Why are our prices slightly higher?

You may notice that Cooper's quotes are slightly higher than average, and we want to make sure you know why that is. By entrusting us with your drain or sewer repair, you're receiving support that goes beyond the repair itself. Our customers choose us because we stand behind our repairs with a 1-year labor warranty and a 100% Satisfaction Guarantee. We also have staff on call 24/7 and have much faster response times for customer support issues than our competition.

Trenchless mainline and drain repair cost factors:


Our initial step involves a comprehensive examination of your plumbing systems, including your main sewer and secondary drain lines. We charge a $119 diagnostic fee to cover our time and labor. For after-hours service, the fee is $219, and on holidays, it's $328. If the repair is relatively simple, the diagnostic fee should cover it.

Video camera inspection

To locate hidden clogs or damaged pipes, we frequently perform video camera inspections. Although this increases your initial costs, it can result in long-term savings by enabling us to determine the most efficient access method. If any issues are identified, these charges can be credited back to the repair costs.

The extent of the damage

If only a small section of your line(s) needs patching or coating, or if your drain lines merely require hydro-jetting, your costs will be lower than if the entire line needs to be replaced. The Cooper Green Team always suggests the most cost-effective solutions for our customers to try to save them as much as possible on their service.

Thanks so much for helping us out. Our shower had an old piece that went bad and David and Aaron came the same day to fix it and alleviate our fears. They quickly diagnosed and repaired. Thank you!
