New Drains Built to Last

Whether you’re renovating a kitchen, adding a bathroom, or building new, proper drain installation determines how your plumbing performs for the next 50 years. ServiStar plans layout, pipe sizing, slope, and venting to California Plumbing Code, then installs with materials matched to the job: ABS, PVC, or cast iron where sound matters.

We coordinate with your remodel schedule, pull the permits, pass the inspections, and pressure-test every new line before it’s closed up, across Los Angeles County and the San Fernando Valley.

Our Installation Process

Drains are the least glamorous part of a remodel, and the most expensive to fix after tile, cabinets, and drywall go in on top of them. Getting the layout, slope, and venting right the first time is the whole game.

We size and slope every line to California Plumbing Code, place cleanouts where future-you will thank us, and pressure-test before anything gets closed up.

Permits and inspections are part of the job, not your homework, we pull them, schedule them, and pass them.

Good to know: drain slope matters: too flat and solids settle, too steep and water outruns waste. We set it right the first time.

1Plan & quote
We review your remodel or construction plans, design the drain layout, and give you a flat written price.

2Permits
We pull LADBS permits and schedule inspections so your project stays fully legal and on track.

3Installation
Drains, vents, and cleanouts installed with proper slope and code-approved materials.

4Test & inspection
Every line is pressure-tested and inspected before walls close, no surprises after the drywall goes up.

 Trustindex verifies that the original source of the review is Google. I put out a request for AC installation quotes on google last week and Michael was one of the first to respond in detail. He paid me a visit about 12 hours after my initial outreach and was so frank in his assessment and pricing that I didn't feel the need to get another serious bid.  That trust was well placed because he and his team executed flawlessly during their installation. Excellent communication throughout the entire process and mission completion one week after we first spoke.  The Servistar team takes pride in their work and business, and I can appreciate that as someone who wants to avoid these expensive endeavors as much as possible.

 Trustindex verifies that the original source of the review is Google. Called this morning around 8:30, and within an hour, Daniel showed up and did a fantastic job fixing our in unit HVAC.

He was kind, courteous and supremely professional (you know, the type of pro who cleans up after he's done working!). Daniel spent at least three hours troubleshooting the issue (turns out we had a majorly clogged line that was causing the system to overflow into the apartment), and then spent another 45 minutes making sure the fix held.

Hope we don't need another repair anytime soon, but if we do, Servistar Plumbing and HVAC (and Daniel) will be the team we turn to.

 Trustindex verifies that the original source of the review is Google. Great experience with Servistar who I called at 10:15 PM on a Thursday for an awful backed up sewer drain clean out and they answered right away, then showed up exactly at 8 AM as scheduled the next morning. They snaked the backed-up drain, used a camera to show the progress and the root intrusion that would need hydro jetting to completely clear through ... via multiple clean out spots. Very thorough. They also fixed a running toilet on the spot with everything they needed. Efficient, professional, affordable, and reliable--highly recommend.

 Trustindex verifies that the original source of the review is Google. My family and I have been using Servistar for probably 8+ years. They have replaced our sewer line, replaced old water pipes to copper at my parents' house and installed all of my family's toilets, fixtures and water heaters. Not only are they reasonably priced but nice people (the owners and workers)! Their work is impeccable and they always get stuff done so fast! Highly recommend them!!

 Trustindex verifies that the original source of the review is Google. Getting drains hydrojetted before a wet winter seemed simple until roots showed up on camera. Mike and Dan tried clearing them, but my pipe junction had collapsed. Typical Studio City hillside soil shifts, I guess. Digging up the yard was costly, but Mike turned a chaotic mess into an easy fix. They had to cut through pavers and concrete to reach the break. You can never achieve a flawless color match on aged patio cement, but their finishing work came  close. Truly great service.

Our drains kept gurgling and backing up into the shower out here in Encino, so we had servistar come take a look. Daniel ran a camera down the line and showed us a massive collapse in the old pipe, plus there wasn't even a proper cleanout access installed. He walked us through the footage and gave us a straight quote for a full sewer line replacement with dual cleanouts. We moved forward with them, and two days later his crew was out front digging. He texted me videos and updates the whole time. They finished the entire replacement in less than two days, and the invoice was totally fair. Definitely using them from now on big or small.

 Trustindex verifies that the original source of the review is Google. Man oh mannnn. Bought an old home, found out the corrosion on the pipes masked the broken parts. When I say disaster I mean disgusting. The Servistar pros saved the day. From sun up to down. Was it a tad more expensive than I wanted to pay for? Yes, but who WANTS to pay for plumbing issues? Nobody. When I say those pipes were done up right. I mean wow!!! Dig the whole ditch went under the house and closed everything up. Unbelievable! I won't trust anyone else.

