipes have carried hard water for decades. Mineral buildup narrows the pipes, wears down valves, and causes small leaks that grow over time. Low water pressure, rusty water, and a rising water bill are often the first signs.

Our home plumbing repairs start with finding the real cause, not just treating the symptom. We repair leaks, replace worn valves, and fix damaged supply and drain lines. When patching no longer makes sense, we walk you through whole house repiping and what the process involves. You get an honest view of repair versus replacement, so you can plan your budget with confidence.

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.
Big jobs need someone who can handle the whole picture, not just the pipe. Remodels, additions, and full system replacements fall here.
Burst pipes do not wait for business hours. An emergency plumber near me search usually happens with water already spreading across the floor.
Standing water in a shower means the line is partly blocked, not fully. Clearing it at that stage is quick and simple.
Grease coats pipe walls in a layer that cables cannot remove. Pressurised water scours the inside of the line back toward its original diameter.
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.
Water running under concrete does damage you cannot see until the flooring lifts. Detection equipment narrows the leak down without breaking.
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.
Cold showers on day one of a heater problem beat a flooded garage on day three. Repairs cover thermostats, elements, gas valves, pilot assemblies
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.

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

Gas work has no room for guesswork. New lines run to ranges, dryers, fire pits, pool heaters, and outdoor kitchens.
Scale on shower glass and spotted dishes both trace back to mineral content in the supply. Filtration and softening systems.

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

Plumbing Installation Services in Orange County

A new fixture or appliance is only as reliable as the plumbing behind it. Poor connections can cause slow leaks inside cabinets and walls that go unnoticed for months. Work done without the right permits can also cause trouble when you sell or refinance your home. A proper installation protects both the new fixture and the home around it.

Our new plumbing installs cover water lines, fixture upgrades, and plumbing for remodels and additions. We also handle faucet and fixture installation for kitchens and bathrooms, including new shutoff valves and supply lines. Our technicians follow local code and plan each install around your layout. When a job requires a permit, we pull it as part of the work.

Sewer Line Replacement in Orange County

Plumbing Maintenance Services in Orange County

Hard water is tough on every part of a plumbing system. Scale builds up inside fixtures, shutoff valves stiffen, and drains slow down little by little. Most of these issues give small warnings long before they turn into a leak or a backup. Without regular checks, those warnings are easy to miss until the repair bill grows.

Preventive plumbing care helps catch small issues while they are still simple fixes. We test water pressure, exercise shutoff valves, check exposed pipes and connections, and look for early signs of leaks. If your drains are running slow, we can schedule drain cleaning before a full clog forms. Routine visits help your pipes and fixtures last longer and keep working the way they should.

Backflow Prevention Services in Orange County

Plumbing Inspection Services in Orange County

A standard home inspection gives plumbing only a quick look. Most inspectors check what is visible and can miss hidden leaks, failing pipes, or outdated materials. For buyers, that can mean costly surprises soon after closing. Sellers and landlords face the same risk when problems appear in the middle of a sale or a new lease.

A whole home plumbing evaluation gives you a clear picture of the system before you make a decision. We check supply lines, drains, fixtures, the water heater, and water pressure throughout the home. After the visit, we explain what we found and which issues need attention first. Homes over 40 years old benefit from a yearly inspection, while newer homes can usually go two years between checks.

Garbage Disposal Repair in Orange County

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. If your disposal hums but will not turn, contact us and we will tell you whether it can be repaired or should be replaced.
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 do I check if a plumbing contractor is licensed in California?

Use the Check a License tool on the Contractors State License Board (CSLB) website and search by business name or license number. Confirm the license is active and lists the C-36 plumbing classification before hiring any residential plumbing contractor near you. The same page also shows the contractor’s bond and workers’ compensation status.

A handyman can only take on jobs under $500, counting both labor and materials. Any plumbing job at or above that amount legally requires a CSLB license. Hiring unlicensed help for larger work can leave you with little protection if something goes wrong.

For home improvement work, California law limits the down payment to 10% of the contract price or $1,000, whichever is less. Later payments should match the work already completed. A contractor who asks for a large amount upfront is a clear warning sign.

Many plumbing jobs need a permit, such as repiping, water heater replacement, and new gas or sewer lines. Exact rules vary by city, so requirements depend on where your home is located. Unpermitted work can create problems during a home sale or an insurance claim.

A plumber is a tradesperson who does hands-on repair and installation work. A plumbing contractor holds a state license to bid on, manage, and take legal responsibility for plumbing projects. For most residential plumbing services in California, hiring a licensed contractor gives homeowners stronger protection.
