Guaranteed Plumbing

We were in disaster mode recently on a Sunday afternoon - toilet flooded, yuck all over the bathroom floor and the shower floor in that same room flooded, too. Gross and we did not have the ability to snake the drain, etc. All three toilets and showers could not be used. Early Monday morning I called our valued plumber - Guaranteed Plumbing, Danville, CA. Immediacy was of deep concern and fortunately it appeared this company holds some appointments on Monday for just these types of weekend emergencies. From the sincere receptionist and the scheduler, within three hours, Ben, from Guaranteed Plumbing, met with my husband and helped solve the issue by using a tool that unplugged our main line. What a wonderful relief. My husband requested that I write a review, as Ben was outstanding, friendly and very respectful of our property. He fixed the issue and we were back in business by noon. The household luxuries we take for granted! Fortunately, Guaranteed Plumbing understands how critical it is to solve plumbing issues, such as these, as quickly and efficiently as possible. As a followup to the main line that is full of tree roots, we have scheduled Ben out again to scope using a camera in the line to investigate just how blocked our main line is compromised. Thank you Guaranteed Plumbing.for such courteous and efficient service.

ABSOLUTELY the BEST of the BEST!!! My clients needed a seismic shutoff value installed on their gas meter and I just happened to be driving right behind a Guaranteed Plumbing truck .. So, I had Siri dial their number I spoke to Paul who knew exactly what I needed .. Paul got us on the calendar right away and scheduled Jon for the job .. I didn't know what size the gas meter was but Jon was so prepared that he had all the sizes in his truck including the right one!!! Jon was so professional and extremely knowledgable!!! He clearly explained what he was going to do and how long it was going to take .. After Jon was done with the install, he explained how the red bulb works and how to reset it after a big earthquake .. Then, he relit the water heater and made sure everything was working before he left .. I love AMAZING customer service!!! I'm a luxury real estate agent so I've worked with the best of the best and Jon is definitely the BEST of the BEST!!!

Our half bath toilet next to laundry room overflowed after doing a wash. Called on Sunday, left a message and had a return call first thing on Monday. Plumber came out Monday afternoon and snaked the line to clear the obstruction. Price was very reasonable and Gary did a great job. Also replaced drain lines under kitchen sink which had a small leak.
If and when I need a plumber this is the company I will call.

Best plumbing company I have worked with. They are so professional and really care to do a good job. Johnathan has been to our house multiple times and always goes above and beyond to get job done correctly. Super knowledgeable and gives great advice and shows you exactly what he is doing to fix issues. He also put in new water heater for us. Their office staff is great too.
Use them for sure!!!

GUARANTEED PLUMBERS are ""The best plumbers!BAD=Drain Doctors- Rocky, charged $1000.00 and didn't fix anything :water went down into other part of house. The bad DrainDoctors said we'd need $6500.00 in new piping and would tear out our ceiling and not repair it afterwards and that we needed a new garage disposal.
Well thank God for Guaranteed Plumbing they fixed everything and all the other company was wrong about everything.
GUARANTEED PLUMBERS saved us.
Thank you Guaranteed plumbers!!!

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!

You shower valve in the wall needed replacement and a plumber came out and said he would have to go through the tile to replace it. No way!
Guaranteed Plumbing sent John out and he took apart the handle and replaced the valve and had everything working with an hour. Great price, professional and adept!

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.

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.

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!
