"Jake took down our old barn and removed two dead trees and relocated our water hydrant. He showed up a week before the job to give my husband advice on removing the electrical panel and get exact dimension for water hydrant. All went smooth in this 95 degree weather. Thanks Jake, you did a great job!"

"Great service. Only downside was a little extra cost for transport of recycled asphalt from Commerce city to northern Colorado. Virus shut down the local sources. Not Tanner's fault though and the the price was more than fair given the distance. Took 8 hours for three loads."

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."

"Tatum Works showed up the next day, gave me a good price to fix my water leak (much better than the other two contractors I contacted) They finished the work faster than expected and restored my yard to the original state. We are so very happy with the entire project with Dustin and his crew. We would highly recommend this company."

Septic Tanks FAQs, answered by experts

While a traditional septic tank requires a leach field for wastewater disposal, it is possible to have a septic system without one. Some alternative systems, which are often used when there isn't enough space for a full-size leach field, include mound systems or sand filtration systems. In a conventional setup, the leach field is essential because it's where the wastewater goes after leaving the tank.

You may notice a septic smell in your yard after it rains if groundwater is entering your septic tank and causing it to overflow. If you experience septic odors after rainfall, contact a licensed plumber. They can construct a drain to redirect rainwater away from your septic tank. 

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

Many contractors offer warranties for parts and labor. Confirm terms before hiring.

Yes, experts handle manual pumping, chemical flushing, and equipment use properly, ensuring thorough cleaning and legal compliance with disposal regulations.
