Recommended Customer Reviews

Gene was able to troubleshoot over the phone, saved an emergency situation, and saved us lots of $$$.
On the next job, GS Custom Plumbing will be our first call!

We had an emergency that need to be addressed within 24 hours and they came through. These guys are the best. Great work, fair price and totally reliable.
Can't recommend them highly enough!

Called Gene late in the afternoon and he responded very quickly. Came out the next morning, right on time. Was professional and very courteous and offered me several options for the issues I was having with the plumbing in my house in Sherman Oaks. His prices were very fair and he performed the work very quickly. Can't find a better professional than Gene.

Gene is awesome. Not only does he know what he is doing but is personable and charming. I had an emergency at a rental property and he was there within an hour. He is now my go to guy for anything plumbing related. He should be yours too.

Professional, attentive and performs high quality work. Came out to my house on a weekend (3 times) and honored his original quote. Used high quality long life parts so that I don't have the same problem again.
I would recommend to my Mother.

Gene is the best for sure. Fast, professional, and a great attitude. Knows what he is doing and I would recommend him to anyone. I signed up to yelp just to let people know! I finally have a plumber that I can rely on.
THANK YOU GENE!

Best in the business! Fast. Professional. Reliable. Knowledgeable. I really can't say enough positive things about Gene and his team. Over the past couple years we have used GS for a handful of different services (clogged line, toilet replacements, leaking sink...). Great work! Don't call anyone else.

Gene is the best. I made a panicked call at 6:30pm for a leaking water heater emergency and he was there in 20 minutes.
Gene and Robert had just come off a full day of work and were on their way home when I called. You would never know it was the end of their day, as they were both friendly, professional and energetic... as if I were the first customer of the day, not the last. They did a top notch job repairing the problem and even discovering another problem I hadn't noticed.
I am adding them to my speed dial for any future plumbing needs.

I have to share with other potential customers, how Gene helped save the day! He was responsive to an urgent matter where I could not get any other companies to respond in a timely manner. He was knowledgable, explained the issue and gave options on how to resolve the problem. I felt he was sincere and really trying to help. Gene and his co-worker took the time and saved the day! I will and have already passed on his info to a neighbor for future use!- TG

Based on reviews here, I contacted GS. It took multiple calls and a week or two to get them to come out to look at a job and give me a quote. When I told Gene what was needed, it became quickly clear that he was not the person for the job. He questioned the necessity of the job repeatedly. He was argumentative, very forward, abrasive and rude. I was stunned. Then he wouldn't leave! He basically had to be kicked out of the house. Bottom line - other than his arrogant personality, the setup he recommended was unnecessarily complicated and expensive and the quote he gave was over twice the rate I paid another company - Mainline Plumbing. Mainline came out after one call, completed the job quickly and I've had no problems since. Perhaps Gene is good at unclogging toilets but not ""custom plumbing.""
