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.
A leaking or burst water main under the yard or slab is an emergency. Drain Doctor repairs and replaces water service lines for Covina-area homes—locating the break, stopping the loss, and restoring pressure with a lasting fix.
How we help
We isolate the line, locate the failure, and repair or replace the damaged section. When conditions allow, we discuss trenchless options; when open trench is required, we work carefully around landscaping and hardscape and review restoration expectations up front.
