"The pipes were PVC and the snake damaged the pipe and we had to dig up and replace the line. At the time, I did not consider that they had caused the break. But, in the end, knowing the whole story, I realize it was their fault. However, the tech whe responded to my call was friendly, took his time, and did his best to resolve the problem."

"Dan and his team were incredibly responsive, especially when I discovered a second leak while they were replacing the hot water heater. They also, quite literally, saved my life and my neighborhood when they caught a gas leak, I didn't notice, helped identify exactly where it was coming from and hooked me up with folks who came out immediately to repair"

"had an excellent experience with Bluamari Contracting Services LLC. They serviced and repaired my water heater and also installed our new breaker box, and the quality of their work was outstanding. The team was professional, knowledgeable, and took the time to explain everything clearly. The work was done efficiently, safely, and with great attention to detail. It?s hard to find contractors you can truly trust, but Bluamari exceeded our expectations. I highly recommend them to anyone needing reliable electrical or plumbing services."

"The job which was complicated replacing 2 Old Cesspools with tanks and a drain field. They gave me a date months out but showed up as scheduled. They handled all the permit work and left me with a freshly seeded lawn that came up great. This is a family business generations old. I was very pleased with a job well done. Highly recommended !"

"Michael and his team were professional, communicative, and most importantly got the job done! Contractors have a stereotype that they never get back to you or ghost you. Not the case with Michael who made sure to give me a call or txt anytime. He worked with the local supplier to order a custom Andersen window and in the meantime, stopped by multiple times to provide advice and estimates. On the day of the job, everything was completed in a timely manner and they made sure to clean things up after. They replaced a large window without any mess, installed a storm door, and patched up leak damage. They also got on a high ladder three stories high to caulk the exterior for our townhouse. Would highly recommend and definitely work with them again! Thanks Michael!"

"Mike came to my house within a few hours on a Saturday afternoon, because I told them I have been without a sink, dish washer, etc. Told him I had new counter tops installed and he actually came with me on a 10 mile trip to Lowes to make sure I got all the correct and necessary parts to get the job done.  Then he came back the next night on a Sunday to fix one more thing with the sink at no charge.

Very friendly, trustworthy, least of all inexpensive."

FAQs for septic system installation and replacement projects in Philadelphia, PA

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.
