Plumber in Lake Forest, IL
Offering Decades of Plumbing Experience Satisfying Customers
30 years ago, the founder of Little Tommy’s Plumbing Shop, Tom Mahoney, started his first plumber’s apprenticeship with his father, Bart Mahoney, Jr. Bart had already been working in the plumbing industry since 1947 by that point, and was able to pass a wealth of knowledge down to Tom which still informs our business today.
However, beyond all the tips and tricks, beyond all the trade secrets Bart imparted to Tom, the most important thing he passed down was a commitment to the customers. That’s why our Lake Forest plumbers believe that the foundation of a great business is long-lasting relationships built on trust and respect. We have warranties available.

“It was a pleasure to meet Jordan. He arrived in time. He is friendly, polite and respectful. He solved my problem quickly and explained my options to me. I highly recommend Jordan and Little Tommy's.”- Deena F.
-
“Always happy with my interactions with Little Tommy's. Highly, highly recommended. One time when my sump pump backup failed, Tommy was able to face-time me on a Sunday to help diagnose the problem. Last week when my Water Heater was leaking, Tommy was able to come out in 30 mins to quote me a replacement and we were back up and running within the next day. Again, they are highly recommended, and would use again!”- Dustin G.
-
“There is a lot to be said about supporting local folks. And over and above that fact Little Tommy's was OUTSTANDING in all aspects of our encounter. From the friendly young lady on the phone, to the quick response, to Jordan the total professional who accomplished the installation. The price was fair and there was a no nonsense quote. I feel totally confident in recommending Little Tommy's.”- Mike L.
-
“Jordan did a great job. Our cast iron pipe going out from our house to the sewer line had broken. We had a backup of the sewage water inside our bathroom on the first floor and the basement. Little Tommy’s Plumbing company fixed the issue by removing the part of the cast iron pipe that was broken. It was about 4 feet under the ground and installed a PVC pipe. They also obtained the village permit for this work on an expedited basis. Great company. Reasonable price. Would highly recommend for plumbing repairs.”- Sudhir P.
-
“Little Tommy's sent Josh to fix my sink. Delightful experience and result. Josh fixed the problem immediately and then imparted very useful advice and pointers to avert plumbing issues. Best company around here.”- Steve O.
-
“Tom from Little Tommy's provided me a thorough and timely quote as I am selling my house. The best thing is that he partnered with a tile and a glass company to provide a comprehensive quote. Great customer service and follow through. I would definitely recommend his service.”- Michael W.
-
“Tyler did a fantastic job! It is such a pleasure to do business with a company who is efficient, fast in an emergency, and is trustworthy. I was left feeling they were completely fair and their service exceeded my expectations!”- Linda S.
-
“They correctly diagnosed and repaired our issue after the first plumber ghosted us and the flooding began again.”- Craig N.
-
“Tom came to my house right away to provide a quote on a somewhat complex basement project. The quote was fair and prompt. The crew was at my house over the course of 3 consecutive days to complete the project, and I could not be happier. Not only did they do a great job (on a not-so-straightforward project), but they were flexible, polite, and patient in working with me to get it done correctly. As a homeowner, it's comforting to have contractors who are willing to explain what they are doing, and they were patient with my naive questions. I would recommend them to anyone and, without question, will be using them for my plumbing needs going forward.”- Tony C.
