We received first class customer service from the first call as a new customer to book a plumbing repair, to completion of the job. Our plumber arrived on time, assessed the work to be done, gave us a price, and finished the job. He was friendly and helpful throughout. We're happy to have an established, reliable, family run business like this to turn to for our household maintenance and repair needs.

“I’ve called Alex Munoz at Onestop Pro Plumbing twice in the past week.”
I’ve called Alex Munoz at Onestop Pro Plumbing twice in the past week. Once for a kitchen sink & drain issue and again today for a sump pump problem. He is a trustworthy man and, even though plumbing issues are not cheap, the last thing you need is a plumbing scam artist. Alex is the opposite of that; he is an up front professional.

Alex helped us fix a leaky shower head that turned into a much bigger project than we anticipated (due to some old plumbing)! He was great at communicating the scope of the project, helping us navigate some tricky behind the wall repairs (without taking apart our shower), providing a fair estimate, and cleaning up after the project was complete. We are happy with his work!

“Had Alex come out mainly to install a garbage disposal.”
Had Alex come out mainly to install a garbage disposal. Did a fantastic job with the install being thorough in all he did. Hooked up a dryer vent in my crawlspace as well. Offered some suggestions on the venting and with everything repeatedly offered to come back out if any problems. I feel very secure in all he’s done. Extremely satisfied with all he did. A very efficient and hard worker. Great guy!

Great company. Come same day. Good tech to follow process and pay. Nice and experienced professionals. Most importantly if you have an issue after a service, they have your back. No nickel and dining. Unless of course it’s a totally different issue. . I called and had an issue that was maybe related to the service. Arguably not. On a freezing high demand day. They figured out how to get someone to come out same day. Even waited for me when I was late coming home. No extra charges. Fixed problem. Great customer service! Wins every time

“Needed water heater replacement and they were able to come within a couple days.”
Needed water heater replacement and they were able to come within a couple days. Showed up when they said they would and did the job in a very timely manner. Jeromy was courteous and helpful answering my questions. Would def use them again!

“Fast, transparent, kind, professionals with straightforward pricing.”
Fast, transparent, kind, professionals with straightforward pricing. I found OneStop online when I was looking for a local plumber. I spoke to a real, local employee. She quickly scheduled an appointment for me, fitting me during the busy holidays, and the plumber was fast, straightforward with the cost estimate, and did the work well. Could not be more impressed. They will be my new go-to repair service for plumbing and HVAC. I’ve used other prominent DuPage County companies in the past but they either overcharge me, are too busy, can’t make their appointments, or do quick and dirty work.
