I tried to support a local business but trust me -stay clear of this place. The workers are incompetent. They overcharge you for parts. Not responsive when they try to fix something -they break it just to make money off of you. They came out to fix a minor thing and I ended up with a broken system for over a month! Complaints fall on deaf ears. There are other reputable companies around Danville that may appreciate your dollar better. Check BBB complaints also against this company. Awful service. I will not use them again. read more

Friday at 3pm before a 3 day holiday weekend and the dishwasher starts to leak all over the hardwood floors at my parent's house. The shut off valve is frozen and my mom calls me for help. Called Guaranteed and all their guys are on calls and wrapping up for the day. The receptionist hears the stress in my voice and asks me to hold on. She will contact in of her guys in the field to see if he could come by. I let her know if he could just get the valve to shut off we could schedule an additional appointment for a later time next week for any further repairs. She comes back with great news- Johnny had agreed to come by to help us. Our hero!!!! He arrives within the hour and within 15 minutes the valve is replaced! So grateful for Guaranteed Plumbing. You earned a customer for life. If the repair done haven't been done, my poor parents would have had to continually bail out water all weekend long! read more

We had the best experience with Guaranteed Plumbing. John wore a mask and was very professional. He installed a new water heater and fixed one of our toilets. We highly recommend John!! Kristin and Steve- read more

We are happy with the service. It was good, they were on time and COVID prepared. Johnny is the gentleman who did our service. He was thorough and efficient. They are very busy, but made time to fit us into the schedule. read more

First time using Guaranteed Plumbing. Super fast response and we were able to schedule an appointment at our convenience. They put in a new faucet, fixed a broken pipe under our house and replaced an irrigation pipe bib. Frank and Gary were excellent communicators, funny, fast and very clean! Their price for the work that was done was more than reasonable. Will definitely use again if we need a plumber! Thanks for fixing us up Guaranteed Plumbing! read more

We were doing a partial bathroom remodel and got a referral for Guaranteed Plumbing. Johnny was fantastic. He installed new faucets, a drain cover and reinstalled the toilet after the new floor was finished. He provided great service and was very personable. Will definitely use Guaranteed again and ask for Johnny. read more

From small, service-related projects in our home over the past few years (plugged sink, etc.,) to upgrading the meter capacity for adding gas service to a new kitchen range, an outdoor kitchen and an outdoor fire pit, the team has been extraordinarily responsive. With the larger project, just completed this week, Ryan spent a lot of time analyzing the best methods to accomplish our goals, and priced the work very competitively. Alex and Jay spent all day from the meter to under the house to the outdoor trenches, protecting our home from dust and foot traffic as they worked tirelessly. With the entire family stuck at home due to Covid, they performed with the utmost professionalism and caution. I would highly recommend Guaranteed Plumbing for your projects, small and large. read more

i just love this business. The workers are so nice and patient! ten out of ten for me! i recommend this business to anybody needing a plumber. read more

Guaranteed Plumbing and specifically, Johnny Utz did a fantastic job diagnosing our gas line/fire pit issue. I had called another plumber and a fire pit "fixer" who could not figure out what the problem was. I will be calling Guaranteed Plumbing from now on. Great job! read more

Frustrating experience with this company. I submitted an online request for a quote on Sunday. By Wednesday afternoon, I hadn't heard anything back so I gave them a call. They were polite on the phone and scheduled an appointment for a week out to give me an estimate on my project. About ten minutes before they were to arrive at my home, I got a call that they could no longer make the appointment. This was frustrating as I had made arrangements to be available for the appointment, which was then cancelled with extremely short notice. To make matters worse, they have told me they cannot give me an estimate at all and are not able to take on my project due to my location and a lack of manpower. Both circumstances were known ahead of time yet I got the call minutes before they were to arrive. I understand things happen but after pursuing them multiple times to give them my business, they still ended up letting me down. Who knows how far out my project is now as I have to search for a new company. read more

I was really impressed with Guaranteed Plumbing. Chris came out to my house to give me an estimate. He checked out our pressure regulator, water heater, and our clothes washer (water hammer noise). He explained the scope of work to my husband, who unfortunately has very poor memory. I called Chris, and he was so kind to explain everything to me over the phone. Patrick came out this morning, on time. He replaced our pressure regulator, and explained its operation to me. He also installed a hammer arrestor for my washing machine. It took care of the hammer noise immediately. He discussed the options for my aging water tank. Patrick was efficient, professional, and courteous. read more

