Who should I call for basement issue?

[Donovan H.]

I have a duplex that had water issues in the basement this past blizzard/melt/rain.

The story goes:

This is a new duplex for us, came pre-rented, and the tenants who have been there for years said that there was only a very minor issue in one corner of the basement that we attributed to bad downspout planning. The duplex is on a hill with a fairly steep grade driveway., but it is in Toledo, OH which is swampland. It's not in a flood zone though.

The bad downspout ended about 4 feet off the ground at the back corner with the driveway and just basically ends, dumping water straight down. That's the corner that has a slow trickle that runs down to the drain in heavy rains.

The house is from 1927. There is what you MIGHT call a sump hole, but may just be a drain. There is another centrally located round hole that must be another drain of some sort.

Well, it flooded. 3-4 inches. Everyone thinks it's from the corner, but we dropped a pump in the square hole to empty the basement ... When we removed it, water started coming up from the hole itself ... Not the corner.

Luckily, all furnaces , water heaters , washers, driers are ok.

Do I call a plumber? Do I call roto-rooter to clear the drains/sump hole? Do I go straight to a basement waterproofer? Who do I call exactly?
