We moved into a 1960 split-level house in central New Jersey about a year and a half ago and since then I've noticed we seem to have a high water table. In the sump pit the water level is always about 12" to 18" below the surface of basement floor (always more than half full). We do have some minor moisture issues seeping through the first few inches of the cinder block walls near the floor (French drain around the perimeter of basement but no weep holes).
The houses on our block do sit at a higher elevation than the rest of the surrounding area and all our back yards have a modest slope downward away from the homes. There is a sizeable tributary a few blocks from our house, but given our elevation relative to that and the rest of the neighborhood, I don't see how that could be a factor. Yesterday I talked to my neighbor next door (same style house and age) who said he does not have a high water table and his sump pit is usually empty. The house on the other side is vacant so I can't get info there.
Is this normal? Something to be concerned about? Trying to do my homework now and get an understanding as we'll likely want to properly finish the basement in another 3-4 years.
