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!!!Posted on 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!Posted on 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.Posted on 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!Posted on Google![]()

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.Posted on 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.Posted on 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.Posted on 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.Posted on 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.Posted on 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!Posted on Google![]()

Old pipes rarely fail all at once. It starts with a small leak under a sink, then a stain on the ceiling, then another leak a few months later. Each repair costs money, and the water damage behind walls often goes unseen. Many homeowners also live with low pressure or discolored water without knowing the pipes are the cause.
Precision Plumbing fixes the problem you see today and tells you honestly how the rest of the system looks. Our burst pipe repair service and everyday leak repairs restore water quickly with durable fittings. When the pipes are near the end of their life, we lay out a full repipe with a clear scope and timeline. That way, you can choose between a single repair and a long term fix with all the facts in hand.

Replacing every pipe in a home sounds like a huge project. Many homeowners worry about torn up walls, days without water, and a high price tag. Rigid pipe often needs more wall openings to route around framing and corners. These concerns lead many people to put off a repipe until a major leak forces the decision.
Flexible PEX tubing makes the job faster and less disruptive. It bends around corners, so we need fewer fittings and smaller openings in your walls. PEX also resists the mineral scale and corrosion that hard water causes in metal pipes. Our team plans the route carefully, protects your floors and furniture, and patches the access points when the work is done.
Water spreading across a floor needs prompt attention. Urgent calls include burst supply lines, sewer overflows.
A toilet that refills on its own can waste water throughout the day. Worn flappers and faulty fill valves commonly cause continuous refilling.
A new tap fitted onto seized shutoffs is not a complete installation. Work covers kitchen and bathroom faucets.

Copper, galvanized steel, cast iron, and plastic each have different properties and failure patterns. The material, condition, and location often influence whether a section repair or replacement makes sense.
Pipe in a crawl space is generally easier to reach than pipe inside a finished wall or beneath concrete. Access conditions need to be considered before deciding how much of the surrounding area must be opened.
Precision Plumbing has served Orange County since 2000. More than 26 years of plumbing experience provide useful context when pipe condition, access, and the history of previous repairs influence the next step.
We check the run on either side when it is exposed. Looking at the surrounding section helps identify whether the failure appears isolated or whether nearby pipe shows signs of deterioration.

Water can travel before it becomes visible, so the damp area is not always the source. Meter checks, moisture readings, and other diagnostic methods help narrow down where the leak is coming from.
The smallest practical access point is opened when possible. What the exposed pipe shows helps determine whether the repair should address one section or a longer deteriorated run.
New pipe or fittings are installed according to the condition of the existing system. The repaired section is tested as appropriate before access is closed. Any restoration work follows the agreed scope.
Galvanized steel pipes were common in homes built before the 1970s. Their zinc coating wears away from the inside, and rust builds up as the pipe ages. That rust narrows the pipe and sends brown or yellow water through your faucets. Hot water lines often lose pressure first, since heat speeds up corrosion.
We swap out galvanized lines for modern pipe that restores full water flow throughout the home. Our technicians either remove the old lines or leave them in place, depending on what keeps your walls most intact. We also replace corroded shutoff valves and connections tied to the old system. Many homeowners notice stronger pressure and clearer water from the very first day.
Pinhole leaks are tiny openings that form in copper pipes over time. Water chemistry, hard water deposits, and fast moving water can all wear the pipe from the inside. A pinhole can spray water inside a wall for weeks before a stain appears. One pinhole is often a sign that others are forming along the same line.
Our copper pipe leak repair starts by finding the exact leak and checking the nearby pipe for thin spots. We cut out the damaged section and install new pipe with secure fittings. If you have had several pinholes in a short time, we explain whether a partial repipe makes more sense. For leaks in lines under the foundation, we handle slab leak repair with careful location methods.
The main water line carries water from the meter at the street into your home. In older properties, this line may be galvanized steel or an outdated plastic that turns brittle with age. A failing main line can cause soggy spots in the yard, a water meter that never stops moving, or a sudden drop in pressure. Since the pipe is buried, the problem often grows before anyone sees it. If the main line bursts, shut the water off at the meter and call our emergency plumber team.
We replace main supply lines with durable new pipe sized for your home’s water demand. Narrow trench or trenchless methods help limit damage to lawns, walkways, and driveways. While the line is open, we also check your pressure regulator and main shutoff valve. In homes with hard water, a water softener installation at the same time can help protect the new pipes for years.

Most single family homes are repiped in two to five days, depending on size and layout. Water is often shut off only during work hours, so the home has running water in the evening. Drywall patching may add a day or two after the plumbing is complete.
Check an exposed pipe near your water heater or main shutoff valve. Galvanized pipe looks dull silver or gray, and a magnet will stick to it. Copper is penny colored, and a magnet will not stick.
If your property has a backflow prevention assembly, such as on an irrigation or fire line, your water provider likely requires yearly backflow testing. The test must be done by a certified tester, and the results go to your water agency by a set deadline. Missing it can lead to fines or an interruption in water service.
They can. Some insurers charge more or limit coverage for homes with galvanized or polybutylene pipes because of the higher leak risk. Buyers and inspectors also flag old piping, which can lower offers or slow down a sale.
Yes, most families stay home during a repipe. Work moves room by room, and furniture in each work area is covered or moved aside. Expect some noise and dust during the day, with the house usable each evening.
