"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."

"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."

"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

To keep roots from growing into a septic tank. However, there are other steps you can take if existing tree roots are getting close to your septic tank. For one, you can install root barriers, which physically block roots from reaching your septic tank. You can also use chemical solutions in your yard or plumbing system to deter root growth.

Yes, it is possible to drill a well by hand, but it calls for a good deal of physical labor. Drilling a well by hand is best suited for softer soil, and it may not be possible through rockier terrain. For wider and deeper holes, companies with professional equipment make the job much easier.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.

Both materials are suitable for septic tanks, but concrete usually lasts longer than plastic. If you’re buying a new tank, the prices are similar for plastic ($500 to $2,500) and concrete ($700 to $2,000). However, there’s a notable difference in repair prices, with plastic tank repair costs ranging from $150 to $2,000, while concrete repairs are between $700 and $5,000.
