Had a rusty water regulator. Called KP plumbing. He not only replaced the regulator, but also installed a 1/4 turn shut off valve. Great job!

Kevin is fantastic ! He is as good as they can come, perhaps, better than the best out there.

After getting a runaround with a couple other local plumbers, I was hoping that Kevin would be ""the one""; I'm so glad he was !

We were having our kitchen remodeled and needed someone to do the plumbing after the countertop guys got done with their part. Our schedule was tight and needed to have someone come in on a Sunday, right after the guys got done to set up plumbing and install the new dishwasher for us.

The communication with Kevin was outstanding from the onset. There was no beating around the bush, no frivolous talk and most importantly, no bait and switch. I sent him pictures of what the kitchen looked like at that moment, and he quoted me a max price for his work.

The price was more than reasonable and with Kevin being local, it was a no brainer.

From this point on, it was only a matter of communicating how the previous work was going and setting expectations with him of any possible delays on our side that might affect him. This was the part that impressed me the most. He was thorough in his follow-ups and let me know what I would need to procure before he got there, so that he did not hit any snags.

Kevin showed up on time, was immaculate in his craftsmanship and got everything done on schedule. His pipe setup looks like an artwork and it's a shame that it's under the kitchen sink where very few people will be able to see it. He left us more than satisfied with the quality of his work.

Overall, being the sole person doing everything; the scheduling, communication and work, I was impressed by how efficiently Kevin runs his business, his honesty and the quality of his work.

I wish him all the best for his business. We will have absolutely no hesitation in using his services in the future, although we wish to never have the need to see him again ( no offense Kevin ! ).

I have lived in my house for over 8 years and have been looking for a good plumber every since I moved in. I have been through at least 6 to 7 plumbers and either they are too costly or have only done an average job at best. I have FINALLY found my plumber. Kevin was honest, inexpensive and did a tremendous job.

I previously called a larger plumbling company for an estimate, and they were going to charge me over $7,000. Kevin was going to do the exact same job for over $3,000. After examing the problem, he found a $200 short cut that would at least band aid the problem for 6-12 months while I saved up for the $3,000. I appreciate his honesty, hard work, and just overall professionalism. If you want an excellent plumbler, then I highly recommend Kevin Hoffert.

Again, after 8 years of struggling to find an honest, hardworking and professional plumber, I have finally found mine.

We had 3 separate slab leaks in different parts of our house over several months last year. Kevin came each time and fixed them promptly. I was quite pleased with his work and his professionalism. He is easy to talk to and very willing to explain what he is doing and why. After the third leak he told us it would be best to repipe. He explained what it was and how it would be done so i would know what to expect. He gathered his workers together and the job was exactly like he said. There were no surprises. He did great work. I really like this guy....his prices are reasonable, he doesn't try to talk me into anything i don't want but he will explain why something is necessary, he is willing to come out at odd hours, and he is just a nice guy. I will happily recommend him to anyone.

Had an emergency situation at my house this morning, after shutting off the water i called several different company's. KP plumbing was the only company willing to come out and help me with my issue, kevin arrived within an hour and was professional, explained what the job entailed and gave me multiple options. He didn't try and upsell me on any unnecessary work and was very reasonably priced. He also noticed one of my hose bibs was leaking and replaced it free of charge. Thank you Kevin for the great service!! If any of my friends or family run into any plumbing problems I'll be sure to let them know of KP plumbing.

I would HIGHLY recommend KP Plumbing. Kevin has done work for me at my rentals several times. He goes above and beyond to work around my schedule. Because it is my rental, I am not there on the property. Kevin is VERY communicative on his progressof any job I have sent him to do. He has always contacted me to let me know what the issue is and asks me if I want him to continue on the job. He is very professional and knowledgeable. What I especially appreciated about him is that if you text or call, he gets back to you almost immediately! In this day and age, that is worth its price in gold!!!!!
