"Our main sewer line backed up on Saturday afternoon. After a bit of research on Angie's List, I called The Drain Company around 3:00 and was given a verbal dollar estimate ($145 minimum on the weekend) and a time estimate of between 5:00 and 8:00 PM. I received a call from Kent at 5:15 PM that he was on the way. He arrived about a half an hour later. He sent the snake down the line, and it soon cleared the clog. He left it going for several extra feet to make sure to clear any additional roots all the way to the street.

They were friendly, polite, and knew the job. They were on time and met the agreed on price. I would not hesitate to call them again!"

"Our experience with the Drain Guys went very well. As with all service providers, the previous jobs they're scheduled for sometimes delays their next job which is what happened with us. But, once Eddie was on the job, he took care of the problem and us very well.

"The Friday before Thanksgiving we discovered large puddles in our laundry room and hallway. My dad, ever the handyman, tried to find the leak but grew distraught when he realized the water was coming from inside the walls and not our washing machine. That night, not wanting to chance my dad trying to fix it or worse, a friend of a friend, I became a member of Angie's list and looked for a reputable plumber nearby open on the weekends.
I called Saturday morning and they arrived same day Saturday afternoon (I told them it wasn't a major leak). They looked everywhere for the leak, moved our washer and dryer, opened up the wall, etc. They were able to isolate it to the hot water and advised us to leave the hot water off at night when the water pressure increased. Sunday they charge double, so we opted to continue on Monday. On Moday, first thing in the morning 8AM  they brought in a specialist with the fancy audio leak detection device seen on their website, which was kinda neat. A manager came by and told us there were a few other issues, but it turned out we just needed a new water heater (ours was over 10 years old, installed by my father and not up to code) and a pressure regulator. We were quoted a bit over 5k for everything, which was around how much we thought it was going to be, so that worked out. They came back on Tuesday at 8 AM and worked all day and restored hot water by 6. Thanksgiving was saved~! Hurray~! 
Service was excellent, everything was up to code. They taped down crate paper on the floors of the places they worked in, replaced the drywall, bolted everything into place, moved a bunch of heavy stuff without help--everything looked great when it was done. We're all pretty impressed and would use Richco again in the future.

"Two service Techs, Daniel and Kevin, came by the same day i called regarding a clogged sewer line. They were very pleasant and personable which put me immediately at ease. They performed an inspection and showed me a live video feed of my sewer line, indicating where the roots were growing in that caused the clogging. 
They recommended hydrojetting due to the size of sewer, and scheduled a visit the following day.  The next day the same techs came by and cleaned out the sewer line via hydrojetting. Afterwards they did another video inspection and showed me their results. They were professional, communicative, clean, and very pleasant to deal with.

"I had to leave before he was through. When I came back, I wasn't here to give him permission. There was a hose connection that needed to be replaced. He didn't replace it. It was going to be $100 more. I wanted a pan under it and he didn't have one. My son had to help him carry it in. I don't think I would use him again. He came from a long distance. There were no additional costs. I went over to the hardware store to buy the part that he needed which he wanted to charge me $100 for. He was an older man. I felt bad that he even had to carry it. That's why my son helped him to carry it from his truck.  When I hire somebody, I don't want to feel bad about them doing the job. He didn't complete the work. He didn't have the parts that I wanted."

"I first met Tony, owner of Nexxus Remodeling, soon after his lead hardwood flooring installer had come to check out my home so they could send me an estimate. My project was to rip out all carpet in my upstairs, and on the stairs from the 1st floor. Even before I had received all bids I’d sought from him and other contractors, Tony found out the floor I’d intended to buy was out of stock. He arranged for me to go to a showroom that has the best inventory and selection I’d seen in my search, and he met me there to personally assist me to find flooring I liked just as well as my first choice. I was soon able to determine that Tony’s bid was very comprehensive and reasonable, but his efforts to help me before even being hired had impressed me just as much. If you want to hire a contractor who will go to extreme lengths to ensure you end up a totally satisfied customer, Tony. He said from the beginning that he wouldn’t consider my flooring project completed until I felt that every detail had been attended to, and he meant it! Tony personally checks in frequently to monitor the project. His crew does it all (carpet removal and disposal; installation of hardwood flooring, moldings and risers; carpentry; removal and replacement of doors and furniture; and, clean up after each days work). Not only that but they removed a washer and dryer that had konked out, and brought them downstairs onto my patio, AND then they cleaned out a laundry area that had at least 25 years worth of lint and dust built up in it. I sincerely recommend Nexxus Remodeling for your next home renovation project - not just for hardwood installation (they do it all!)."

FAQs for septic system installation and replacement projects in Los Angeles, CA

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
