"My Septic pump had failed. I had already reached out to another septic repair company, but after 24 hours they still could not give me a day they would be available. I called Pavel at Earthworks Solutions and within 3 hours he had Dennis out there to replace my pump. He installed 3 risers and a new drainage pump all in the same day. Dennis did fast good work and I would recommend Earthworks Solutions."

"Initially I had a tank alert go off and called A-Advance Septics to pump my septic system and troubleshoot the alarm. The required services occurred over 2 days (12/1 & 12/3/2020). On 12/1, Matt V. was the service tech that came to locate/dig the tank lids. Matt was very professional in his work when pumping out the two tanks (septic and pump). Matt was very informative and helpful answering my questions, especially when I did not know about the pump tank plus the need to clean outlet baffle filter annually. Thus the need for replacement lid/risers for future access. Ray B. and Doug G. were also very professional and were able to troubleshoot the tank alarm issue and isolate to failed pump (26 years old) and need to be replaced along with new junction box. On 12/3, EJ M. and Doug G. returned to install 3 sets of lid/risers, junction box, and pump replacement. EJ and Doug were very professional in their work and were also informative upon answering my questions. Overall I was very satisfied on the work that was completed and definitely would recommend and call A-Advanced Septics for future service (I liked the feature on the new lids with your company name and phone number embossed, no need to jog my memory or scramble looking for company name or phone number). Thanks, Chester F."

"If you do not make your first call to Hemley's, your making a big mistake. This company stand above the rest for their professionalism, work & business ethic's and their customer service at a fair price. This company should be the first one you call, they will assess and find the best solution which many other contractors wont do. If the scale went to 10, I would give them an 11."

FAQs for septic system installation and replacement projects in Seattle, WA

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.
