Buying a house with a possible wet basement...thoughts?
Good morning all. I am looking to buy my first home that I absolutely love. The only problem is that it might have a wet basement. When I first viewed the house, it was around June of 2009, and it had small puddles near the walls of the basement, only one one side of the basement. The agent said he has never seen any water in the basement before. This was in June of 2009. During this past weekend, as some of you may know, the Northeast was literally pounded with 4-5 inches of rain from Friday afternoon through now(monday morning), where at its worst was Saturday evening.
We checked out that basement again Saturday morning, it had no water. Sunday morning, it had those puddles again. The basement walls are bone dry it seems..the center of the basement is dry. I cant see any water lines on the furnace or the oil heater..so it doesnt seem like there have been inches upon inches of water in the basement ever...but who knows. The house was built in 1965, with no sump pump.
My questions/concerns are this:
1. since there are no signs of water on the walls or windows, It has to be coming up from the floor, correct? Will a sump pump fix this?
2. If the house has had no sump pup for the last 40+ years, and has had some ocassional water issues as described above, what kind of structural damage could I expect with the house? Will the floors on the living levels start to squeek..what could possibly happen?
3. I read mixed reviews on drylok and other sealers on the floors. Thoughts?
4. If I went ahead and bought it, would it be prudent to simply drylok and patch up the joints and where the walls meet the floor...along with installing a sump pump + dehumidifier?
I know that a sump and dehumidifier will help..im just concerned with any damage that could have been caused with this untreated basement...Whats the worst that can happen to the structure?
