"The company showed up when they said they would and completed the job within the time frame that they stated. Communication was a little rough with the field, but communication with the office was very responsive. Considering the extent of the work and the constraints within which they had to work, there was remarkably little collateral damage done. Unfortunately I was not able to witness the work before it was covered up and so I cannot comment on the quality of the installation, but can say that the company did a good job protecting the surrounding landscaped areas and seemed contentious and thoughtful in their approach to the work. I would definitely work with them again."

"Waldo and his guys were honest and straightforward in evaluating my sewer problem: they told me what needed to be done and as importantly, what didn't need to be done. Another company came out and stated that the entire line had to be replaced, even though most of it is PVC since a remodel in the 90s. Waldo answered my questions directly, telling me how they would approach it and what could happen that would involve more work and therefore most cost. Even with these caveats their bid was anywhere from 20 to 60% cheaper than other bids we got. They sent me a video of the completed work showing replacement of the broken pipe as well as the rest of the sewer line. With the five year warranty, I feel peace of mind and confidence that they will stand by their work. If there is any downside, it's that they are very busy so sometimes it takes a bit to get back to you. But I never felt put off or neglected. Definitely will use them in the future for any plumbing work that comes up."

"They helped me find the right people to help me with the engineering and get the job done quickly. They were able to quickly adjust their schedule to accommodate our urgent situation. They also saved me thousands doing there Own assessment and questioning others who wanted to do 3x of the amount of work and essentially replace entire system which was necessary."

FAQs for septic system installation and replacement projects in Denver, CO

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.
