"Extremely satisfied.  Company was responsive (My initial call to them was on Xmas Day when I noticed the sewer backed up in my back yard).  They called me back immediately and  agreed to send someone to look at it the next day (after ansering some questions, we agreed it was not an emergency) - they came the next day as promised and even called prior to their arrival.  The plumber assessed the situation and took pictures to send back to Larry.  I spoke with him and agreed to have them come back on Monday when the equipment  needed to address would be available (needed an extra long hose and camera set up given the location of the cleanout cup).  Each time dealt with the company (Larry) he would call to let me know status and options.  On the day they came, Larry and his associate were at my home at the time promised.  Spent nearly 3 hours and all is well.  So although a bit pricey, well worth it given the responsiveness and professionalism of the company.  Would highly recommend them for any of your plumbing needs.

"Great service! Very responsive, this guy should be the standard with how all sub-contractors work - giving his profession a good name! The price was a bit high BUT given the responsiveness and communication before and after the job, I think you pay for quality. There was ZERO stress working with this plumber. You should do some pluming work just so you can see how awesome it can be. But seriously, timely, respectful, and called/emailed what was going on, good service."

"The professionals completely redone our bathroom. They used high-quality materials without sacrificing style. The matte jade green cabinetry was eco-friendly and gave the space a soothing vibe. The finished product is far more impressive than our original vision!"

"Kyle installed our walk-in shower and did a fantastic job. It was a very long day for him due to an issue with our plumbing, but he remained positive and kept working methodically to complete the job. He was professional and pleasant during his many trips to and from our 3rd floor bathroom. And, we are very happy with the shower. It looks and works great."

FAQs for plumbing projects in Old Greenwich, CT

It depends on the severity of the leak. Minor leaks may not require immediate attention and can be scheduled during regular business hours. However, if the leak is causing significant water damage or you can't control the flow of water, it's best to call an emergency plumber right away. Addressing serious leaks promptly can prevent structural damage and mold growth, potentially saving you money on extensive repairs later.

A journeyperson plumber is a licensed professional with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. They have completed extensive training and amassed significant experience leading teams, drafting blueprints, and designing comprehensive plumbing installations. Their proven expertise ensures that they can handle both routine repairs and complex projects with precision.
