Jim from JMB was wonderful to work with during our renovation which included a new water supply and drain for a new kitchen sink and dishwasher installation. He was considerate of our condensed timeframe and diligent about getting the work done in coordination with our other trades. Already asking him about some repairs we need in the same house as he was great to work with.
Jim was extremely professional and courteous. He got the job done efficiently and at a very fair rate. He was very neat and an extremely nice guy. Highly recommended. Thank you Jim. David Nero
Nice work and more importantly where able to work in a price that was reasonable I will definitely keep them in mind for future work and tell friends about them.
During cleanup after a water tank leak, our disaster mitigation crew referred JMB Plumbing to repair a corroded water line to our washing machine. Jim not only took the time to go over what needed to be done to get the washer up and running again, but suggested moving the appliances to a better location in the basement, freeing up the space for the pool table my husband's been dreaming of. He came back in a day or two and was able to complete all the necessary plumbing, replacing and re-routing the old flimsy dryer vent, removing old water lines and old laundry sink, and moving both washer and dryer to their new location, all at a very reasonable price - and completed in a span of about six hours. He even included a faucet leak repair and a drain popup fix in the total price. Jim was friendly, polite, professional and an expert in his field. We'll be welcoming him back in the near future to re-install the toilet and sink in the restoration process.
Jim installed a tankless combination boiler/hot water heater on October 30, 2023; he committed to a follow up service call after 12 months, I have been trying to reach Jim since last Oct and he has not returned my calls, now the system needs cleaning and a fix for the hot water supply temp which keeps fluctuating in temp.
