What you get from Drain Doctor:
Call for Conditions & Restrictions. *Some restrictions or conditions may apply, call for details. Offer may be subject to credit approval. Must present offer at time of service. Not available to combine with other offers/promotions.
Rooter service clears stubborn main-line and sewer clogs that a simple fixture snake cannot reach. Drain Doctor runs professional rooter equipment for Covina and San Gabriel Valley homes when grease, debris, or roots are restricting the line.
How we help
We access the main cleanout when available, feed the cable to the blockage, and clear the restriction. If roots or recurring backups suggest a damaged lateral, we recommend a camera inspection so you can see whether clearing alone is enough or whether sewer repair is the lasting fix.
Local experts
