We prefer video inspection before excavation when the line is accessible. Seeing the crack, belly, or collapse on screen keeps repair scoped to the failing section instead of replacing pipe that still has life left.
Localized damage from roots or a single bad joint may qualify for spot repair. Multiple breaks, collapsed sections, or repeated failures on aging clay or cast iron often point to full replacement for decades of reliability.
Bay Area municipalities require permits for many sewer projects. We handle paperwork, inspections, and leave the site broom-clean with sod or hardscape restored to a practical finish.
Every job is completed by licensed plumbers with full liability coverage.
We fix localized damage when possible and replace collapsed lines when repair is not viable.
We explain the problem and quote before work begins — no surprise charges.
You do not need two contractors arguing about scope. We repair when it is sound engineering and replace when it is not.
Some lines qualify for pipe bursting or lining. We explain when trenchless fits Daly City soil and depth conditions versus open cut.
We locate other utilities before dig day and keep you informed if city sewer connection work is required at the tap.
Called ASAP for a faucet leak on a Sunday afternoon. Set up appointment for the next morning and the repair was completed by 9:30am the next day (not an urgent same-day need). Extremely efficient and streamlined experience from the first call to the payment receipt. Great communication throughout. The only thing that I suggest is the receipt be detailed to split into labor cost and materials. My receipt only showed the total cost.

I called ASAP Plumbing Pros for an emergency sewer lateral backup at our house and Don was nice, professional and easy to work with. He was able to get a hold of the senior plumber on call, Z, to be at our house within 20 minutes when the other plumbers in the city estimated a later time at night and others estimated the next day. Z was thorough and seemed to really care about solving our issue with the roots in our pipes. I would 💯 recommend them. Thank you both for making it easy for us.

ASAP Plumbing Pro was called for replacing sewer line during our ongoing driveway and sidewalks project. Donald, Kong and Renato started working as early as 6am, in order not to delay the concrete and pavement. They finished the job before 9am, right before concrete men show up. They are definitely deserved the name of “ASAP”, and highly recommended!

Drain Doctor Don has cleared our sewer line of tree roots twice now, and we will continue to use him in the future until we have the line replaced. Great value and very reliable.

Don came right on time and was very courteous. He wore a mask and brought house booties to wear to keep my floors clean. Don quickly diagnosed the problem. The main sewer line was heavily clogged. He used his 50 foot electric snake to clean out the pipes. He was very clean. I now have a toilet that doesn’t clog and a shower that doesn’t back up. Life is good again, thanks to Don!! I would highly recommend him. He is outstanding!

Don was the man. I called him when my toilets had trouble flushing. Turned out it was a clog in my main sewer line. Scheduled a time with him same day. He showed up on time and quickly got to work. It was a tough clog but he was in and out in about an hour. He cleaned up his mess and installed my toilet back. Very pleasant experience and will definitely reach out if I have future issues. Prices are very reasonable and he was very kind to provide a 30 day warranty as well! Go with Dr. Don!!

Great experience with ASAP. Donald came by for emergency plumbing situation and got it squared away quickly and we ended up asking him to do a few other repairs that we needed!

Kong, the plumber was very friendly and knowledgeable. He changed the sink faucet and carefully replaced the new toilet with no problem. Kudos to Kong. The owner, Donald, was also very friendly over the phone. I also asked him to recommend me a nice and affordable Bidet. Not sure of the price as this was a rental home, so the owner paid for the replacement.

Recurring sewage backups, yard odors, and lush green strips over the sewer path are signs the underground line needs professional attention — not another quick clear. ASAP Plumbing Pros repairs localized damage in Daly City when engineering supports it and replaces collapsed or multiply-failed lines when repair is throwing good money after bad pipe.
We prefer video inspection before excavation when access allows. Seeing the belly, crack, or offset on screen keeps repair focused and helps Daly City homeowners understand why replacement is sometimes the only durable option. Details on our process live on the sewer line repair & replacement hub page.
Bay Area sewer work often requires permits and inspection. We coordinate dig day with utility locates and restore grade so the area is safe to use when we leave.
Pipe bursting and lining can reduce yard disruption on qualifying lines. We explain candidly when open cut is still the right call for depth, soil, or connection conditions in Daly City.
Use the contact form or call (415) 728-6391 for sewer line service in Daly City. Mention backup history and any prior camera reports so we arrive prepared.
Active sewage backups get urgent scheduling. Call to assess severity.
Often yes for localized damage. Camera inspection determines the right scope.

Yes when required by the city or county. Permits are included in our planning.
Recurring backups, gurgling, yard odors, and lush patches over the line path.
