My kitchen was leaking and I called this people to come and fix the leak. John came to our home and fixed the leak and we were in hurry so I asked them if they can fix it the same day and it was not a problem for them. The price was not that expensive but the job was done week. So far I had really good experience with them . Thank you guys

Same day service, honest and professional. They wear shoe covers upon inspection and whenever entering the house. Tony did a great job clearing up the blockage in our main sewage line. Very thorough and made sure not just the toilets but the shower drain flowed well also.

My mom's kitchen sink was stopped up..after 43 years. Tony from Leo's Plumbing came and did a great job in cleaning out the pipe. Tony cleaned up completely before he left. My mom was so happy..she is 93 and very fussy. I recommend them totally. Thank you!

Leo was fast, friendly, and cost effective. He was able to come out on a Saturday within a couple hours with all the right equipment to clear our mainline. He was done within a half hour, cleaned up everything, and was on his way.

Again and again, Leo has saved me! I have had him help at three properties, including my home - for everything from faucet replacements to sewer back-ups. He is reliable, efficient, knowledgeable and fair. Did I mention friendly? Super easy to deal with, and I always know that when he shows up, my problems are solved. He's definitely the go-to guy!

I had a problem with my kitchen sink the garbage disposal wasn't working, I tried to replace it myself but found out it's just not easy as what I thought, I tried to find somebody online to fix but seems this small job cost quite a little, until I got Leo who came up with a very reasonable quote, he came at exact right time with the right things, get this done professionally, and he even spent some time help me to give my main bathroom a quick fix as well which was not jammed yet but water was running down slow, and Leo only charged me the price of one job. He is a great guy to use without the pressure to worry about big bill if u have plumbing problems here and there, I would like to pin his biz card on my wall and my next possible plumbing job definitely goes to Leo and his folks!

We have a root problem in our main sewer line and my wife just called out another company that charges $88 to try and unblock it. Their ""snake"" equipment was only 100ft long and did not have the proper cutting capability. The drain remained blocked. We called Leo and he showed up on time at 540AM with a 150ft long snake that has a root-destroying cutting bit on it. Leo blasted through the blockage and got our system working again for $120. This time I noticed more about his operation; he has a ten year old van that looks brand new, and he obviously cares well for his equipment. He is polite and punctual. His pricing is $30 more than the cheapest you'll find, but half what Roto Rooter and some others will charge. In short, this is the guy you want to call for drain service in San Mateo and nearby areas.

Guys! Girls! Gentleman! Ladies! No need to look any further...believe me.
First off all, Leo was very nice on the phone and was very punctual. And even nicer when I met him. He was not even going to charge for coming out to look, and he didn't.
Water was leaking downstairs when one took a shower. So I changed the stem units for the two-handle hot and cold faucets on the shower. But water was still leaking. I had used the washers supplied with the units and teflon tape to no avail. Busted pipes? Will I have to tear into the wall? Break the ceramic tiles? Retile?
Then Leo came to the rescue. Found the problem and fixed it within 30 minutes. And after 5 PM on a Friday.
He is very knowledgeable and has a lot of experience and was apparently a manager of a plumbing company for 12 years.
You will not find a plumber that is as fair as he is for the least amount of money.
Saved me a lot of head ache and lots of money. Others might have had me tear down the whole wall.
As I said before, no need to look any further. Don't even bother wasting your time. And don't you worry. Don't have to if you call Leo.
