Customer Testimonials

We did a major renovation plus a large 2-story addition on our home four years ago. Mainstream Plumbing handled all the work required for such a big job. From raw plumbing to replacing existing fixtures to installing a new kitchen and master bath, Steve did it all. We were very pleased with his work and continue to call him for all our plumbing needs. He is very knowledgeable and service oriented.

Steven at Mainstream Plumbing is truly a Craftsman in his trade, he helped me renovate my 1930's Tudor to original splendor, he did this using today's more efficient technology. Now my utility bill is half what it used to be. Great work at a fair price. Thanks Steve

Mainstream Plumbing is one of the most professional and reliable plumbing companies I have had the pleasure of dealing with. Steven Silvestri is professional, knowledgeable, and honest.

We have been using Mainstream Plumbing and Heating since 2002. He has completed a variety of services for us. He has supplied and installed a steam boiler, hot water heater and water softener system in our home. He has completed the small repairs and installations as well. Leaky faucet, new hose bibs and washing machine hookup. Recently he replaced our sewer line from our home to the street. Steve is punctual, and honest. His installations are clean and neat. We continue to refer Mainstream to friend and neighbors.

Steven did the plumbing and heating on the renovation to my home 13 years ago and has performed various services, large and small, since. Steven is extremely knowledgeable in all areas of plumbing and heating and performs all jobs himself, as opposed to the larger firms who may send an experienced plumber or a rookie. He will always advise the solution that is best for you, not necessarily what’s best for the plumber or his pocketbook. Steven is a consummate professional; trustworthy, prompt, courteous, friendly, neat and clean, and most importantly to me, will come in the middle of the night or weekend in case of an emergency. Steven has installed and/or maintained for us; a boiler and heating system, water heater, interior foundation drain, gas piping, faucets, fixtures, a water treatment system, washer/dryer, dishwasher, etc. I’ve referred Steven to my mother, neighbors, and would not hesitate in referring him to anyone. I wish I had a professional go-to guy like Steven in every walk of life!

I am happy to recommend Steven Silvestri from Mainstream Plumbing for all your plumbing needs. These days it is difficult to know who to trust when it comes to home repairs and improvements. I always call Steven for my plumbing issues because he is extremely conscientious about doing a good job. He has always done great quality work for me including switching over my entire heating system from oil to gas.

Steven is very knowledgeable and up to date on all the latest and greatest technology in plumbing & heating. He is very responsive and doesn’t need to be chased down. He will always call back in a timely manner and always stands behind his work.


Six years ago we hired a contractor to remodel our home. We replaced our kitchen and existing bathroom and added a second bathroom. We were introduced to Mainstream Plumbing then and they handled every aspect of the plumbing for our remodel. We were so pleased with the professionalism and quality of work with that job; Mainstream continues to be our plumber. Since that time we have replaced our hot water heater and boiler, Mainstream did all of that work as well. Basically, every pipe in our house has been installed by Steve.

When you own a home, it's extremely important to have a team of reliable, trustworthy and quality driven contractors that you can call on when needed. Without a doubt, however, the most important one needs to be your plumber. We couldn't be any more pleased with Mainstream Plumbing and they will be our plumbing contractor for many years to come.
