- BKBob KiolbassaJun 5, 20265.0Personable and efficient.
- CTCarrie ThiergartMar 21, 20265.0Cahill went above and beyond to provide expedited service for a sewer scope and rodding when I was under contract to sell my house. The customer service was excellent, they understood the deadline I was under and really made a huge effort to get out to my house the following morning to get the work done. I appreciate the quick service and follow up communication. They did a great job and I'm happy to support a local family owned business - thank you for your excellent service!
- MMMargaretOFeb 5, 20265.0Our difficult-to-get-to furnace stopped working. The problem was carefully diagnosed and options were offered without pressure, just trustworthy wisdom. The repair was made and then well-tested. We appreciated the good communication, the prompt repair, the honest assessment and careful work. A great company.
- DWDavid WJan 27, 20265.0Very upfront pricing, quick service during a hectic time with -10 degree temperatures, plumbing technician was very skilled and honest. Thanks Cahill!
- SNSusan NewmanJan 21, 20251.0They are VERY difficult to deal with. The billing department is HORRIBLE! I am being falsely accused of not paying my bills, and no matter how many times I; call, text, write letters, they are still saying I am responsible, even though they did not provide the service they are billing me for! Disregard, this response from Cahill! They are IMPOSSIBLE to deal with! The so called "emergency call" was not my unit, and they REFUSE to take my name off of the bill, no MATTER WHAT I DO! I have half a mind to report them to the better business bureau!
