"Every time it would rain the side of my yard would flood and get into my house. A close friend recommended Napolitano Brothers Contracting. Jim, James, and Michael Napolitano were great to work with. They installed a exterior drainage system and also water proofed the side of my house. After, I hired them to do a paver patio and driveway, both of which I constantly get compliments. I am glad to have found them!"

"Mario of Mario’s Faucet and Toilet Repairs in Bayshore NY was courteous and efficient. He cleared the clogged pipe and got the plumbing back in working order. He’s been doing this for 10 years so he’s very experienced. I think the price was very fair for the work done. I would highly recommend him for plumbing and drain issues. Thank you Mario!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

"Our driveway came out beautifully! People are complimenting the job left and right. JG landscaping was wonderful to work with. They were prompt, honest, and explained everything along the way. I would upload pictures but it won’t let me attach to the review. I hired them to do more landscaping and would highly recommend!"

"I recently had a roof repair done, and I couldn?t be happier with the results. The team at dryshield arrived on time, were professional, and explained every step of the process in detail. They identified the issue quickly and provided multiple options before deciding on the best fix for my situation. The work was completed efficiently without causing any disruption to my daily life. They cleaned up thoroughly after finishing, and the materials used looked high quality. , and I?ve had no leaks or water damage since the repair. What impressed me most was their attention to detail ? They also offered a clear timeline and kept me updated throughout the process. I would highly recommend them to anyone needing roof repair or replacement. I plan to hire them again for future home improvement projects. Rating: ????? Recommendation: 100% ? I?ll definitely use them again"

Foundation Drain Installation FAQs, answered by experts

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

A sump pump is one of the most common ways to get excess moisture out of your home, but it’s not the only way. If your home doesn't have a sump pump, other options to get excess water out of the basement include trash pumps, submersible pumps, service pumps, and hand-crank pumps. However, it’s worth calling a pro in to assess your situation and potentially install a sump pump for you.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.
