"Jordan was awesome! He initially sent one of his guys out to check for some gurgling and sediment in our plumbing in the basement. They took a good look and found some grading issues with our pipes. Jordan followed up with me after and then committed to coming out himself to determine options. Throughout it all he was very communicative and extremely knowledgeable. We discussed some options and moved forward with the one that made the most sense. The issue was addressed and Jordan followed up later on to make sure everything was still good. Highly recommend Jordan and team dr.drain!"

"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."

"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."

"The plumber, John, was outstanding and reassured us that the problem was taken care of. He also explained what had caused our main drain to block and offered some suggestions on how to prevent it from happening again in the future. I was also so pleased at how quickly they were able to come on a Sunday night. Excellent customer service. I highly recommend."

Customers say: Terrific value

"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."

Septic Tanks questions, answered by experts

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

There are a few things that can make your drain field fail. These include driving or parking vehicles or heavy machinery on the field, excess sodium in the soil, or having a high water table. You can prevent failure by ensuring your installer checks that your chosen location is suitable for a drain field and properly maintaining your system with the help of a professional.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.
