"We have always had great results with ReddiServices! David Wilson was our technician and he did a great job. He was extremely friendly, answered all of my questions no matter how big or small. He did a great job replacing our old steel pipes to new PVC. Excellent customer service."

"10/10 would recommend. Bryan is professional, knowledgeable and maintains excellent communication with his customers. We had an incredible experience working with KCS to resolve issues with our septic system that had been installed by a different company before we bought our house. Due to our budget and the nature of our septic problems, we had the work on our system done in two phases, and from the first time he came to our house 9 months ago, through the completion of all the work we needed to get the system functioning correctly this week, Bryan was so helpful. He made us feel comfortable as we dealt with an unfortunate situation. He and his team excavated and reset our pump tank, completely redid the manifolds for our drip fields and corrected several other issues with the pipes going into and out of the septic tank. He is an expert in his field and never hesitated to share his knowledge with us, to answer any questions we had about the situation we were dealing with or to increase our understanding of our system. He is prompt with communication and never made us feel like we were burdening him with questions as we navigated the best way to resolve the circumstances we were working with. When he first came to our house and looked into our pump tank, his knowledge and experience allowed him to accurately predict what sort of issues we’d find throughout the rest of our septic system. His estimates regarding the cost of work needed also proved to be accurate and fair. The crews that he had out for each of our jobs were professional and worked quickly to get the jobs done well. After 4 years of battling a faulty system plagued by issues, we finally feel at ease and confident that we have a quality system that has been installed correctly. I’ll recommend Bryan and KCS to anyone I know that is need of septic work."

"They replaced our driveway, walkway and repaired a crack in the garage floor. They were very professional and knew what they were doing. They made suggestions on the curve in the walkway which turned out very nice. I would recommend them."

"Hector was amazing from start to finish. Prompt and shows up himself to estimate the work, which was much more reasonable than the 2 other quotes we received, and does a great job through until the end. I have used him three times (for clients anbd myself) and has been consistent every time. He listens, gives quotes quickly, and schedules the repair promptly. Could not recommend more highly, he will be my sewer and septic guy for the long-term!"

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

FAQs for septic system installation and replacement projects in Leavenworth, KS

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.
