Fellow New England property owners,

I have a property in Dorchester that frequently gets water in the basement when it rains. It's a combination I think of where it sits on the slope of a hill and I also think it's seeping up from the ground. Right now there isn't any sump pump, french drain, or de-humidifier of any kind and it likely needs all three. A de-humidifier alone will not solve the problem, I'm talking puddles down there, not just "dampness."

Does anyone have recommendations for a good contractor who can attack this for me? 

Thanks!
