"Ultimately happy with the end result and fair price for our 30ft sewer lateral replacement. Miguel was professional, friendly, and hardworking. However, communication was a bit spotty and we had follow up many times (I understand this is the busy season, though). Also, it was unclear if we were supposed to call 811; we assumed he would, but didn't, and this was an issue as the water line was hit during construction and the city had to come to shut it off on the whole street. It was handled quickly, but would have been avoidable. The project ended up taking much more time than expected, but it was completed in a day, as promised. I would recommend him, but you should be diligent and responsible yourself to make sure all the right steps are being taken."

"They are family owned and operated. Jorge was very friendly and professional, and did everything to help. They even moved the tops of the tanks that must have been over a hundred pounds to a different location and installed Risers. We had to find where the septic tanks were, and what type of tanks, and what was needed to bring the tanks up to code. So we can sell the property. We would recommend them to anyone."

"Jason and his crew performed both exceptionally and professionally on numerous occasions at my residence. Particularly mentionable was the transparency put forth on work explanation versus leaving the customer in the dark. I recommend the outfit to anyone finding themselves in a jam OR on preventive maintenance issues."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

FAQs for septic system installation and replacement projects in Sebastopol, 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.
