What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
Aggressive billing and collection practices: Two nearly identical 1-star reviews document unprofessional conduct during payment disputes—one reviewer reports a manager named Bill threatening a lien over a $270 second charge and 'immediately aggressive' behavior, with a prior office acknowledgment (Fred) that the charge would be waived.
Cited in 2 of the 193 reviews we analyzed.
Red flag
Inconsistent accountability: One 2-star Yelp review states technician created a problem (burst pipe during repair), company failed to verify solution before leaving, and reviewer was blamed for not double-checking.
Cited in 1 of the 193 reviews we analyzed.
Opaque pricing on complex jobs: One reviewer noted final bill ($636) nearly doubled the $400 estimate, and another experienced unexpected $270 second-bill after initial sump pump quote of $950.
Cited in 2 of the 193 reviews we analyzed.
Office communication gaps on service details: One 4-star review explicitly cited 'office staff interactions weren't pleasant or proactive' and lacked clarity on warranty registration and upfront pricing breakdowns.
Quality control on first visits: One reviewer reported technician arrived without correct 2"-to-1.25" fitting, attempted reuse of old part, caused sump pump leak, requiring a costly return visit.

The evidence — in reviewers' own words
Critical
“We would not recommend Green Tech. They are very over priced for the overall work they did and while they fixed the problem, they created another problem. We will take blame for not checking this ourselves before they left. We let the service tech check things when it was our house and money. Suggestion for people needing a Plummer : 1) Get a quote first. 2) confirm/test that the solution was fixed at …”
“Bait and Switch on Quoted Price and Unfair Billing Practices I hired this company based on the numerous positive reviews I had read, and was initially quoted $950 for a sump pump replacement. The initial service appointment immediately ran into a complication: * The technician did not have the necessary 2" to 1 1/4" pipe fitting/reducer for the job. * He attempted to reuse my old fitting. * After assembly, the sump …”
Positive
“I was extremely impressed with my recent first-time experience using Green Tech Plumbing. I worked separately with Bill, Jarrod, Declan, and Tim, all of whom were punctual, friendly, and provided honest feedback and did a great job. As a female home owner, I often dread home repairs that require a technician since I am frequently met with exaggerated estimates along with aggressive attempts to upsell maintenance …”
“Green Tech service is excellent. Their tech was very polite and quite knowledgeable. He gave me regular updates as some repairs took some additional work and took some time. But the work was completed to my complete satisfaction. Also their rates are reasonable too. Great service at a great price! I would highly recommend Green Tech for any plumbing work in the Chicago area.”

Across platforms
Google 4.8/5 (349 reviews) vs. Yelp 4.6/5 (100 reviews) show minor divergence. However, the two most recent 1-star reviews on both platforms (Nov 2025) describing identical 'bait-and-switch' billing scenarios suggest emerging pattern not yet reflected in older high-volume Google ratings, indicating platform data lag on developing reputation issues.
