"They were able to get the job done within expected timeline but did not pay attention to the details. They hurried the pipe that needed to be left at a slight incline to drain, under the gravel. They didn?t confirm a time or way of payment collection and just showed up at home, followed my husband in garage asking fir money which I was supposed to pay and I was in communication with the company. I communicated and paid them next day but again got a payment request via home advisor a few days later. I consider that an unpleasant experience"

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

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

Permits command adherence to health and environmental standards, with submission crucial for new system installations or extensive modifications.

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.
