Customer reviews
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.<br><br>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!!

Came home to no hot water. Asked neighbors who to call. ASAP was true to their name. Showed up almost immediately, diagnosed the failed hot water tank, and got a replacement installed very fast. Also fixed a flow issue we had.<br><br>Good communication throughout the process, which I greatly appreciate.

Super quick response, able to fix all the issues they saw at a reasonable price after hours for emergency faucet and pipe replacement. Gave me constant updates and provided photo evidence for all issues they saw and recommended preemptive fixes that would’ve caused issues in the future. Super professional and was able to fix all issues in two hours.

I tried to fix the clog myself but soon realized it was a job for a professional. Kong quickly assessed the situation, took some photos and chatted with supervision. In no time the problem was diagnosed. Clogged sewer pipe instead of clogged shower drain. The price list was easy to understand, and no surprises. It was tough one, but Kong tackled the problem and left my bathroom nice and clean. Great job and thanks.

ASAP plumbing hydro jetted a plumbing line that frequently got clogged. In the past, my usual plumber would snake the line, but I think that wasn't enough to fully clean out the pipe. I'm glad I had to call ASAP plumbing for after hours service since they offer hydro jetting. They are more expensive than my usual plumber and you have to pay extra for after hours service, but they came at 7:30 pm (30 minutes after I called) and got the job done!
