Will definitely use S.S Piping n Heat for all of my future plumbing and heating needs. Would recommend this company to anyone!"

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"Steven showed up and was able to repair our AC after two years of multiple repair companies that could not help. Everyone else said we had to replace when Steven was able to determine that it just needed a quick repair. He was professional and so pleasant. English is not our first language but he was so patient with us. Highly recommend!"

""Henry responded immediately to my repair request for two tenant apartments. He offered to come out the same day, but when that did not work for the tenants, he arrived early the next morning at a convenient time for everyone. He efficiently repaired the showers and toilets. He also checked a few other areas and gave helpful recommendations for future maintenance. His pricing was very fair. He provided a clear written invoice and even gave a written assessment for potential furnace repairs/replacement. I am very satisfied with his work and highly recommend him.""

"Responded immediately to the side effects of a water break in the house. Immediately restored electrical services to dry areas, came back a few days later to restore more services. Gave detailed proposal before work was initiated, had enough supplies on truck to immediately replace most of affected parts. and advised on purchase of replacement fixtures. The technician was cheerful and understood my goals in restoring service."

"I hired Whalen Plumbing to replace a defunct tanked hot water heater at my recently purchased home with a new high efficiency Navien unit in addition to a few other minor plumbing and gas fitting repairs. Ryan and his crew were excellent in both communication and quality of work. I plan on using them for all future plumbing/hvac projects! Highly recommended."

"I hired them for a plumbing project worth $2,500 (that option wasn’t available in the dropdown list), and the experience was excellent. From the front desk to the plumbers, everyone responded promptly and professionally. I had the chance to interact with several crew members, and each one showed genuine care and a strong commitment to customer service. The plumbing team did a great job—I would highly recommend them."
