"For those of you who are looking to have demolition work done, I highly recommend Bronco Demolition. I had them demo my pool in May 2025 and they did a great job. The owner, Eddie, was very communicative and explained the process thoroughly-- and he really went above and beyond to make sure everything was done correctly. And they are reasonably priced too. Needless to say, I was very pleased with the outcome. Thanks Eddie!"

Customers say: Quick response

"I received two other estimates before contacting Home Advisor and thus Rene from Environmental... I knew from the moment that I spoke to Rene that I liked him and would most likely hire him. He was presentable, listened to my ideas and then offered up some of his own for what he thought might look nice and work well for my project. He spent at least An hour here, taking measurements and plotting the job and returned the following day with his estimate. Rene was definitely not the cheapest however he was definitely the most thorough, precise and professional... He busted his butt over the next two weeks and knocked it out of the park! I will most certainly hire Rene again and will recommend him to my friends and family without a doubt... Thank You Rene!"

"I heard about SES from my friend. He did last year a kitchen remodeling project with them. I wanted to renovate 2 bathrooms, so I called them right away and got 4 more quotes. I felt more comfortable with SES and decided to do the project with them. The result came out greater than I imagined. Thank you guys"

"It was fine. They were trying to sell me a lot of stuff. They could have been right, maybe they were but they have had a lot of costly suggestions.  They were very nice and came when they were supposed to. I have nothing against them more than I was not able to purchase a whole lot of different tads and whatever they wanted to sell me."

Excavating FAQs, answered by experts

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.
