Get matched with top septic system installers and replacers in Harriman, NY

"Our service was excellent. Our technician, Brian, was on-time and thorough in his workmanship. He took the time to give detailed explanations of the potential and actual problems with our central AC unit and was very personable. We thought our system would need to be replaced, and he fixed it by replacing the compressor motor capacitor, saving us much expense."

"They were great to work with. Very knowledgeable of wells and pump systems."

"S&G replaced our septic system, we are so grateful to the owner Mr. Sandigo & team! We are extremely happy for your work! Thanks"

"You made an effort to come a day before scheduled, you had an extra long hose to reach the septic tank, you checked all the toilets, you gave an excellent tip to remove the bad smell caused by a previous backup (spray bleach and green cleaner worked awesomely) and you were in and out in less than an hour! Highly recommend!"

"Very professional and knowledgeable and conscientious about the quality of work. Kept me in the loop on what was being done and my different options throughout the installation. Made me aware of and sought as best as possible to correct potential issues with settings on my boiler. Educated me and offered good advise for future servicing of my boiler. Excellent service."

"Mattia was great! I had him come by next week and install a new sink and cup washer in my kitchen, I would 100% recommend him and will be calling him in the future."

"Professional tree service at a fair price"

"Job was done in a timely manner. System works as it should. Paid a pretty penny but let's hope it doesn't have to be fix again anytime soon."
