I recommend basementwaterproofinginc.com for anyone in upstate NY. They waterproofed with bentonite injection and guarantee the work. They did 2 of my houses, my son, my sister and nephew's house and the walls are dry with no mess.Other waterproofers jackhammer the floors and drain water through the walls! I have been waterproofing basements for 21 yrs averaging 4-5 basements a week.
