"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.

"I've used All Star Rooter on three occasions and have been very pleased with the work provided. Always professional, punctual and careful, they are specialists. An important indicator of their skill is their position in the industry - three different plumbing companies have recommended All Star Rooter. They will calmly approach a stressful situation and do their best to reach a successful outcome. On this occasion they were able to clear an on-going clog efficiently."

"The team from Gallery of Kitchens & Baths gave our bathroom the upgrade it desperately needed. The Salvatori marble vanity and Pittori cabinetry make it feel brand new and incredibly stylish. The craftsmanship, communication, and professionalism throughout the process were outstanding. Kudos to them!"

"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."
