"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."

"We had a backup in our main and these guys came out within 30 minutes on a Sunday. They cleared the blockage for us and even offered to come back and clean it if it happened again within 30 days (which it did, and they came out immediately to clear it again). They were very helpful and I would highly recommend them for anyone needing a plumber."

"I highly recommend Seamus, Kellen, and their team at Doone Brothers. They did my septic as well as my full site excavation/grading/driveway project. My site is very steep and challenging. I found them to be hardworking and fair. They went above and beyond with their communication and effort on my project and Iâ m super grateful to them for the work they did."

"Matt and Alexander responded really quickly to my request and were able to complete the work in my bathroom the following week. They replaced faucets and light fixtures and also installed a niche in my shower. I’m super pleased with the quality of work and will use them again for future house projects."

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.
