These guys are AMAZING!!! I've had to call them twice in emergency situations and both times were at my door in an hour. Miguel came to fix a toilet leak on New Year's Eve at 5pm. Wasn't able to fix it, and showed up this morning, (New Year's day!) with a brand new toilet! Alex came to fix a broken pipe and while he was here replaced a piece on my toilet for me and fixed a leak on my garbage disposal as well. Gary and his crew are extremely professional, know what they're doing and are very reasonably priced! I'm so grateful for these guys!!!

Gary Costello answered when I called yesterday evening for a clogged kitchen sink , gave me an appointment for early next day 9-11am, he arrived wearing a mask & shoe coverings, which was appreciated. He brought his snake machine through backyard to the clean out & ran it 50 ft, 2 x said the clog was at 35 ft. Explained everything , charged $225 less 10% for a total of $202, (the most I've ever paid for this) , he also shared recommendations to help keep pipes clean longer , a biodegradable substance which I immediately ordered on Amazon, he hosed down & cleaned area. Work has

We hired Costellos for a plumbing job. We contacted Gary for an initial assessment. It was Miguel who showed up the next day for an inspection. He was very knowledgeable and didn't even charge for his visit. After speaking with few other plumbing companies , we fet to go ahead with Costellos as Miguel made an impression on us in terms of knowledge and honesty. We specifically asked for Miguel, Gary was very accommodating and sent him on his earliest availability. Miguel did a great job fixing our problem . He was very polite, efficient and seemed to know what he was doing. They cleaned up

I've used Costello 4 times now, (Snaking drains, fixing toilet, replacing gas valve for new oven). They communicate very well and will text for appointments (wish I love!) They are reliable, kind and know what they are doing. Their pricing is very fair and competitive with pricing in SF and will give you a fair estimate on the project ahead of time!

Thank you Costello Plumbing for being so responsive. I needed the backyard hose valve replaced and you came the next day. The plumber, Miguel, was professional and explained everything he was doing along the way. The repair took less than 45 minutes which was great.
