"Very efficient and was able to get our water heater replaced in a timely manner. Was on-site on time and replacement done in 2 hours or so. Great crew that did the work. Would definitely recommend."

"I overfilled my garbage disposer!! My sink had 2 inches of water as a result of my trying a plunger to clear it. I called RS Plumbing at 4:45 in the afternoon and Steve came the next morning at 8:00.

He had me clear the area around the basement pipes in case the clog was more major than I hoped. He was able to clear the drain only in the kitchen area. He worked efficiently and had the drain running freely. I asked him to check the dishwasher hosing in case that was part of the blockage. I have had problems with that before.

RS Plumbing was prompt, competent, and overall good to work with."

"He responded to my call and accommodated my plumbing emergency the next day. He was able to fix the problem and clean up his work timely, and stopped the water from leaking.  He was able to replace the outside light fixture by determining that there was a problem that could eventually lead to an electrical fire, identify the resolution, and fix the problem the same day.  He makes sure that the work is done the same day, if possible, and is willing to accommodate your schedule if needed.  He always does great work that is within a reasonable price and timely fashion."

"Theo Matt answered all of my questions and was very knowledgeable about all of my plumbing needs both the immediate ones and the ones that might occur in the future. The service person left me with a bit of a mess to clean up, but I believe he did a good job."
