"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!"

"Mr. Torres was great with all the work we had done. We went to his office where we picked out the color stones for our brick steps and paver walkways. He was extremely helpful with suggestions and patterns. In the middle of the job I asked for an estimate for the side of our house for a walkway and he was able to do that as well as the initial work. The price was very fair and we were very happy with it, we had another estimate for the work and it was astronomical. I would definitely recommend this company and I will be going back to him for future work."

Foundation Drain Installation questions, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

A range of certified professionals can install French drains, from foundation specialists to plumbers. However, you’ll want to make sure that the professional has a breadth of experience installing the specific type of drain you need in or outside your home. Your contractor should also have experience with sump pumps, waterproofing, and flood-proof landscaping.

A sump pump will drain a flooded basement if it has a horsepower strong enough to remove the water faster than it is entering the room. If you have the wrong type or size of sump pump installed–or if your sump pump has failed–you may need to take additional steps to stop the flow of water or remove it manually.

Installation typically takes 1-2 days, depending on the scope and site preparation.
