"The crew was friendly and extremely neat! They jackhammered my basement to install interior French drains and a sump pump and cleaned up after they were finished. They even wiped the mud off my hose and wiped up the floor. They worked like a well oiled machine and were finished sooner than we expected. Would definitely recommend them!"

Foundation Drain Installation FAQs, answered by experts

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

Costs depend on pump type, labor, and site-specific requirements like excavation or drainage lines.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

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.
