Water in basement

Hi, Just looking to have someone come out and check out the basement and foundation again. We've notice a number of nail pops, and drywall cracks appearing as well as the settlement cracks in the basement getting larger.

I have been getting water in my basement for a long time, this year is worse then ever. We'd like to finish the basement and I'm trying to determine if we need a sump pump, curtain drain or both.
Project Location: Wallingford, CT
I have a sump pump in my basement that is working. Prior to last week's storms, I have never seen it running, but now it seems to have a continual feed of water going into it. It does not seem to be slowing down, as every 33-35 minutes, the sump pump runs to drain the water that collects in the basin. My concern is that there is a leak somewhere that may be feeding into it, but I just don't know exactly where that might be from

30-year-old (DIY project) finished basement & laundry. Recent water damage has compromised the flooring and potentially will create a mold issue. I am considering a remodel upgrade of the rooms. I would appreciate an estimate and your design ideas. Thank you, Jim & Maureen Waldron,

One section of basement gets water during heavy rains, Comes up through floor
Project Location: Wallingford, CT
With a small crack or two on one wall that faces a hill, and two "weep" holes in a concrete floor, and the base of a chimney we occasionally get water in the basement through one, both, and rarely all of these avenues. Over the last 4 years of ownership, no more than an inch or two for 800 sq ft of unfinished area. There is a water mitigation system (not sure if french drain or just drain) in the yard to help mitigate the water from the hill, away from the house, but the small flooding persists. looking for waterproofing, sump pump, or possibly both to keep the basement much dryer and flood free.

Our basement gets water during big rain or snow storms. We live in a very wet area. Water comes in through 3/4 spot. It stays around the perimeter of the basement. About 1/2 deep. Half our basement is finished, half unfinished. We are interested in a quote and to fully solve our water issues. Thank you, Emily

Every time it rains there is one spot in the basement that gets water coming in. I've realized this is due to the land/dirt outside being higher than the foundation in one area. Was wondering if you would remedy this issue.
