Reviews of local pros in Alsip, Illinois

Very professional team from start to finish. Had a couple of jobs for them and they had them scheduled and completed in just a few days. Great company to do business with.

Alan is always professional and informative. Never have a problem with any inspections or repairs he has done.

CBI has been taking care of our buildings back flow system for 15 years+ and are always on top of things with no problems through out the years.

Great company. They handle all of our rpz testing. Always on time and get it done right. Office staff amazing. Would highly recommend for all of your backflow valves.

JJ was absolutely fantastic to work with. He was very knowledgeable and friendly, and explained what he was doing and made it simple for me to understand. Thank you JJ, see you next year!

I got quoted $240 then I got quoted $99 for the work and then I ended up getting charged $240. While the technician that came out was pleasant to work with, their back end office is a mess. They need to get their act right.

They're quick concise and affordable. They were in and out and knowledgeable, We will use them at all of our properties.

Mike Gleeson is the man

Went above and beyond

And represents absolute class and professionalism in his expertise

Call these guys and gals for anything back flow related

CBI came on a moments notice and provided excellent service. Eddie was excellent! Very informative and helpful. Completed in a timely manner. Very grateful.

Backflow testing cost twice as much as last year.... total misunderstanding. Customer service rep did not explain pricing. Talked to someone else and they explained what was going on. I have a lot of devices and I need to have them check annually so this is the best company to do it. I should have asked more questions.

I wanted to take a moment to acknowledge the excellent work done by Matthew Krolak. His professionalism and attention to detail were truly commendable. Thank you for having such dedicated team members.

Chicago Backflow was very professional from the office staff to the onsite technician. The office staff provided a time-window and Genaro, the technician called early and showed up on-time.
As a plumbing novice, I do not have much experience with backflows or plumbing. I highly encourage to opt for their $150 test/repair package instead of the standard $99 for first-time customers. It is slightly extra but if the backflow test were to fail, you might be quoted the standard price that will be substantially more.

I love this: The office makes an appointment, with an actual time range. Then the service provider calls to say they are on the way, during that time. And then texts you when they arrive. I made an appointment for our next annual backflow check - in 12 months!

Top notch service!!! We are a new to the area company that needed a portable RPZ to use on city of Chicago hydrants, the owner himself took the time to sit down with us and write down exactly what to get and where to get it. They also set up a prompt test date for it. Thanks again!

Have been using CBI for years…the same team member, Mark, comes every year. He is courteous, prompt, respectful and no mess after completion. They will continue to be my go-to!

We have been using Chicago Backflow from 2014-2022.
I call them every year to schedule our backflow test. They are very professional, certified and knowledgeable. Their prices are very fair and our company will continue to use them. I give them 5 stars!

CBI has been servicing my home for four years with our sprinkler system. They are the best. Always on time, great service and low prices.

Thank you CBI,

We used CBI for our backflow inspections. They were extremely responsive and quick to give us pricing. The technician, Mark, was on time, professional, quick, efficient and able to answer many question I had about our specific devices. Couldn't have asked for a better experience. CBI had much better pricing than other companies in the area who we've used in the past. 5/5.

Genaro, the Tech was professional and pleasant to work with (second time). He took the time to explain what he was inspecting and why it needs to be inspected. Had a question on my sump pump he gave advice on. Can't go wrong with CBI for your annual backflow inspection.

We had a sudden issue with at our business with one of our pieces of equipment during operating hours. I called CBI and they were able to accommodate us with a technician in a very timely fashion. It was necessary for the water to be shut down for the entire facility. The CBI technician diagnosed and had the water back on within an hour. We thank the CBI team for having such a professional and caring work ethic.

Still the best backflow testing and certification we've experienced. Chicago Backflow is our go to company for backflow device testing. As always, Jack came on time and was very professional. From the first contact to schedule the appointment to the payment process, everything was handled by courteous, knowledgeable staff. We highly recommend Chicago Backflow and look forward to hiring them again in the future. We wish them continued growth and success in their business!

Add-on:
I forgot to give a special mention in my original post to Valerie. She was the one who answered my service call. She was a pleasure to talk to and very attentive to my scheduling needs. She is certainly an asset to the company.
