I had a shower leak trap drain needed to be fixed and also needed to reset and set the toilet bowl. He was very efficient in calling you back and texting everything. He's a really good guy to have as your plumber. A+++. l will definitely use again if any other plumbing issues arise. Great attention to detail from estimate to job."

"I recently purchased a condo and had the kitchen sink replaced. Louie came and did a great job installing the faucet. Several weeks later I needed the guts of a toilet bowl tank replaced. Louie replaced the parts in no time. I had lived in a house for several years and the plumbing was old. On many occasions I called Louie for issues with the kitchen sink, shower/tub, and toilet bowl problems. Louie is very professional and timely, and he is an honest businessman and a really nice person. He is the ONLY plumber I will EVER use and trust."

"Everything went without a hitch. Lou remodeled my bathroom and it looks amazing. He first came in with his demolition crew who worked quickly, cleaned up, and carted away old materials. The plumber also did a great job and everything went smoothly there. Lou then started renovating the bathroom and was fantastic. He worked very hard and finished the job quickly. I would hire him again in a heartbeat and would highly recommend him."

"I've never had a contractor work so hard and fast. Monday was a complete gut job. Tuesday was electric, plumbing, insulation and needed carpentry. Wednesday was sheetrock plus wallboard in the shower. Thursday was tile in the shower and spackle. Friday was tile floor finish sanding. Saturday was painting. Monday was installing of toilet, vanity, closet and finish trim. Done, beautiful twenty seven gold stars."

"I can't find the words to adequately state just how satisfied we were with this significant job. From start to finish John and his crew, Paul and Mike, were absolutely fantastic. They listened to all our concerns and went above and beyond what was called for. During the installation an exterior water pipe was hit that was unknown to us as well as John. John stopped the installation and fixed the broken pipe that was now leaking in the basement. This clearly was not his fault or his responsibility and I was more than pleased to not have to call a plumber! Obviously damage to landscape with this type of work is to be expected, however when all was complete it was clear that John minimized the upheaval to our yard. I would HIGHLY recommend John to anyone in need of a new cesspool system. My only regret is that John's buisness is limited to cesspools as he is the type of individual and buisnessman I would love to use for all of my home repairs!

Plumbing questions, answered by experts

When hiring a plumbing contractor in Smithtown, prioritize professionals with proven experience handling local soil and water conditions. Ensure they are familiar with Smithtown’s plumbing codes and can provide references from similar projects. Ask for proof of insurance, written estimates, and details on warranties. A trustworthy pro will never ask for full payment upfront and will have a local business presence, giving you confidence in their reliability.

Helpful?

Plumbing projects in Smithtown can impact your home’s electrical, HVAC, or septic systems, especially if you’re adding fixtures or rerouting pipes. For example, installing a new water heater or sump pump may require electrical upgrades, while changes to drainage can affect basement waterproofing. Discuss your project with your plumbing contractor to identify any potential impacts on other systems and ensure your home remains fully functional.

Helpful?

In Smithtown, quality plumbing work is shown by neat, well-supported piping, leak-free joints, and balanced water pressure throughout your home plumbing system. Look for evidence that plumbing inspections were passed, such as inspection tags or certificates. A reputable plumbing contractor should provide clear documentation, including warranties and photos of completed work, ensuring all installations meet local code and are built to handle Smithtown’s unique water conditions.

Helpful?

Before contacting a plumbing contractor in Smithtown, record your home’s age, plumbing material types, and any recurring issues like slow drains or water discoloration. Note if your property uses a septic system or connects to municipal sewer, and gather past plumbing inspection reports. Knowing your main shutoff valve’s location and having recent water pressure readings will help your plumber assess your home plumbing system efficiently.

Helpful?

In Smithtown, homeowners should consider the area’s high water table, which can affect sump pump installations and basement plumbing. Salt air from the nearby Sound may accelerate pipe corrosion, so choosing corrosion-resistant materials is wise. Seasonal ground freezing means pipes must be buried below frost lines. Always factor in Smithtown’s soil type and water quality, as these can impact both plumbing design and long-term maintenance.
