"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."

"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

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

Yes. Amongst the four most common types of septic tanks—plastic, fiberglass, concrete, and steel—those made of concrete are the most expensive. This is the case for a few reasons, including the fact that they’re very heavy, so pros have to use specialized equipment to install them. However, they’re also incredibly durable, making the price worth it if it’s in your budget.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.
