Sewer Cleaning

We offer two types of sewer cleaning services:

Emergency sewer cleaning: Has you sewer line backed up? If you are dealing with a back up, we can get out to you today so you can get back to using your water and toilets again. We offer a four hour emergency window to get out to you fast and solve your problem.

Preventative Maintenance sewer cleaning: Dealing with root growth in your sewer line? There often isn’t a need to spend thousands of dollars on a sewer line repair when you can maintain the line instead! Preventative maintenance clients save money by having us out before there is an emergency.

  • A bathtub drain full of hair

The curse of the clogged sewer lineSewer Camera Inspection

Our sewer camera inspection allows customers to see the condition of their sewer line. This is ideal for:

  • Repeat backups – determining the cause
  • Real Estate transactions – see what’s happening before you buy
  • Determining if there is a break

Free Second Look

If a competitor has given you a sewer camera video, we will watch it for free to offer you a second opinion on a solution for your sewer repair. We’ve done this as a service to the community for as long as there have been sewer scopes performed because we have seen first-hand the lack of ethics in this industry. Please read our blog on red flags of sewer scope if you are feeling uncomfortable with the sewer scope you have received.

Sewer Line Location Services

Sewer line location services allow customers to know where their sewer line is located within their yard or property. This is ideal for those:

  • Digging up the sewer line
  • Digging up the yard or property for renovation or landscaping projects
  • Wanting to install an outside riser / outside cleanout


Our standard machinery is the Roto-Rooter(r) machine, however, in the case of heavy grease, dirt, or sand, the Jetter is the better equipment for the job.

Using high pressure water, our truck mounted Jetter blasts through commercial lines to clear them of the most stubborn clogs.