Water heater completely flatlined on us and finding someone who could actually fix it right away felt like a mission, when we were staring down days of freezing cold showers with a full house. Servistar came through right on time, diagnosed a shot burner instantly, and actually had the replacement parts sitting right there in his truck. He did not try to pressure us into buying an expensive brand new unit we clearly did not need. He just swapped out the bad parts, got everything dialed in, and had hot water pumping again in under an hour. Keeping their number saved.

 Trustindex verifies that the original source of the review is Google. We live in an older house and although the plumbing was redone sometime in the 90's, it still has its set of problems. These problems always seem to happen over a holiday or long weekend lol.

Thankfully I found Servistar a few years back and can always count on them to come out quickly without charging hundreds of dollars extra just for prompt "emergency" service. Michael and Daniel are the absolute sweetest best. Another great plus is my boys love them and will watch patiently and quietly while they work. Hey, free babysitting thrown into the mix always works for me!

I have referred them to so many of my neighbors and they have never disappointed. They have been especially good with elderly neighbors who always get taken advantage of by less reputable companies.

 Trustindex verifies that the original source of the review is Google. Excellent service from Mike, They were able to come out on a Sunday night and took care of a drain blocked by root balls that you could see on camera and that came out on the snake. They provided a very reasonable quote to hydro jet the line the following day. I highly recommend Servistar for any plumbing needs and we will be using them for any future plumbing jobs as well.

 Trustindex verifies that the original source of the review is Google. I have a 20+ year old Bradford White gas water heater that I wanted replaced before next year when electric heaters may be required. Servistar was one of the BW recommended experts. I called up and a couple of guys showed up to look at the job. Subsequently, the manager called up with more information. The two men returned to complete the job efficiently and left with everything neat. They also installed a faucet to a deep laundry sink. I thought they would have to pull the sink out to get at the faucet, but they managed to do it in place. Their quote was the most detailed I have seen for any job. The terms and conditions were easily understandable. I couldn't be happier with the service. They are my plumbers now.

 Trustindex verifies that the original source of the review is Google. My husband is a commercial builder, so we have incredibly high standards for trade work and look at contractor quotes with a magnifying glass. We knew the old cast iron sewer line under our slab was failing, and another company said the only fix was jackhammering our entire hallway floor. I called Servistar to see if we could do a structural epoxy coating instead. The team came out right away, hydro jetted the line, and used a specialized chain tool before applying the coating. Even my husband was thoroughly impressed by how clean their lines were. Their quote was fair after doing lots of research.

 Trustindex verifies that the original source of the review is Google. I ended up having a pipe leak that damaged part of my ceiling during the night. Luckily Servistar was quick to respond and came in asap the next morning and went straight to work! They were both really professional and thorough. They were able to get my pipes replaced within 2 hours and even gave me advice for a different plumbing question that I had. The price was very reasonable as well given the high quality work. Definitely recommend choosing them their the best in the city!

 Trustindex verifies that the original source of the review is Google. 8 days without water; different company spent several hours over 3 different days but could not identify the problem. Michael returned my call promptly on a late Saturday afternoon, Daniel was there shortly thereafter. He found the problem quickly and put a plan in place to our relief! Excellent, fast, friendly, competent service - they have definitely earned our business!

 Trustindex verifies that the original source of the review is Google. We had a full-on sewer line catastrophe, and they saved us. We called him in a panic for a hydro-jet emergency, and he showed up right away. Turns out, the whole sewer line had collapsed. He walked us through everything--tried to avoid a full replacement--but yeah, we needed one. The terrain was brutal, and past plumbers made a mess, but Michael powered through. He got it done in a week, made sure we understood the whole deal, gave us a fair price, and said this new line should last about 150 years. We'll check back in a century, right? Seriously--five stars, and I'd call him again, no question.

 Trustindex verifies that the original source of the review is Google. We needed full replacement of the sewer drain system of our 1600 sq. ft. house. The crew replaced the entire system under the house and out to the sidewalk in 2 days. Very timely and responsive. Thorough clean up after the work was completed. Very professional job, latest equipment, and adequate number of workers. Good price, too.

 Trustindex verifies that the original source of the review is Google. Michael was wonderful! He arrived right on time and his visit was quick and helpful. He solved our main problem in the kitchen within a matter of minutes, and was able to give guidance on next steps for a separate irrigation issue in our back yard as well. Very professional and efficient. Highly recommend! :)
