I must say Derrall is a very good plumber; he is not the cheapest but reasonable for the quality of work he does. He gives the best solution to a problem. And he can work in many areas. The latest project I had for him was redesign my dryer vent as the duct was cracked at the opening near the outlet. He made sure the pipes slope in the right incline to ensure the flapper is open when air flows out and remain close otherwise so pests would be kept out. I got most of the parts ready for the project and he was able to make use of them to the fullest even though not all was ideal: e. g. no elbows, need straps to secure pipe to wood and a 4 ft vent duct instead of the standard 8 ft that would be stronger. He was able to grime the pipe edges for better connections with his tool. We saw very good air flow after all was finished. read more

FINALLY! We have found a plumber we can trust and who responds in the most professional manner! Derral Yee responded to our desperate plea for help immediately after we detected a SECOND leak in our home. He carefully explained that due to the age of our home and the poor quality of our copper pipes, a repipe would eliminate the worry of future probable leaks. Derral also gave us a cost estimate for a repipe and explained the leaky pipes could be repaired at a much lower price. Not wanting to deal with the doom of another impending leak, we chose to repipe using a combination of PEX and high-quality copper pipes. Derral's team showed up on time and the repiping was completed in LESS than SIX HOURS! This time frame included repairing all holes in walls and clean up! It is amazing how we take running tap water for granted, but we will never take Derral Yee and his team for granted. Derral was the utmost professional who was in constant contact with us by keeping us informed about scheduling. He always sent us his projected ETA, and he always showed up on time. His projected estimate was exactly what he said it would be to the penny. He required a 10% deposit and payment in full upon completion and satisfaction of the project. We highly recommend GK Plumbing! Derral Yee is definitely our go to plumber from now on! read more

I smelled gas under the stove top. D was available the next morning. He came in and assessed all the gas pipes under the house and let me know what was and wasn't up to code. It was very helpful. He explained the way the pipes should be connected. I appreciated this rather than just talk in layman terms. He let me know what needed to be fixed now rather than some workers that make you believe you need to fix it all right away. I appreciated his honesty and professional manner. read more

Derral is just the greatest plumber ever. He comes out when he says he would, and he seems to be able to figure out the problem and fix it right away. I do have a Home Protection Plan, and I always have to fight to get him. It's a battle well worth it. He was at my house today to replace two leaking faucets. Everything is perfect, and the faucets are name brand. I'm really happy with the work he performed. Don't hesitate to call him. He really is the best. read more

Wow!!! I've never had such a great maintenance or repair visit on my property! Darrell was amazing, he showed up even though it was super late but didn't charge us a crazy bill because of the time and urgency. He was super professional, nice, explained everything to us, and our options. I'll never call a different plumber again! read more

We called Darryl this morning and he called back immediately. He came out that morning within 20 minutes and looked at our problem. He quoted us a price and came back within an hour with the correct tools and fixed our gas leakage from a shutoff value. He quoted us one price and fixed the entire issue and helped us with another issue for free. We are so glad that we found a plumber we can trust in the Monterey Park area. My sister already has plans for him to fix her water pressure issue, etc. read more

I had a clogged mainline and I called GK Plumbing and spoke with Derral. He explain what the issue could be and gave me a estimate and then he took out his camera and identified the clogg and started to snake the mainline and removed the tree roots. Derral was professional and stand up guy and I will recommend anyone for his services. Thank you GK Plumbing for a seamless job that could had been a nightmare if I choose one of those other chain company. read more

My wife and I have used Derral Yee's plumbing services on several occasions:  first to fix our water heater, and then to replace a leaky faucet, repair a clogged sink, and install a new toilet.  We were quickly impressed with Derral's technical expertise, practical knowledge, and deep experience.  We enjoy working with him:  he's a true professional at his trade, and a very personable human being as well.  My wife and I are happy with the work that he has done, and feel fortunate to have found him. read more

This is an excellent company! Mr. Yee came to my house to fix my hot water heater. He came as late as 10:30 at night and even came back on a Sunday! He was friendly and professional. He not only ordered parts for my water heater but he also ordered a camping hot water shower to hold me off during the week I had no hot water. He really is amazing. Thank you for helping me out in my time of need! read more

Derral Yee is the professional plumber everyone needs. He was recommended by my realtor when I was selling my brother's condo and it needed quite a bit of work done. He was thorough, professional and did a great, complete job. He even asked if he could follow up just to make sure everything was in working order. That is truly uncommon and very much appreciated. I was so impressed with his work and attitude that he has now become my plumber and have been happy with the work he's also done at my home. And another big plus: he is very aware of time, both yours and his. He was on time! read more

Tired of plumbers who arrive late and aren't clean? This man's work is immaculate. Prompt, clean, professional, there's nothing really bad I can say about his services. Not only did he fix the issue with my water heater leaking, but he helped identify other issues I didn't even know about. He's honestly trying to help so that no other issues arise in the future. Highly recommended. I didn't know much about the issue and he answered all my questions. Super knowledgeable. Customer service top notch. read more
