Had an excellent experience with 100% plumbing! After calling around the week of Christmas and not having success finding someone who could clear our kitchen drain quickly, I was happy to find them. They were prompt, professional, courteous and took care of the problem exactly as promised. Will definitely use them again in the future.
Today is our first experience with 100%, they installed a new water heater and 2 bathroom faucets. They are punctual, courteous, professional. Eden did a fabulous job! Do not hesitate to use them for your plumbing needs!
I recently had 100% Plumbing out to take care of some shower valves that needed replace.......the replacement cartridges were difficult to find according to a previous plumber. 100% came out , verified the necessary parts, got them ordered and stayed in contact with me while the parts were ordered......... communication is a rarity in business today but these guys did it very well. They got the parts and the plumber Eddie came out, masked and went right about his business and took care of the replacements. Very impressed from start to finish with this company, thanks for taking care of my plumbing issue........you will be hearing from me in the future on any plumbing issues I have.
Kevin S.The name says it all. Fast, courteous and professional. Had a water pressure reducer installed, the piping was old and constricted and installation by the owners son was meticulous. He explained everything, was very knowledgeable and we couldn't be happier. Definitely recommend
Gerald B.Eddie came out within a day of the call! Looked at three concerns. Unplugged the bathtub and diagnosed a slow leak. Didn't charge because he was able to do it all in a half hour. Polite and thorough.This is my 100% plumber from now on!
Once 100% Plumbing earned my business, they showed me that their top priority was to keep my business going forward. Mont and Eddie went above and beyond to ensure that I was completely satisfied with the purchase and installation of a new toilet. Eddie performed the work neatly and efficiently, and the appointment scheduling was super-convenient too as they even let you know by text message when the service tech is en route. That level of care certainly will have them keeping me as a customer for all of my future plumbing needs.
They were upfront and honest and respected my time and decision. I appreciate someone who explains everything before a price quote is given. This business model empowers the consumer. I will use them again.
Thank you so much for your quick response to my plumbing problem. My technician was Eddie Castillo. He did a good job I was very happy with his service. Thank you 100% plumbing for your quick response. I would highly recommend their services.
5 Stars and TWO Thumbs Up for Jason Ebert and Mont at 100% Plumbing!
My whole house water filtration cartridge was first installed about 10 years ago. But a few weeks ago I began noticing that the housing had started to leak. Luckily, this thing had been located on the outside of our house - so the leak was more of a nuisance than a big mess.
But it was time to replace the copper pipes and shutoff valves, and the old filter housing as well. So I got three prices from three different plumbers. Although the price I got from 100% Plumbing wasn't the lowest, I found 100% Plumbing and the many 5 Star ratings on Yelp from their former customers to be the deciding factor.
Jason showed up on the day and time we had agreed on, and he worked for a couple of hours. When he finished, I found his work to be first class. Everything he said he would do had been done perfectly. All the new copper pipes and shutoff valves were placed exactly as they needed to be. And the new pipes and cartridge housing had no runs, drips, or errors.
I am very happy that I chose 100% Plumbing to do the work I needed to have done. Their price was fair and there were no problems from start to finish. If you need a good, honest plumber I highly recommend these guys!
Brad D.Great service. Very professional. On time and very honest . Highly recommend. Will definitely use them for all my plumbing needs again