First, we called to schedule an appointment for the technician to come out for an estimate. The technician did not show and didn't even bother to call and cancel or reschedule. We decided to give him a second chance and called to reschedule. The service technician came out and spent nearly a hour looking around and spoke with me about options and the potential costs for replacing the pipes. I thought he was informative and honest. He said he would get back to me the following business day regarding the total costs for replacing the pipes. I waited and waited for an entire week and still no word from this guy. I decided to contact him. He responded and said that he would email me the estimates right away. I still haven't received the estimate. I don't know why I even bother to follow-up with him given his responsiveness was poor. I am thankful that I didn't end up using him. If you need someone reliable, this isn't the company to use. read more

I felt I just got the old bait and switch job!!! I needed an earthquake shutoff valve for my gas meter to get the final sign off on the building permit. I asked my contractor to install it but he really didn't have the time or want to do it so he said it would be $525. Seaming like a lot of money I decided to call around and called Guaranteed Plumbing in Danville. I thought it would be nice to support a local company also. They quoted me a price of $400. Not $400 to $600 or it might be more if it's a different size, they said $400!!! Period!!! I booked the job and they came out and installed it. They didn't say, it's a larger size so it will cost more or it's taking more time so it will cost more. They just presented me a bill at the end for $550!!! I told the technician what they said at the office about the price and he said, I'll reduce it to $500. Since then I have tried to get ahold of Marcus Madrid, the owner, to explain what happened but he's never there and I explain it to the office girls. Even my husband has called and explained to the girls in a very nice way what happened. How come no call back Marcus? Just explain to us why we were told it was going to be $400 and you charged us $500. The technician who installed the valve was pleasant and I guess it was installed correctly, who knows for sure, but the bait and switch really upsets me. I hate to do this to a local company but get your act together and please be honest to your customers!! read more

I was selling my dads condo and needed plumbing work done ASAP to close escrow. Ryan gave me a two quotes for work depending on how much I wanted done, from a picture I texted him. He sent a technician the next day and it was completed and I didn't even need to be there. He Emailed the bill after completed. They will always be my Plumbers! Thank you guys!, read more

Had a major clog in my main drain. Called Guaranteed on a Sunday night (non-emergency) and Gary arrived first thing the next morning. He unclogged my main drain then put a larger cutter on his snake to do a thorough clean out of the line. He was able to dislodge two major root balls from the sewer line. I won't name names but the last company that I called was here about a month ago didn't take the extra step to do actually help prevent a recurrence. Gary took the extra step and even told me how to prevent, or at least slow down, future root growth. I would definitely hire this company again. I highly recommend their service. read more

Guaranteed Plumbing has what it takes. Marcus and the team have helped me in so many ways over the last month. Our water heater was old and producing copious amounts of rust into our hot water supply, so after getting referred to them, I gave em a call. They were able to give me a quote pretty quickly, and since It fit with in my price constraint, and their service is 5 stars, I pulled the trigger. Shortly after I had a brand new water heater professionally installed and couldn't be happier. No longer do my whites turn brown when I wash them. Thanks so much guys!!!! read more

My husband & I just renovated our entire backyard and we were referred to a plumber that did not do a good job (esp for the $$), so when we needed some other home plumbing repairs done, I set out to find another plumber. I asked some friends and checked out a couple of websites, once of which was ServiceMagic.com. I received 3 call backs, and Guaranteed Plumbing was the best prospect. They were the only company who didn't charge for an estimate. The owner, Marcus, came out and personally gave me an estimate, which was a couple hundred $ less than other comparable bids I had received in our last project. Their price was very reasonable (you don't want to go too low for this type of service - you'll get what you pay for). Not only was the price right for us, Marcus' service and timeliness were exceptional. He kept to his bid, and even recommended how to plan for our future maintenance. I will definitely be calling on Marcus again for any plumbing needs we have, and if you are looking for a dependable, honest and very knowledgeable plumber - I would highly recommend Guaranteed Plumbing. read more

