1. Todd Companies, Inc.

Website: https://www.toddcompanies.com/
Address: 7623 N Lavaun Dr, Louviers
Contact: (303) 791-0520 | (303) 658-0384
Hours: Monday – Friday: 8:00 AM – 4:30 PM
Navigating local health department regulations can be a headache, but Todd Companies, Inc. makes the process seamless by handling everything from soil analysis to engineered installations under one roof.
They bring over a century of combined team experience to the table. They operate as both the system designer and the field installer to prevent miscommunication during major projects.
When I was evaluating options for a major property overhaul, a colleague mentioned how helpful their automated pumping reminder system was for staying on top of scheduled maintenance.
You will also appreciate their meticulous record-keeping. They forward all necessary compliance paperwork directly to the state.
However, their standard operating schedule is strictly limited to weekdays. This makes it challenging to book routine services if you work a standard Monday through Friday job.

Extremely satisfied
We are selling our home, and needed a septic line repair quickly! Todd Co was extremely fast and efficient with getting us the repairs we needed, and obtaining the use permit in record time! Extremely satisfied. We’ve used them in the past, and if we weren’t moving, we’d continue to use them.

2. Colorado Pumping

Website: https://www.coloradopumping.com/
Address: 4375 Eaton St
Contact: (303) 278-1884
Hours:
- Monday – Friday: 7:00 AM – 4:00 PM
- Emergency: Available 24/7
Wastewater emergencies require immediate attention, and Colorado Pumping answers the call with rapid same-day and emergency response services.
Since 1975, they have dedicated their advanced technology exclusively to grease trap and septic tank pumping rather than generalized plumbing tasks.
Their inclusive pricing model is also incredibly straightforward, covering complete solid and liquid removal alongside a quick visual inspection.
Even better, they prioritize sustainability by using eco-friendly waste-disposal methods that meet stringent environmental standards.
We like that their service area reaches far into the rural outskirts, where these wastewater systems are most prevalent. Just be prepared to uncover the lids yourself beforehand, as they expect manual digging if there are no ground-level risers.
You must also clear all vehicles from your driveway to give the heavy trucks close access to the tank. This can be inconvenient, especially if parking space is limited or difficult to relocate.
Customer Reviews:

Very good experience
We had an urgent backup of our septic that needed to be resolved ASAP. They were able to make it out the same day to pump our tank. We also had a drain blockage that Bartley was able to give me some advice and a couple of names to follow up with. Very good experience considering the circumstances.

Home repairs often come with pushy sales tactics, but Simply Sewers guarantees its technicians do not work on commission to ensure you receive honest estimates.
They also respect your time by offering a clear four-hour appointment window. To make things even easier, they provide remote FaceTime consultations to assess issues before visiting your home.

Finding a contractor who truly stands behind their work is important, and Sewer Experts delivers with a strong five-year warranty that covers both parts and labor.
They focus on modern CIPP lining technology, which allows them to repair pipes efficiently without tearing up your yard. Plus, their technicians combine rigorous training with 25 years of hands-on utility experience to ensure full compliance with local laws.
We recently spoke with a homeowner who used them. She was thrilled that they strictly avoided pushing unnecessary products during the consultation.
This kind of integrity is something we always look for, whether we’re hiring plumbers or local gutter cleaning companies.
Just note that their base quotes for major line work might not reflect the final price, as required municipal permits and city inspection fees are billed separately.

5. King Rooter & Plumbing

Website: https://kingrooterandplumbing.com/
Address: 100 Fillmore St #500
Contact: (303) 949-2593 | [email protected]
Hours:
- Monday – Sunday: 7:00 AM – 7:00 PM
- 24/7 Emergency Service
Large underground projects demand specialized equipment and expertise, and King Rooter & Plumbing handles them with ease. They can tackle complex excavations, including leach fields up to 200 feet long.
They also handle the stressful parts, such as securing permits and scheduling city inspections, making the process much easier for homeowners.
Before suggesting any major repairs, they use advanced video inspection cameras to locate the exact source of the problem. They also rely on powerful hydro jetting to clear buildup that basic drain snakes cannot handle.
On top of that, their transparent pricing helps you understand costs upfront.
However, standard drain cleaning may not work for severe blockages. Warranty coverage can vary by service, making it harder to know exactly what is covered upfront.
Customer Reviews:
