"I dealt with John and Dave. They were always very punctual, the proposal was specific it clearly stated what they would be doing, the size of the septic tank, overflow, main line and the cost. It was all done to code. They were polite, responsive and answered all my questions even after the work was completed, I wish I would have realized or been told how extensive the area that was disturbed would be. I would have removed more of the plants."

"This was absolutely my best experience I have ever had with any company I have ever done business with. No need to look any further, this is definitely the company you will want to do your basement waterproofing . The work that is done and the professionalism of every member of this family run business will exceed your highest expectations. I am an avid researcher when it comes to finding the best company to do a job that I need done. I had an ongoing issue for years with water leaking into my basement. I had 6 top rated waterproofing companies(very well known on long island and beyond) come to my house and present me with why my basement was leaking and how the best way was to fix it. Each company had something different to say and all different ways to fix it. Then came the Napalitano Brothers(Sons James and Mike). These upstanding gentlemen separated themselves from all the other companies I had dealt with. They were polite, sincere, honest, genuine, well mannered, friendly, professional, knowledgeable, and patient. They presented themselves with pride in the work that they would be doing and ensured me that they would be able to provide me with a job that would satisfy me beyond measure. I cannot say enough about James and Mike( they both were hands on in doing the actual work for the entire job) they were true to their word and after meeting the patriarch of the family business, I can see why and where these young men get their loyal, honest and genuine qualities. If every business followed the business model and approach of how the Napalitano Brothers run a company, it would make it easy to pick a company to do a job. Good thing I am steadfast when it comes to doing research on a company and I take my time to choose what company I will let do a job I need done. I could not have made a better choice because there is no better choice out their when it comes to getting your basement waterproofed. Everyone says they are the best, but with the Napalitano Brothers you are actually getting the best. After you check out the other companies, let the Napalitano Brothers be the last one before you make your final decision and I will guarantee, you will do as I did and have them do the job. They will exceed your every expectation and put you at complete ease from start to finish, and even after with their follow up with you once the job is complete. Make the SMART choice which is the absolutely the BEST choice and have the Napalitano Brothers take care of your basement waterproofing. They will be my only choice and recommendation to anyone that I know that will need the services that they provide. Since the completion of the job, back in February 2017, we have had a good amount of rain with a few storms that brought tremendous rainfall and I can say with great happiness and satisfaction that my basement has not leaked even one drop. I am very grateful and thankful for meeting the entire family and workers and for having them do a"

"I actually needed to solve ventilation issues in my basement. I had an EZ Breathe product installed and an old ventilation system removed, added a vent and had a hose run from a dehumidifier to the outside. They did a great job, were responsive, professional, great to deal with and fair priced."

"I was very pleased with Ron. I called him the night before because i was unable to use any water in my house. My pipes were backed up. He promised he would be to my house by 8am the next morning. He showed up early. My family and I were so grateful. He fixed the problem in no time. He was very informative on what the problem was. We have been having problems on and off for awhile and now we cant prevent from having that problem again. He was very reasonably. We were worried it was going to be too much money, but it wasn’t. Very friendly and very happy to finally have a plumber."

"Just had my crawlspace encapsulated. Gabriel, the company’s rep was very knowledgeable and was able to explain what work was needed and the cost thereof. Carlos and his crew were very professional and did a great job. The crew was able to get the job done ahead of schedule. Would recommend this company to neighbors and family."

FAQs for basement drainage channels installation projects in Farmingville, NY

Expect a well-built French drain to last 30 to 40 years. By channeling both surface- and ground-water away from your foundation, the system relieves hydrostatic pressure and helps prevent costly structural damage. Choose a pipe with a quality cloth filter to keep sediment out and extend the drain’s life. A quick annual inspection and routine cleanouts will keep water flowing freely, ensuring the system continues to protect your home for years to come.

Most French drains sit two feet below grade, but depth ultimately depends on the problem you’re solving. For puddling rainwater or snowmelt, a shallow curtain drain at lawn level often does the trick. To handle rising groundwater, pros dig deeper, down to the footing, and run the pipe beneath the basement slab. A drainage contractor will determine the optimal depth for your specific soil conditions and water issues.

A properly installed interior French drain captures water at the slab, channels it to a sump pit, and directs it safely outside, preventing basement floods before they occur. Because the pipe sits just under the floor edge, a plumber can reach it easily for cleaning or repairs. Pairing the drain with a reliable sump pump gives you the best long-term protection.

Hire a contractor who installs drainage systems every day—typically a foundation specialist, drainage contractor, experienced landscaper, or plumber with waterproofing experience. These pros understand slope, soil, and local codes, and they have the equipment to trench safely around utilities. Ask for references and photos of recent jobs to be sure they can design a system that keeps water off your foundation for decades.

Once the drain is in, patch the yard by reseeding bare spots or replacing plants the crew removed. Inside, look for ways to add value—finishing the basement or upgrading interior waterproofing while the space is open often costs less now than later. Schedule a quick annual checkup to flush sediment and confirm the pipe and sump pump are clear. Consistent maintenance ensures the drain functions properly and protects your investment.

Most policies don’t cover the cost of repairing a French drain itself, but they may provide coverage for water damage if the system fails. Coverage varies by insurer, so be sure to read the fine print or contact your agent before any issues arise. If you live in a high-risk flood zone, consider a separate flood policy to close the gap. Knowing your coverage in advance helps you budget for repairs and avoid unexpected costs.
