Had a leakage with shower head and found them on Thumbtack. They came out same day and fixed it the same day too! Explained the issue very well and offered multiple options for repair. Highly recommend

Leak Detection & Repair services reviews near Pacifica
We had two leaky sinks in our house and called ASAP to fix the problem. Kong arrived and quickly assessed the situation. After discussion with both Kong and Donald, we concluded that the repair for the basement sink would not be necessary. Kong fixed the kitchen sink in a timely and professional manner. I would highly recommend ASAP for your plumbing needs. They provide fast, professional service at very reasonable rates. I also like how they provide a one year service warranty.

Quick and responsible service. Don checked and repaired our leaky sink and water faucet adapter the same day that I called for the service. The work was professionally performed with proper cleanup afterward. I also like the fact that he wore shoe covers inside the house without the need for me to ask him to do so. Great work!

Don has done work on our home two times; fixing leaks in two bathrooms in our home. He quickly assessed the situation, provided details and options for addressing the leaks. He repaired the leaks quickly due to having the parts available in his truck (no need to run to get parts). We also just like Don - he's friendly, professional and shoots straight. Thanks, Don!

Don was able to come out next day to fix a leak. He was super quick to diagnose the issue, recommend a repair, and follow through with it right away. Pricing is a great value, and we’ll definitely use his business again!

Don came over to fix a leak under our sink within 3 hours of reaching out to him. He was able to make a repair on our disposal rather than replacing the whole thing to keep the costs down. He was very friendly and helpful. Would be happy to use his services again in the future!

I’ve used Drain Dr Don a few times for various plumbing needs: clearing blockages, repairing leaks. They are very responsive, no BS, professional, properly priced. I highly recommend their services when you have a plumbing emergency.

Donald was communicative about scheduling after a big rain (when I’m sure he was swamped), and was great about getting in, diagnosing the source of the leak (backup in a section of pipe), providing an estimate l, and finally repair it. Would definitely use him again for plumbing work!
