Recommended Customer Reviews

First plumber that looked at the issue said fix was going to be a lot of work and expensive. Kosta Plumbing finished the job in minutes!

The team at Kosta Plumbing are fantastic. I had a water heater issue and Kosta Plumbing expedited service to help me over the weekend. George came out to my home the same day and diagnosed the issue. Had a new water heater installed immediately. Very knowledgeable, professional and followed up with me to make sure everything is working properly. Make sure you request Kosta Plumbing for all of your plumbing needs.

Kosta was assigned as part of my home warranty service. He was very responsive to MY calls and as soon as he was provided approval by the warranty company, I got a new water heater within less than 24 hours. He was very professional and courteous. He left my home better than he found it.

George is amazing! He was the assigned plumber from our home warranty and we were so lucky to have him. George is very knowledgeable, honest, prompt and reliable. Highly recommend Kosta Plumbing!

So my homeowner's insurance uses this company to do repairs.
I had my water heater break down and had to get a replacement.
The company charged me for earthquake straps which I had said at the time I already have them on my other water heater. Why did I need new ones?
I was told that I needed new ones fine.
He installed the old ones stating that he did not know whether or not we were actually charged for them, which indeed if he would have looked at the check I left him it showed for the plumbing parts, the cost and for the earthquake straps.
The man said he would go ahead and talk to the office about this. However, he immediately went to my bank and cashed the check that same day. I have called several times and I get:. Oh yeah we sent a check out. Oh let me check if the check went out. We send the checks out the first in the 15th. Yeah I got the run around. Thanks but no thanks. Won't be recommending them anytime in the future

This is our second experience with George at two different homes dealing with old water pressure valves and water heaters. George is professional and most importantly honest. Many other plumbers won't quote you time and materials and instead just make up some astronomical price for something that may only take 10 minutes. Don't hesitate to use Kosta.

We were assigned to Kosta Plumbing through First American Home Warranty after a negative experience with another plumber. Kosta Plumbing was great! George was knowledgeable and did a wonderful job repairing the leak in our kitchen sink. He installed a cleanout, which was NOT covered by our home warranty and offered us a very reasonable price. I would highly recommend Kosta Plumbing and would not hesitate to call them for any future plumbing issues.

Great and timely work. Would contract again. George was responsive and offered helpful solutions to plumbing issues

Be very careful with these people! George worked on a leak that we have. After 2 weeks we started having the same issue. I called and left a couple of VMs but never heard back. Basically he failed to fix the problem, charged us and never got back to us. Very frustrating and unprofessional.

George saved me today in an emergency call. The pilot lights were accidentally turned off on my main water heater so I suddenly had no more hot water. Apparently, that happened when I had some workers over that were capping the propane gas lines in the attic in the changeout from propane to electric heater and ac. George saved the day and replaced the pilot light assembly. His price was extremely fair. I was so relieved he fixed the water heater so quickly I even hugged him. It's very hard to find an honest plumber in San Diego. Thank you so much George, you are the best !! See you soon for my next plumbing projects