I called Guaranteed plumbing this past week because I had a leak in my crawlspace. Before calling Guaranteed Plumbing, I tried calling 6 other services: 4 couldn't make it out for a week and 2 never called me back. When I called Guaranteed Plumbing, Gail helped me out right away and she got someone out to the house that day. Chris from Guaranteed Plumbing did a great job. You could tell he takes great pride in his work. But what impressed me the most was that even though it was a tough job and it took much longer than he originally estimated, he stuck to the cost estimate he had given us. I was really impressed. Next time I have a plumbing issue I'll definitely be calling Guaranteed Plumbing. read more

I highly recommend Patrick, as well! As the others have stated, he was prompt, friendly, polite, and explained the problem with our toilet clearly. I even called me after-hours on his cell phone and he answered and came back the next morning to fix another problem.

Vivian S.--- We have used Guaranteed Plumbing several times for our plumbing needs, and they never disappoint. Jonathan and Juliann are truly exceptional and an asset to the group!!, Juliann is the welcoming voice you hear when you call for an appointment. She quickly responds in scheduling appointments, exercises outstanding communication skills, and follows up with updates, always keeping in mind the customer's needs and concerns. She is truly a gem! We were so happy Jonathan was our plumber. He is highly experienced, well trained, and knowledgeable. First, he called ahead to let us know he was en route for our appointment. He arrived with all of the appropriate protocols for dealing with the pandemic. Jonathan can quickly diagnose a problem and offer solutions. He is polite, knowledgeable, and professional . Both Jonathan and Juliann helped us navigate a warranty issue with the company who supplied parts for our faucet and hot water heater and dispenser. Jonathan was invaluable and resourceful in finding a solution to our satisfaction. Lastly, Guaranteed Plumbing is very fair priced. We will never hesitate to call them again for our plumbing needs. read more

These guys are the best. Had a toilet that was constantly running. They came out straight away and completed the repair. The toilet kept running and they came out the same day I called. Replaced all the internal parts again. Excellent customer service. Highly recommend for any type of job. read more

I've got so many calls from the company + an apology from the Luis that i almost developed a 'Stockholm Syndrome'. Ryan called and offered a free inspection on my repair ( it was done and no issues found), Marcus called to make sure that all is taking care of and then Luis called to personally apologize ( thats when my Stockholm Syndrome kicked in). I did not mean to cause any personal troubles to anyone especially during the holidays. GP did not charge me for the initial service although i told Ryan that this was not about $$ and i am totally fine if they do charge, but he insisted. Bottom line - based on the way that company handled my complaint i feel like it was just one minor misstep on their part and not a common practice. read more

I was really impressed with General Plumbing when they came out to diagnose a problem with our well pump. Made the appointment via Yelp, arrived on time, and the service team was polite, knowledgeable, and extremely helpful. I spent some time describing the problem and looking at the equipment with Chris (the technician). He made a thorough diagnosis within an hour and gave me good advice on how to address the problem (speciality electrical and well pump service). I've worked with a lot of plumbers on many different projects and this might have been my best experience ever. Well done GP. Would definitely use them again! read more

Patrick came out and quickly Diagnosed my problem with my plumbing in my house. We had hot water both in the cold and hot water faucets and Patrick was able to quickly identify the issue and correct.

Johnny was our plumber, arrived on time, did an excellent job on all 3 repairs, wore a mask, had a great sense of humor and even laughed at my husband's jokes! Now I feel totally safe from drips and rocky toilets! read more

The results of the work Guaranteed Plumbing performed have not met our expectations. I've been disappointed with the replacement equipment they used. Guaranteed Plumbing disagrees with my assessment. Must be one of the reasons we've never heard back from the main office. I'm considering having it redone on my dime. I personally wound't recommend Guaranteed Plumbing to friends and family. read more

Had some plumbing problems with an older toilet which were beyond my good intentions and lame skills. Guaranteed Plumbing responded quickly. Our plumber, Gary Sanchez, was very pleasant, courteous and efficient. He wore a mask and was careful to maintain social distancing protocols. Beyond the repairs, he made some suggestions without any kind of a "hard sell". We wouldn't hesitate to use Gary and Guaranteed Plumbing in the future. read more
